try malwarebytes. it usually picks up on the real nasties others miss. at least for me.
i have a whole gambit i run on my kids machines and never seem to have any issues. found 49,000+ threats on my aunts machine about 2 months ago... installed the gambit for her and made a pdf file of instructions and she hasn't called me since. i'm guessing she's doing much better now. most adults, i try to convert to linux so i can avoid getting calls every day for issues.
Hmm, I should probably do that for myself. Seems how I just realized that I never installed any anti virus on this pc after I went to windows 7 and my firewall is off for a lan party since I am normally the server there. What linux do you use.
Not trying to jack the thread or anything.
I would listen to dun on this. He is usually right and is pretty good with electronic stuff.
