Thanks bachoe and everyone!
I am only like 1/4 Computer Saavy!
OK, this is just general advice-- there are several ways to proceed, but one path:
1- download & install AVG, (free) and update it.
2- download & install Ad-Aware SE (free). Update it.
3- reboot in "Safe Mode"-- this is usually done by tapping the F8 key during boot-up. A menu offering several choices will appear, pick "safe mode" and proceed. Be warned, it is very slow to boot like this.
4 - now run Ad-Aware with a "full system scan" and let it clean out the nasties. Follow that with AVG-- you want it to scan everything.
5- reboot normally and run an online internet scan just to be sure-- Trend Micro and Panda are very good. So are bitdefender or RAV.
Be advised of two things-- the above is not gospel- some people swear by Avast and Spybot Search & Destroy... you need one that get viruses, and one for spyware, because they look for different things.
The other thing is some of this new malware regenerates, and is incredibly hard to eradicate. It can be done, but if a few tries with some of the things I and others mentioned don't work, you need to join a forum, learn what format they use, and ask for help.
Good luck- malware propagators should be horsewhipped, in public.
