Installing and Using Malwarebytes on Windows
A popular application to remove malware from a Windows computer is called "Anti-Malware," which is produced by a company called Malwarebytes. Anti-Malware will search for, and remove, much of the malware hidden on your computer. Use the steps below to install and use Malwarebytes.
These instructions are for the freeware version of Malwarebytes' Anti-Malware installed on a Windows 10, 8, or 7 computer.
If you know or suspect your computer is already infected with malware, you must restart your computer in Safe Mode before installing Malwarebytes or running a manual scan.
Malwarebytes' Anti-Malware is available in two versions: The "free" version that does not require a fee (i.e., freeware) and the "full" version that requires a fee.
The full version of Anti-Malware provides a realtime protection module. You will not need this version because UD McAfee provides a similar module, and if you install the full version of Anti-Malware as well as UD McAfee, the applications can conflict and cause problems on your computer.
