- Could be done by a virus, of course, but it doesn't sound like a virus
- problem to me... Most people seem to think that destruction of
- information is the most indicative symptom of a virus infected. In
- fact, the most important property of the viruses is their ability to
- spread. Only some of them intentionally cause a noticeable corruption
- of data. Remember, the main goal of the virus is to spread. And, if it
- destroys data in a noticeable way, you are likely to notice it and to
- remove it, therefore it will not be able to spread further...

- This is quite indicative. Most viruses are clever enough not to modify
- any file attributes. What you are actually observing should be
- interpreted in the opposite way - not that something is modifying your
- files with archive bit set, but that something is modifying your
- files in a standard way (via the documented MS-DOS functions), which
- sets the archive bit.
-
- My guess is that you don't have a virus. Probably some kind of faulty
- application.
