Thanks again for the prompt reply. Following advice found in other newbie postings, I've downloaded "The Cleaner" as well as windump and its library accomplice. I will be running them. Although I've run worm and trojan cleaners before (and have come up clean) I'll give it another shot.
But I have a strong suspicion that I've been hacked-because I partitioned my computer one night, wiping it clean and didn't reinstall an os before going to work. When I returned home and turned the computer on, it booted to Win98 through a "network" boot via my phone line. I immediately repartitioned it again and loaded WinXP, (with the phone line unplugged) and it worked ok for a short time. However, after I took a mini vacation, the problem returned. I found files in my computer that had been modified during my absence.
I've informed the authorities (local pd, FBI, and FCC) but the first group is computer illiterate, and I haven't suffered enough economic loss for FBI or FCC to care! Therefore, I've been trying to resolve it on my own.
I'm getting ready to change ISP's again (I do this regularly, when the traffic gets heavy) so I'll watch the routes and see what happens.
AntiOnline is a must for people like me.Thanks again.
