Hi. I hope someone can help me. About a week ago, my main business PC and another in my office was hijacked by a slew of viruses and other malware. I uninstalled McAfee, installed Avast and Comodo Firewall in its place.

Avast began giving me Iframe alerts numbering in the thousands with the occasional Win32 or virut alerts. It has messed with all my settings and I finally got it all put back together and was just trying to get the last few items cleared out.

Then I connected my network cable to update all the malware software (malwareBytes, Dr Web, Avast, Comodo, Combofix) and all heck broke loose. Suddenly I was getting all manner of new alerts and files trying to be (and some successfully) loaded into the system.

After a few minutes of this, others around the office started to get their networks hijacked. I disconnected all PC's ran virus scans on the ones (qty 3) that had not been having problems with none found.

What I found intriguing, was that on each of the PC's, the only real symptom was lack of Internet, but my network settings were all showing connectivity. Finally I discovered that somehow the bug on one machine (the main one - the other is already disconnected) had changed my network settings. Now, if I set my IP and DNS address to obtain automatically, when I go to advanced settings, under "IP addresses", it says DHCP enabled which cannot be removed. I am writing to you on a PC close to my router with everything else unplugged and the settings set exactly for my current connection.

Obviously, you want to only work on one PC, and I believe that if I can get the worst one out of the way, I can clean the others of the minor networking issues. My second badly hit PC I'll post separately about if needed.

So, the main PC...It is an HP Pavilion running Windows XP Home (came with the computer) SP2. I was actually in the middle of the upgrade to SP3 (automatic upgrades) when it blew the gasket the first time last Tuesday. You will obviously want logs of some kind...will it be okay for me to carry the logs physically to this PC with a thumb drive? Or will I spread something?

My bad...I just realized that the network
issues were unrelated to the virus problem.
I am on board and ready to solve the problems
on the main PC.
