How to remove a virus from your computer
Steps to remove tough viruses:
I recommend booting into safemode. As soon as you turn your computer on, begin pressing F8 once every second and then choose SAFEMODE WITH NETWORKING.
1. Download Rogue Killer and do a SCAN and then DELETE what it finds:

2. Download Avira Free and then run a full scan:

If your files are hidden you will need The Unhider:

If you can't run the above programs you may need the Exe Fix:
If you have Windows 7*
https://sites.google.com/site/jeremyscholz/virusremoval/Win7_EXE_fix.reg?attredirects=0&d=1
If for some reason you cannot download these files, go to another computer and download them to a flash drive first, then insert it into the infected computer.
*If you have Vista or Windows XP, download the appropriate EXE fix at the bottom of the page instead of the Win7Exe Fix.
Alternatively:
If you are still able to view this website on your infected computer you should run Combofix.

and if that doesn't work, try Norton Power Eraser:

and TDSSKiller:

or

If your computer is still infected, call helpdesk or use your system restore disks to restore to factory settings.
NOTE: If you restore your system, you may lose all information on your computer that you have saved. Backup your system before restoring.
