To get rid of the big stupid virus...
go to
http://www.wnygames.com/files/phxfix.exe when the download comes up click Save then Save In : Desktop
After the download finishes, go to your desktop and click on the program called phxfix
A black box should pop up and then disappear
After that
go to
http://www.realphx.com/disclaimer.htm follow the instructions and download the two programs
after those two programs have taken care of the virus
go to Start -> Search -> For Files and Folders
search for randomiser.exe
delete the files that come up in the search
and you should be clean just change your profile and restart your computer
In the future, be careful what you click on...chances are if something just pops up, you probably shouldn't click Yes. ESPECIALLY if you haven't read what you're clicking Yes for.
