XP Defender has corrupted computer. HELP!

I need to have my son-in-law turn off the router and re-set it. He's been out of town but is back. They have a wireless house alarm system that is run by the computer and I don't want to trip the alarm. As soon as I get him to follow your instructions (this evening) I will complete the steps and re-post.

Thanks in advance!

O.K. I followed all instructions. Reset the router, etc., but still cannot access the internet. I tried several times and kept getting a message saying it was connecting, then another message would flash at the bottom quickly that said something about an "I.E. frame error". There was more to the message but it disappeared from the task bar too quickly to copy. So I re-set the default settings for internet (tools, internet, advanced, security, etc.) but it didn't help. I checked the WAN network and LAN network and nothing showed up as a problem. Next I tried to run ComboFix. The machine doesn't have the recovery console so I couldn't install it but the program said it would run anyway and might take twice as long as the normal 10 minutes if it was heavily infected. About 3-4 minutes into the program the computer rebooted itself and re-started McAfee. I tried ComboFix a second time and it did the same thing. The computer also seems to hang on almost all programs. When trying to access the internet it will show the page that says the connection could not be completed but when I try to close the window the machine just sits there. Same thing with most other programs. By the time I click on task manager and the screen comes up the machine seems to clear itself.

Did Combofix produce any logs? If so please post them on your next reply along with a new HJT log.

You can find the logs under c:/ Combofix

Do you have the disks for this machine?

There were no logs as ComboFix didn't complete the cycle. I tried twice.

It is a Dell machine, about 5 years old, so I'm not sure about the disks. I will ask my daughter. As a last resort there is an IT department where I work and they've offered to wipe it clean and reload Windows and the other software if necessary.

If it is 5 years old and never had a fresh install, well let’s just say that is not such a bad idea. It is amazing how much junk accumulates over the years.

In the meantime let’s look at something else.
