well, I know to give as much information as possible. I've had this problem before and I've just finished looking around and I'm guessing its malware, spyware.
I'm almost for certain this is attached to my Limewire sessions, because this problem didn't start until I installed Limewire. I guess I'm a little lucky the virus or spyware is located on my external hard drive. That has to be because I've put my 'downloaded files' folder on my ext. hard drive, not on my internal which would be default.
So formally, I'll run through the factors. Whenever I enter my external hard drive, explorer.exe jumps up to 100% cpu usage. This has only started after I've installed and used Limewire, which is set to download files onto my external hard drive.
This is where my knowledge stops. I've read around and I'm guessing I should post a log of hijackthis on here. I guess thats the most effective way of doing things? I don't know whether I should run hijackthis before the cpu jumps up to 100% or whether you'll see better whats going wrong if I run hijackthis while its up on 100%. I could do both, but for now this is before.

This sounds like an infection to me. And just because you were downloading to your external hard drive doesn't mean something nasty didn't get on your main hard drive.

Check out this link for some suggestions.
The power of accurate observation is commonly called cynicism by those who haven't got it.

Does this issue stop when Limewire is not running. It could just be a bottleneck due to connecting to a slower Hard device. This can slow a instance of explorer.exe

Try accessing the drive when nothing is writing to the drive. And see if the issue is still there.

It really makes no differance if the drive is external or not it will still spread a virus to all attached drives. If you are using Limewire or P2P programs then make sure you scan the files before you run them and make sure it is a good AV program. Files on P2P are mainly viruses. Watchout for any files that say crack or keygen as these are normally containing viruses and also small files like 128kb or 196kb these are going to be viruses.
I have had to recover many machines from P2P caused infections. USe with caution.

Hi hicabob,

I don't see any malware in your log. I agree with projectfocus that this is some problem with Limewire and your external drive setup. However, we can do another check to make sure it isn't malware, since HijackThis doesn't always see everything.

Please do the following:

1. Please go to the following page and do the initial cleanup steps: Preparation Guide For Use Before Posting A Hijackthis Log

2. Scan again with HijackThis while experiencing the high CPU usage and post the log here as a reply to this topic. Let me know of anything else you have done to fix the problem and any info about changed circumstances.

My apologies for any confusion. HJT logs should not be posted outside of the HJT forum for your own protection. Altho HijackThis can be used for some general troubleshooting, the main focus is malware removal.

I'll explain a bit more via PM.

The thing about people

is they change

when they walk away.--Mipso
