A few days ago, my wife running Windows XP on the HP laptop I gave her a few years ago innocently clicked on one of those Facebook links posted on her wall “supposedly” coming from her friend talking about a cool video link. What she didn’t know was that the link she clicked upon inadvertently installed a nasty worm/keylogging software into her computer and sent those links to her friends which we found out later, clicked on the link too! Talk about the dangers of social networking…
What transpired was that on next boot, her machine ran suspiciously slow, then warnings from her antivirus software came popping up, and eventually came about crashing the whole system on the boot after that, only leaving the wallpaper showing on the desktop.
Adding to the difficulty was that it was one of those malware that loads up even in safe mode.
In the past, I would use live cds like PCLinuxOS 9.1, and Knoppix to boot and rescue the machine using F-prot for linux. I didn’t have the time or luxury to download these cds since they were all now sporting over 700Mb in download size, which would certainly take a couple of hours to download.
I found a live cd after some searches through Google, which does exactly that and sports a significantly smaller download size too (about 50Mb). It’s made by a somewhat known antivirus company, named Avira (I’ve installed Avira on my windows machines in the past, but I’ve settled for Avast and AVG, besides, what more could I ask… they’re free for home use).
The Live CD Rescue disk is located at the tools section of the Avira site.
Heres how to use it:
1. Boot up from the live cd:
2. Select the default option, and press enter. You should boot up to a screen as shown below:
3. Default configuration is to report only infected files. We would like to change that to automatic disinfection by clicking on the Configuration button and selecting the option as shown here:
4. If your computer is connected to the internet, it is possible to update your antivirus db files by clicking on update:
5. Go back to the Virus Scanner tab and press “Start Scanning”. The antivirus software should be able to scan all available hard disks for viruses and malware automatically.
