I was in the process of posting here [and downloading as per usual] when suddenly every time I tried to go on a website I would get a page telling me that Internet Explorer determined that the page was infected ... which was especially odd since I was on Firefox.
While trying to understand what was happening, I kept getting popups about infections and attacks and running a software to stop the attacks/infections.
I had experience something similar before that my mom's PC contracted, so I restarted, went into safe mode, went back 3 or so system rollbacks on system restore and restarted.
All is fine now, but BOY that was quite scary.
The only thing I think I added was an update to Java. Maybe they are faking those now.
Don't know.
