How to Install and Use Malwarebytes Anti-Malware

Designed to supplement your antivirus software, Malwarebytes Anti-Malware removes spyware, adware, potentially unwanted programs and other malicious and annoying software from a Windows computer.

Available in both a free version that requires manual updates and scans, and a $40/year version that runs automatically and includes active antivirus protection, this application is easy to use if you follow a few simple steps.

Note: Malwarebytes no longer lets you download its free version directly. Instead, you must download and install a 14-day trial of the paid version. Just ignore the suggestions to upgrade to the paid version, and the software will revert to the free version after two weeks. (You'll have to endure a period of slow performance while the trial version competes with your regular antivirus software.)
