    I noticed that my cpu is at 100%. Now my computer is running very slow and takes forever to load anything. Also, I tried running a virus scan on it and last I checked it was at 19 hours and still not done scanning? What can I do to fix this?o_O

    Stop the scan from continuing, then open TaskManager and see what process(es) are eating your cpu. Explorer.exe by any chance?

    If you want people to help, you should supply a bit more information. Perhaps you could try downloading DrWeb cureit, it is free and generally quite effective at cleaning infections: http://www.freedrweb.com/cureit/
    It could also be a conflict between two applications. Another scanner to run to check for spyware is SuperAntiSpyware: http://www.superantispyware.com/

    Agree with what Osaban said.

    If the above doesn't find any problems, you might have 'legitimate' programs chewing up your CPU. For example, any online games connecting at startup? You have MSN installed and 50 people hitting you with messages when you log on, limewire connecting at startup (can stay connected even when you close the program)?

    Which browser are you using?

    Also, if the above scans are taking too long, try scanning with prevx CSI.
    http://www.prevx.com/freescan.asp

    Should only take a few minutes to scan. Doesn't remove infections (only paid version does), but can tell you if there is say a rootkit, or any other more severe problems.

    Hi rhserika18, download the free or trial version of Anvir Task Manager Free edition:
    http://www.anvir.com/taskmanagerfree

    It will provide an easy to understand listing of files running on your system. It will also try to guess if some apps are a possible risk (and highlight in red). You can also see which app is using most % of CPU.
    To check if that program/process is possibly a virus, just right-click on it and select "check with antiviruses on VirusTotal.com". Anvir will upload the file to VirusTotal.com where it will be checked by 39 antivirus software. If its a virus atleast one of the scanners will catch it.

    The system process is using 100%. I also looked at my system properties under process explorer and under the threads tab usb port system+0x5e96n is using anywhere from 88-99% of the cpu.
