Posting here on advice from ThunderZ to rule out infections and confirm/deny overheating. Please help. Thx!

machine: Dell Latitude D610 laptop
OS: Windows XP professional

Summary of thread:
Computer has been freezing up about every 10 minutes after start up. I keep hitting the "kill switch" and restarting.
Sometimes on restart the Caps Lock light (A) flashes and then the computer shuts down before ever really starting up.
Sometimes the computer restarts -- only to freeze again in 10 mins.
Tried running Kaspersky and Malwarebytes complete scans, but computer freezes before finishing -- after about 1-5% or 10 minutes.

I think you guys are right about the heat problem. When I put the laptop right next to my air conditioner, it doesn't freeze up.
Now, I have had this laptop for 4 years and never a problem like this. The only thing that may have been a factor recently was I spent a week on a boat where it was salty air and humid. Otherwise, any ideas about a cause and solution?

I haven't added any new programs recently. Not 100% sure I am malware free. I have Kaspersky protection running all the time. Ran Malwarebytes' antimalware scan yesterday -- it found 2 Koobface things and I quarantined and removed.

Attaching screenshot of my current processes running.

At this point I would suggest you post READ and HERE so we can totally rule out any further or other infection(s).

Please download Malwarebytes Anti-Malware and save it to your desktop.

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.
The power of accurate observation is commonly called cynicism by those who haven't got it.
