Computer HDD runs constently, CPU fan runs too

[jjohnston]

My wife's Laptop HDD runs constently, like its working overtime on something. and her CPU fan comes on freequently even when its just sitting on the table. I ran a virus scan using Microsoft Security Essentials, Ran spyware scan using ad aware and also spy bot.

She is running windows vista, and we do have a wireless network for internet access.

What could be causing all this processing or activity? How can I bring it back to normal?

Lets get some other scans in and see whats going on.

Please download Malwarebytes' Anti-Malware from here or here and save it to your desktop.

• Double-click mbam-setup.exe and follow the prompts to install the program.
• At the end, be sure a checkmark is placed next to
  • Update Malwarebytes' Anti-Malware
  • and Launch Malwarebytes' Anti-Malware
• then click Finish.
• If an update is found, it will download and install the latest version. Please keep updating until it says you have the latest version.
• Once the program has loaded, select Perform quick scan, then click Scan.
• When the scan is complete, click OK, then Show Results to view the results.
• Be sure that everything is checked, and click Remove Selected.
• A log will be saved automatically which you can access by clicking on the Logs tab within Malwarebytes' Anti-Malware

If for some reason Malwarebytes will not install or run please download and run Rkill.scr, Rkill.exe, or Rkill.com but DO NOT reboot the system and then try installing or running Malwarebytes. If Rkill (which is a black box) appears and then disappears right away or you get a message saying rkill is infected, keep trying to run rkill until it over powers the infection and temporarily kills it. Once a log appears on the screen, you can try running malwarebytes or downloading other programs.



Download the HijackThis installer from here.
Run the installer and choose Install, indicating that you accept the licence agreement. The installer will place a shortcut on your desktop and launch HijackThis.
