I have just joined the forum and look forward to interacting with all of you. I am an amateur computer user at best, but enjoy troubleshooting computer problems (sometimes).
I am having a very tricky issue with an old computer running Windows XP Professional sp3. I am seeing multiple symptoms, but I believe they may all have their root cause in one malware problem. Here's what's happening:
1. I continue to see an instance of svchost.exe take over the computer's memory and CPU. I have tried to troubleshoot this via Windows patches, disabling Windows update, etc but nothing consistently works.
2. When I try to use "Windows Update", my browser goes to the windowsupdate.microsoft.com site but the page will not load. I have tried using both Firefox 4 Beta (getting the message - "problem loading page - connection has timed out")and Internet explorer 8 (getting the message "Internet Explorer cannot display the webpage"). I tried a Microsoft Fixit update (50202) to update all of the Windows Update components but it doesn't appear to have worked.
3. When using either IE8 or Firefox, I get random webpages popping up on a new tab.
4. I have Norton 360 v5 installed and it frequently reports that is has block intrusion attempts or other attacks. I have run full systems scans and, while clearing some problems (Trojan.Gen.2, trojan.Pidief, suspicious.AD, Trojan.ADH.2), it has not stopped the above from continuing.
Thanks in advance for any help you might offer!
