Thanks much for your reply - and I am not sure if the problem is fixed
or not - I am very hesitant to re-boot my machine.

I went the links you provided, and did a bunch of reading - the file
in question was in the "good" place rather than the "bad" or dangerous
place. The trojan file seems to have something to do with passwords, and
the error I got said nothing about that.

If it is a trojan, how did it get past my Kaspersky anti-virus? This program
has stopped a few others that tried to get into my system, so why would
it fail now? I also have XP with service pack 2 (not 1, which the places I
followed links to indicated that would be a possible cause) - ditto not having
a firewall - which I do.

I am going to have to set it to do a check disc and bite the bullet and see if that cures it, or I come up with the same problem.

At any rate - I thank you all for the links and suggestions - hopefully I will be back soon with a good report. Sure am getting tired of these weekly massive errors.

Thanks again!
Trish
