If you can manage to snag some Anti Virus goodies may I recommend Malwarebytes. I am sure a lot of others will vouch for the awesomeness that program is. Also a good free Virus scanner is AVG all free scanners have their high points and low points or just invest in a free 30 day trial and run it in safe mode then run it out of safe mode. Do that for the Malwarebytes as well; run it in safe mode then run it normally.
I love finding virii on peoples computers and fixing them. My friends build them I just trouble shoot virus problems and software stuff because I am too scared to build a pc. Snapping in the memory always makes me think I am going to break the motherboard or the memory stick lol.
I built this computer. Building computers is easy. When you build it yourself you can avoid all the pre-loaded and trial crap that comes on pre-built computers. You also can get the best of everything...back 5 years ago it was pretty much top of the line, now it is obsolete (almost).
I use AVG free. AVG is AWESOME. It warned me of the attack, but stupidly I allowed it instead of Quarantining it... it was all my fault...FYI I did use malwarebytes, but it had to be run in safe mode.
I think the computer is all back to normal, but I have a lot of catching up to do.
