Not sure if its a virus - PC running very slow

[karlosio]

Hi, im not sure whats going on with my PC, firefox keeps closing every so often and I also cant display the task manager by pressing the CTRL + ALT + DEL combo. The PC also seems to slow down like the whole of its CPU usuage is being used, but im not even using any CPU heavy applications (just firefox).

Im using Windows XP Pro.

I read your thread on Hijack This and downloaded the app, here is what it produced in the scan.

Any help appreciated, thanks

Howdy karlosio,


No infection showing here. Little of anything else either. No XP patches/upgrades or IE upgrades? Looks to be running some form of server setup as well like that. Surprised there is no infection given that.


Let's do two things at once. As this shows zero attempts of upgrading, we'll need to be sure we can move forward within CTH's minimal rule about not assisting on systems that do not have authorized OS installs. Please visit this site:

You just need to run the "Validation Wizard". Then copy paste in this thread the entire text you receive.



And Go Here and download Silent Runners to your desktop. Run it, and post back here the log it creates. If your AV queries the script, allow it to run. It's not malicious. It will create a file named Startup Programs, and will notify when the scan is complete. Copy the log from the Startup Programs file back here. You can use separate posts here if needed.
