You often have to take a multi-pronged approach to eradicate all the malware. Onw product usually doesn’t do it alone.

First download the following (if the virus is blocking your internet, you may have to download these on another machine and burn to CD or copy to a USB memory stick)

Malwarebytes: http://www.malwarebytes.org/mbam.php

Superantispyware: http://www.superantispyware.com/superantispywarefreevspro.html

CCleaner (cleans out caches) http://www.ccleaner.com

Avast! 4 Home: http://www.avast.com/eng/download-avast-home.html

Now, start the machine in Safe Mode (hit the F8 function key as the machine boots up, and choose Safe mode)

Turn off System Restore on your machine, but only until you get this fixed – many of these trojans get copied into the System Restore files, which anti-virus programs aren’t allowed to touch and the viruses could reinstall themselves from there. My Computer > Properties > System Restore.

Then run Malwarebytes, and clean everything it says

Then run Superantispyware

Then run Avast – If a virus infection is persistent, use Avast to do a boot-scan – click on “schedule boot-scan” and restart the computer

Then run CCleaner

Then turn System Restore back on.

Now install the antivirus program and antispyware program of your choice to do continuous scanning, and make sure you keep it up to date.

Always keep your Windows, web browser and Java software up to date – frequent patches are released to plug security holes.
