I have been fighting whatever virus/malware/spyware ... that has been on my computer for a couple months now. I run Windows XP Home Edition and whenever I go online, my fan begins to run high. At first I believed that perhaps it needed cleaning, but then I realized that when i opened process explorer, the process: C:/Windows/System32/svchost.exe -k netsvcs was continually eating up more memory and using 95-100 of the CPU. Occasionally it subsides and stops its "resource hoarding" but sometimes it will completely bring my computer to its knees. Also, recently Google searches have been redirected to search sites and pages other than the one I would click on. I have tried looking around on the forums for any kind of indication of what I should do/try but nothing seems to address my specific case.

So I come before the masters and ask for directions to help my computer return to a better, more efficient state. What do you need me to do?

This is actually not too uncommon these days from my experience. Just one thing. Have you tried Malwarebytes Anti-Malware yet? You can download it from www.malwarebytes.org. It is a great little program, and it really knows how to bite malware in the butt. After downloading and installing the program, make sure to leave the following checked: update malwarebytes Anti-Malware and launch malwarebytes Anti-malware. If an update is found, the program will update itself. Run a quick scan an then post back the log so that we can see what is actually going on here. And by the way, what antivirus do you use on a regular basis?

I actually have heard of Malwarebytes and have been using it. I feel that whatever is going on is more sinister because I just did a scan recently and appear to be clean. As far as anti-virus software, I have used a variety and haven't really stuck with anything. What do you suggest for a good anti-virus that is free to use and efficiently uses CPU resources?

What else can I try to catch this problem?

Below is my most recent run of Malwarebytes:

Greetings again... although malwarebytes comes back clean, I ran gmer.exe and got back the following log. What do you make of it?

I find the svchost JMP instructions interesting and wonder if that points to anything suspicious.

Any help will be greatly appreciated :thumbsup:
