yep, had that probelm. its a bad virus. it will eat up your memory or RAM until its fixed. AKA everything will run slower. much slower. games particularly affected.
for me it had to get professionally removed. but the money went to a good cause (getting my PC fixed
).
what happened to me was that within about a week my system memory in my system properties went down from 4GB to 2GB.
no idea what got on there but its fixed now after 2 overnight scans and another overnight removalage of whatever it was.
