10 easy steps to clean your infected computer

Look for issues characteristic of a malware infection:

• Does your web browser freeze or become unresponsive?

• Do you get redirected to web pages other than the ones you are trying to visit?

• Are you bombarded with pop-up messages?

• Does your computer run slower than usual?

• Do you see new icons on your desktop that you don’t recognize?

• Are your fans spinning suspiciously louder or harder than usual?
  
  

Unfortunately, even if you see nothing wrong with your computer, there may be trouble brewing under the surface, sneaking around and screwing with your files undetected. So it’s a safe bet to move on to the next step even if you can’t find a symptom.

Remove CDs and DVDs, and unplug USB drives from your computer. Then shut down. When you restart, press the F8 key repeatedly. This should bring up the Advanced Boot Options menu. Select Safe Mode with Networking and press Enter. Only the bare minimum programs and services are used in this mode. If any malware is programmed to automatically load when Windows starts, entering safe mode may block the attempt.

This includes documents, photos, and videos. Especially cat videos. Do not back up program files, as those are where infections like to hide. You can always download these programs again if files are lost.

If you had no trouble connecting to the Internet before you suspected the infection, you can leave Safe Mode after having backed up your files and return to using your “normal” system. If your Internet was jammed up by a suspected infection, try using a friend’s computer to download your scanner and move it to your machine using a USB drive . Follow set-up instructions and install the program.

You may download an on-demand malware scanner such as Malwarebytes (https://www.malwarebytes.com/mwb-download) to scan your computer.

If you truly believe you are infected, just go directly to the scan. If you do have an infection, your on-demand scanner should let you know that you in danger. A list of scan results tells you what malware was found and removed. Some cybersecurity software also flags potentially unwanted programs (PUPs) and puts them in the corner. If you’d like to keep a program your malware scanner deems is suspect, you can add it to an exclusions list and go about your day.
