Alrighty, so I'm pretty sure I downloaded a virus with some bleepty game, and I ran Ad-Aware and did a scan in HijackThis, and Ad-Aware found some problems and it supposedly got rid of the problem, but it kept finding the same problem for every subsequent scan I did after the first one. I looked through the HijackThis log and didn't see anything too suspicious, but I'm no pro so hopefully someone else would be able to find something... My CPU usage is usually never more than 10-20% and it keeps running now around 55% and sometimes as high as 100%. If someone could help me out with this issue, I would much appreciate it.

Thanks!

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

IMPORTANT! If for some reason GMER refuses to run, try again.
If it still fails, try to UN-check "Devices" in right pane.
If still no joy, try to run it from Safe Mode.

Is it possible to just show you the HijackThis file? I'm not so comfortable with downloading tons of programs onto my computer much anymore.

It's a very outdated program. That's all I can say.
