The only thing a Win 9x/ME enthusiast should ask from avast! regarding v 5, is that ther be an on access and PERHAPS BUT NOT NECESSARILY an on demand scanner -- NOTHING ELSE! NO REALTIME. ETC.
While it is patently clear that DOS, 3.x, 9x/ME are outdated, I CANNOT EVEN INSTALL SPYWARE WRITTEN FOR THESE NEWER, SAFER SYSTEMS! Try it with Win 95 16-Bit and Netscape 0.86.
For the record, the DOS based systems all the way up to 98 SE, are provably subrecusrsive and thus safer by a factor of at least 16; those who say otherwise are provably full of MS!
