I tryed to install Avast in a “blank” XP system (just XP Pro installed and nothing more). The Avast blocked my DOS programs…). Other Antivirus (in a empty system) didn´t. I tried all the resident scanner options, bypassing 16-Bits and 32-Bits option, I tried not heuristic - because some files zipped from DOS versions of pkzip and pkunzip are .doc -, I tried to disable resident scanning…
All that I get is a blank line of the cursor: C:> :‘( :’( :cry:
