Would it take way too much time? Just some thoughts. Unfortunately, a smart virus author could preserve the modification date. So this wouldn't work 100% of the time. The rest of the time it would work, but would be too much work, I think (some programs, like WriteNow for instance, mark files as modified even if they've only been opened). Nice try though. +----------------------------------+------------------------+ | Anton Rang (grad student) | "VMS forever!" | | Michigan State University | rang@cpswh.cps.msu.edu | +----------------------------------+------------------------+

I mentioned doing a checksum and a mod date check. However, the time and trouble problem still holds. +=======================================================================+ |Scott Hinckley - OCS User Assistant AKA - Galaxy's End | |Georgia Insitute of Technology, Atlanta Georgia, 30332 | |uucp: ...!gatech!pyr!ccasths USnail: 345 Peachtree Pl NW | |ARPA: ccasths@pyr.gatech.edu Atlanta, Ga. 30318 | | I reply to ALL E-Mail | +=======================================================================+

I'm writing an article on the various viruses going around. Seeing as I've guinea-pigged my hard disk enough times already and have spent hours finding that this-and-that does or doesn't work, I'd like to hear from anyone who has voluntarily or involuntarily had experience with viruses. Also, I'd like to know which vaccines, prevention tools, or remedy programs you use, which you've found have worked, or which you've found haven't worked. (Vaccine, NOMAD, nVIR assassin, KillScores, Virus Detective, Virus Rx, Interferon, Virex, etc. i.e., any and ALL). Please MAIL results. Don't post. I'll summarize and post the article when it's done. Thanks in advance -- hope my mailbox gets flooded.
