Troubleshooting a Slow Computer

Troubleshooting a Slow PC

Slow computers can be the result of issues such as adware or viruses that can attatch themselves to computers when visiting insecure sites, or from opening suspicious emails and such. Adware is software that automatically displays or downloads advertising material (often unwanted) when a user is online. Software that is designed to detect and destroy computer viruses, antivirus software, can help protect computers from these breaches. 

Troubleshooting a Slow Windows

1) Check for any suspicious or unwanted extensions in the user's web browser

     For Chrome:

  • Select the three dots in the top right corner
  • Select More tools
  • Select Extensions then select remove on the unwanted extension 
    • Note: Example suspicious/unwanted extensions- WebBrowser, I-Cinema, SlimPrice, deals                            

    For Firefox:

  • Select the three lines in the top right corner
  • Select Add-ons
  • Select Extensions from the left then select remove on the unwanted extension

2) Install and run AdwCleaner to check for and remove any adware or potentially threatening software

  • Navigate to the AdwCleaner website herehttps://www.malwarebytes.com/adwcleaner/
  • Select Free Download then run the application once it has downloaded
  • Select yes when prompt for this application to make changes to your device
  • Select Scan Now from the Dashboard menu
  • After the scan is complete, AdwCleaner will show a list of the detected threats. Select Clean & Repair then select Restart Now

3) Install and run BleachBit to clean the temporary caches and system files to free up some space

  • With BleachBit now open, start selecting the options from the list on the left side that you want to clear. 
    • Note: When clearing the temporary files in Google Chrome and Firefox, be sure to ask the user if they want their stored passwords to remain for the websites. If they do, make sure the Passwords option is unchecked.
  • Once you have selected the desired locations to clean, Select the clean button at the top then select delete.
  • Restart the computer once the BleachBit finishes cleaning.
