On 20 Mar 2010 I got some type of virius,I think. In the internet explorer bar the address is info-defender.com/purchase?pchwin&r=68.0 The page says purchase Antivirius software. A window pops up stating my computer is infected in files wsauclt.exe and wschftu.exe, and do I want to stop the attack by purchasing the software.
I ran a Avast boot and full scans, nothing was dectected. When I try to go to another URL on the same page, or open another window, I can not. So, on that computer I can’t even download any program to try to get rid of this problem.
I can get to my files through windows explorer. Also a bunch of sheilds keep appearing on my taskbar. I’m using another computer to post this. So, what’s my best couse of action to fix this problem?

[*]double-click on the Custom Scans box and a message box will popup asking if you want to load a custom scan from a file
Select Scan.txt that you downloaded
[*]Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
[*]When the scan completes, it will open a notepad window with the contents of the scan - OTL.txt
[*]You can either press the reboot button and after your computer has restarted you will see the OTL.txt and a further file - Extras.txt on you desktop.
Post the contents of both files back here.
