Kaspersky Internet Security licence renewal instructions

These are the instructions to follow when renewing the licence on Kaspersky Internet Security. I’ll presume that you have a new licence key to hand from a recent version and that the product is the same (eg not Kaspersky Pure etc). If you don’t have a new licence yet, you’ll find them for sale at discounted prices here [Hint: search for ‘kaspersky internet security 3 user’ or however many computers you need to protect]

You can buy the new licence in advance of your current product expiring, but you don’t need to wait until the existing licence has expired to install it any more. Kaspersky now seems to add on the remaining days from your current licence to your new licence, providing the product is the same.

First, open Kaspersky. The quickest way is to double click the icon in your system tray (bottom right of your desktop screen). If you can’t see it there, use the little arrow on the left to expand the icons and find it. It’s a red letter K like this one below:

 

kaspersky-internet-security-1

 

 

Now, look in the bottom right of the Kaspersky window and click on ‘License: xx days remaining’ (where xx is your actual days remaining).

 

kaspersky-internet-security-2

 

 

Now click on the ‘Enter activation code’ button.

 

 

kaspersky-internet-security-3

 

 

Finally, type in your activation code, or copy and paste it if you received it by email. Be careful to get EXACTLY the right code as some letters do look similar! You can copy and paste the whole of the new licence key into the first entry field, it will separate them for you.

 

 

kaspersky-internet-security-4

 

 

Press the ‘Save activation code’ button and you’re done. Give the PC a restart, open Kaspersky again and you should be able to see your licence has the correct amount of days remaining.

I sell full versions in my shop here at discounted prices that are often much cheaper than renewal. Grab the code from those and you won’t need to install anything, just follow the method above.

 


Avgidseh.sys error when starting Windows

avgidsehSince I wrote the original avgidseh.sys fix article, there have been lots of other affected PCs that have passed through our workshop. This is not a rogue update fault now as it was back in late 2010, rather an issue that is, as yet, untrackable to a single problem. AVG are getting the blame for many bad startup errors as the users only see the last driver to load which is often AVGIDSEH.SYS. I have, however, noted that applying an AVG-specific fix works in many cases.

To resolve issues that are AVG related, follow the steps below.

Boot your PC with a boot CD. I recommend UBCD4WIN which is an excellent tool to have in your armoury for PC repair. Download the program and install onto your computer. Build an image from your Windows XP CD (required). If you don’t have a Windows XP disc then you can download the AVG boot disc from here. Please make reference to my original avgidseh.sys fix article for creation and method. Use my updated folder renaming fix listed below in both cases.

What we shall be doing is renaming the AVG folders so they are not loaded on startup. For UBCD4Win, start the computer with the disc inserted and boot from it. This may involve changing the boot order that your PC or laptop uses. Once we have a new ‘environment’ – that is the computer is running from the CD – then we can start a file explorer such as A43, Agent Ransack, Xplorer2 or Free Commander. This will give us access to the files on the hard drive. Folders to rename are as follows:

Windows XP and 2000 (Note: AVG2011 does not run on Windows 2000 so forget a reinstall afterwards!)

  1. C:\Program Files\AVG  –  This is also named C:\Program files(x86)\AVG  when you have a 64bit operating system
  2. C:\Documents and settings\All users\Application data\AVG8
  3. C:\Documents and settings\All users\Application data\AVG9
  4. C:\Documents and settings\All users\Application data\AVG10

Windows Vista, 7, 8 and 10

  1. C:\Program Files\AVG  –  This is also named C:\Program files(x86)\AVG  when you have a 64bit operating system
  2. C:\ProgramData\AVG8
  3. C:\ProgramData\AVG9
  4. C:\ProgramData\AVG10
  5. C:\Users\<user>\AppData\Roaming\AVG8
  6. C:\Users\<user>\AppData\Roaming\AVG9
  7. C:\Users\<user>\AppData\Roaming\AVG10

Example:

rename C:\Program Files\AVG to C:\Program Files\OLDAVG

Once renamed, they will no longer load on startup.

 

Avgidseh.sys is not the only possible cause…

Now I like to run a CHKDSK while still in this ‘running from cd’ environment as it fixes any errors on the hard drive. These are often caused by the PC being shut down while writing to the drive and can also be the main reason the computer failed to start, don’t always blame AVG because the avgidseh.sys driver was the last thing to load! In UBCD4Win we would run Disk Check which does a full scan and repair of the sectors on the hard drive. Just fire it up, tell it your target drive (usually c:) and let it run. Have a cuppa as this takes a while.

The professional method

If you want to do a complete scan and repair of your disk using a professional repair tool that we use in our workshop and lab, you should investigate HDD Regenerator. We have carried out a full review of HDD Regenerator here. It has fixed the majority of the faulty drives we see that cause constant ‘looping’ of the Windows boot procedure and it’s in daily use in our workshop. It’s not too expensive and is a better solution than the free methods we list above for many people as it is much easier to use. It also blows CHKDSK into the weeds for being able to recover data and salvage your hard drive. Where CHKDSK marks the sector as bad, HDDRegenerator actually recovers the data from it and moves it to a new, good sector. As mentioned, this tool isn’t free (it does give you a free trial) but you can buy it once and fix as many drives as you want with it. It also creates a simple to use bootable USB drive or CD/DVD disk for you. Any self-respecting PC geek or computer repair shop shouldn’t be without it in the toolkit.

Check out HDDRegen here

As mentioned in other articles, despite AVG being a capable free antivirus, I heartily recommend the brilliant Kaspersky Pure as a set and forget internet security solution. Here is my method to get the cheapest Kaspersky Pure and be fully protected against viruses and malware.

Finally, let me know by commenting below if this avgidseh.sys fix works for you and please leave any other information you can share with the community.


What is a shebang in Linux?

shebang script explained

Known as a a shebang or a bang line, this is just the characters at the very start of a Linux script. It is simply a hash or number sign followed by an exclamation point character (#!). This is then followed by the full path to the interpreter, for example /bin/bash

Think of it as a necessary code mark that tells the system the absolute path to the Bash interpreter and you’ll not have a problem.

More info on how to use and execute Linux scripts here


Four ways to execute a shell script

shebang script explainedIf you need to execute a shell script and can’t get your head around the conflicting information out there, I’ll try to clear things up. There are quite a few ways to execute a shell script and each has its pros and cons. If you are coming from a Windows environment where the file extension dictates how we handle the file, then try not to think like this. A script can have no extension but still be run. So, let’s take a look at our four ways to execute a shell script.

 

Execute shell script by calling the filename (Method 1)

This method simply changes into the script’s containing directory and calls the script’s file name to execute it.

We can change into the directory first

 

and then call the script thus:

 

Now, my preferred method is to consolidate these 2 lines into 1 , calling it from any directory by simply adding the full path to the file:

 

If you have the shebang at the start of this script, then it will be executed by using the command interpreter that is specified directly after it.

Execute shell script by specifying an interpreter (Method 2)

You can also run a shell script by specifying the interpreter. You do this by adding the preferred interpreter within the command thus:

Execute the script using the bash interpreter

 

Execute the script using the sh interpreter

 

There are usually several interpreters available such as bash, sh,  csh, ksh and more.  Note that if you use a different interpreter in the shebang, this will be overridden by the one you specify.

Execute shell script with . ./ (Method 3)

If you execute the shell script by using . ./ (aka ‘dot space dot slash’), it will not fork a sub shell and you’ll see it executed in the current shell.

 

Why do this? Well it’s normally used after we have changed something in the .bashrc or .bash_profile. Using this method of execution we won’t need to logout and login again.

Execute shell script with source command (Method 4)

source is a bash shell built-in command that executes the contents of the file, which is passed as argument, in the current shell. It has a synonym that you can use which is the dot or period (.)

This can replace the ‘dot space dot slash’ method.

 

A word of warning here though because ./ and source are not quite the same.

./myscript runs myscript as an executable file in a new shell
source myscript reads and executes commands in the current shell environment

To help further, ./myscript is not the same as . myscript, but . myscript is exactly the same as source myscript

 

Do you have a preferred method for executing shell scripts and if so, why? Let me know below.


Cannot find unread emails in Gmail inbox

I have had quite a few customers calling over the years to say that they cannot find unread emails in their Gmail inbox. It’s a common complaint and one which I have found can be quickly cured by doing the following.

Logon to Gmail in your browser (Chrome, Firefox, Internet Explorer, Safari etc).

Go to the search bar at the top of the Google page (the one with the blue and white ‘magnifying glass’ search button that looks like this):

cannot-find-unread-email-inbox-gmail

In that box, type this:

is:unread in:anywhere

Note that there is a space after the word ‘unread’ but not anywhere else. Copy and paste my text above if you aren’t sure.

Now press enter and you should see all of your unread emails! You can click to read individual ones or select them using their check boxes and then do ‘More’, then ‘Mark as read’.

Try some new search terms to get more out of Gmail

If you want to take things further, there are lots of useful search ‘operators’ that you can use within Gmail too. Get used to using these and you’ll open up a whole new level for this great email tool. Here’s a list of the most popular ones:

 

What you can search by Search operator & example
Specify the sender from:

Example: from:amy

Specify a recipient to:

Example: to:david

Lowest prices on Norton Antivirus renewals

cheap norton security discountBeing asked often about where to find the lowest priced Norton Antivirus renewal made me come up with this article. Symantec offer a renewal by credit card that is often too pricey for most people. With Norton Anti-virus being a capable product, it’s a shame to uninstall it so here are a few tips to get a new and fully licensed program at a much reduced price. And there’s nothing illegal about it!

You don’t have to uninstall your current product, simply buy another package (at much less than the price to renew your licence!) from our software shop which will open in a new window for you. When you open it up, use the serial number you find inside. Type this into your existing product and you’ll get another 12 months of updates (or more if you buy a 2 year package).

Remember to match the amount of user licences you have, eg if you have 3 PCs buy a 3-user licence.

Install mod_GeoIP2 on Apache2 in CentOS 7

geoip-centos

If you need to install the excellent mod_geoip2 extension for Apache2 then it can be done fairly painlessly. First off, we need to make sure that we have gcc installed:

 

If you don’t have it then you could ‘yum install gcc’, but I prefer to install all development tools because they include gcc anyway:

 

Install the GeoIP development package

 

Install mod_geoip2 by fetching the latest version with wget. To check the latest version, take a look here first:

https://github.com/maxmind/geoip-api-mod_geoip2/releases

 

I’m installing 1.2.10 here with this, but replace the code in lines 1, 2 and 3 here with their latest version:

 

Now we use the apxs (Apache Extension Tool) to build our extension modules for Apache:

 

If you haven’t got apxs then you’ll need to install httpd-devel.

Be aware that this overwrites httpd so backup your server in case this fails or you get strange results.

 

If this fails with “Error: Nothing to do”, then it’s fairly common. You’ll probably find that /etc/yum.conf is blocking the installation. We can get around this by either editing the configuration file or typing:

 

You should now have mod_geoip2 installed on your server!


Who or what is [email protected]?

 

root notty whm ssh hackedIf you’re looking through WHM’s process manager and you see [email protected] mentioned as one of the processes, don’t be alarmed. It’s perfectly normal and it’s definitely not some hacker called ‘Notty’ who has suddenly got root permissions. Be honest, you’re here because you thought that 😉

You may also have seen sshd: [email protected] in the output of ps aux too.

Why notty?

The term ‘notty’ just represents ‘no tty’ which roughly translates as meaning ‘no terminal’. When you login locally to any Linux machine the terminal will always appear in the process list as ‘tty’. If a connection is made via SFTP or you are copying files with SCP (as I did here on a test server prior to bringing up the screenshot above) then it will show as no tty (notty).

Where does TTY come from?

Many years ago, user terminals that were connected to computers were clunky and noisy Electro-mechanical Teleprinters also known as Teletypewriters. They took the latter phrase and chopped some characters out to get the TTY abbreviation:

TeleTYpewriter = TTY

Since then, TTY has been used as the shortened name for a text-only console. Here’s a teletypewriter in action:

 

 

Now you can’t say that things haven’t progressed!

 

 


Use linux boot disk to repair a Windows NTFS disk fault

Yes, you can use a Linux boot CD to repair a Windows NTFS disk fault. Linux ships with a utility called badblocks. Badblocks is a Linux command in its own right that has several different modes to be able to detect bad sectors on our hard disk. Once found, it saves the references to these bad sectors in a text file so we can tell the operating system to avoid storing data on them.

For the explanation below though, I’ll be using the fsck command. Why’s that? Well fsck is a really powerful command that actually runs those relatively complicated badblocks commands for you, checking or repairing errors in your filesystem and doing all the leg work for you.

Geek fact – fsck stands for “File System Consistency checK” which you can amaze your friends down the pub with. Or not…

Let’s open a terminal window and fire up this bad boy then. You’ll need superuser/root permission to run each of these commands so I’ll add ‘sudo’ into them all. I like to start by running the parted command to list my drives:

This should output the installed drives to the screen so you can note down which one you want to work with.

Now let’s run fsck on the disk. Please note that this can take several hours depending on the speed of your system, the size and speed of your disk. If no filesystems are specified on the command line, and the -A option is not specified, fsck will default to checking filesystems in /etc/fstab serially.

IMPORTANT – We must unmount the disk first or data corruption may happen. To do this, open a terminal window and type:

Replace “sda1” with the disk you need to repair. Now we can run the fsck command safely against the drive:

This fsck command forces automatic bad block checking and it automatically marks all known bad sectors as bad too.

The switch options I often use are:

-m  I use this for safety because if the drive is mounted you won’t be able to scan (and corrupt) it this way.

-c   Displays completion/progress bars

-f   Force a check even if it is clean

-v  Verbose, because I like to see words!

 If you’re booting back into Linux, make sure that smartmontools is installed and enabled:

Enable “SMART” in your BIOS if it isn’t already and run an extended offline test with:

To see a nice overall view of system health, type:

Have a look at the relevant manpages for more info:

 

In my repair shop I only use HDD Regenerator these days.  It’s a bootable software that can fix errors on all types of disk, formatted in all manner of filesystems as used by Linux, Mac, Windows and more. We have this loaded on our drive test rig and repair hard drives daily with it.

If you want to make it easy and have a USB/CD/DVD bootable tool that will work safely on all the drives it comes up against I’d suggest you look at my hdd regenerator review here or buy it direct from their website here

  
 


Cheapest Norton 360 renewal

cheap norton security discountI’m frequently asked by customers how to get the cheapest renewal price on Norton 360.  Symantec’s renewal price is really one of the highest for any Internet Security product.  It is a capable package though and worth keeping on your PC. The best way by far is to purchase a new fully licensed program at a reduced price and install that. Nothing underhand, just a new product at a price much lower than Norton currently quote for renewal.

The beauty of this is that you don’t have to uninstall your current product if it is the same ‘family’ as the one you are installing, simply match the product family. For example, if you have Norton Security, get a Norton Security package with any version number as they all qualify for Norton’s free upgrade to the latest version anyway! If you have the older Norton 360 then get Norton Security and uninstall Norton 360 first.

Do Norton really offer a free upgrade?

Yes, most versions of Norton qualify for a free upgrade to the latest version in that product family. If you download the latest installation program, Norton will auto-detect and remove your older version and then install the newer one too, making it even simpler to install.

Please note

You can change to another security software at this point. From doing lots of virus clean-up work and labs testing, I would recommend uninstalling the Norton product and installing my preferred security suite and consistent labs test winner Kaspersky Total Security. Norton is quite capable but Kaspersky definitely has the edge on speed and low resource usage.

A word of warning. Norton products such as Norton 360, Norton Internet Security and Norton Antivirus are now retired in favour of “Norton Security” and “Norton Security with Backup”. Confused? This article explains more: New Norton product family (opens in a new window).

So to recap, if your Norton 360 has expired, then take a look in my software shop (opens in a new tab) and buy either a Norton or Kaspersky product at prices cheaper than Symantec’s renewal rates. If you want to upgrade to another software product (such as Kaspersky) then simply uninstall the existing Norton software, restart the computer and then install the Kaspersky product.
