Well I have avast Professional and lately it has found several components of win xp and internet explorer, DOS, windows media player and others like virus, and TBM as installer detects some virus, orbit, winamp, bittorrent and many others.
i've formatted my pc several times, and installed windows on the hd without having any program already downloaded avast again and continues as detecting virus.
Anyone have any solution to sort out this problem, my avast is already updated.
Thanks
