100% cpu usage

Specs: Windows XP Pro SP2, AMD 900MHz, 1GB Ram
Hi everyone.

I'm having a problem I can't seem to figure out. I have WinXP Pro Service Pack 2. I've installed most of the updates from SP3 but didn't want all of them so I made them custom updates.
I can go online and surf all I want but as soon as I log into a secure website such as Yahoo! Mail, or an online bank account, or anywhere that requires a username and password, my cpu spikes up to 100%. I enter my username and password and then it spikes. It will stay there for about 4-5 minutes and then it will settle down and log me into the secure website.
I have downloaded process explorer but I couldn't really figure it out. I'm not sure how to read the threads or know if that is even what I need to look at. I have looked at Sysinternals Process Utilities to see if there was something that could help me but I'm not sure which one would be best if any. What I really need is something that will list each running service, dll, and anything else that can help me find out what is running when I try to log on. I have tried to stop all services that weren't necessary to run windows and internet but still can't find the problem. The problem is in the services. I have uninstalled any virus protection program that I can find on my system, old and new, but still didn't fix the problem.
Any help would be very much appreciated.

You may have a virus or malware on your system do the following and see if this helps.

Download malwarebytes and let it do a full scan, if it finds anything remove them.


If you don't have an anti-virus program or if you ant-virus program has expired and outdated, then remove the old anti-virus program and download AVG 8.


Both of these programs are free.

If it's broke, then blow that sucka up!

Thank you for the information. I downloaded and ran the Malwarebyte program. I didn't have any viruses, thank God! But I did find that I think my computer was trying to run two different networks. I had a router that was faulty and I replaced it and did a complete setup for the network again. Everything seems to work fine now. I hope it stays that way. I will sure let you know if the problem pops back up.
Again, thanks for your help.
