I just got a machine from a friend of a friend to fix as he is having some issues with it. well I get it, takes 5min's to boot, every 5 second it flashes up "spyware etc. detected Spybot search and destroy reports >500infections + 20 high security threats. this machine has every form of virus, trogans, adware, sypware, worms, dialers, key recorders everything. every scan shows more and more infections. I tried to install 3 diffrent virus scans(avira, avg, win defender) but none of them work/they all return 0 results(avira allways has 1 or 2). any Ideas? I'm not sure how to fix this, with out putting Ubuntu on it of course. anyone know of good free anti spyware software? or have any ideas what to do with this thing?
