If you want to increase your protection from new viruses, then you can pay to activate the program to enable real-time protection and other features. The real-time protection module will block infections as they are created or run from your computer. The real-time protection module will also block access to known malware distribution sites in order to protect you from web sites that may be trying to redirect you to known malware sites. Last, but not least, the paid version will also allow you to schedule when you want the program to update its definitions. This will enable you to have the latest updates available whenever you scan your computer with program.
Regardless of whether or not you pay to activate Malwarebytes, we suggest that you install this program on your computer and perform a routine scan with it at least once a week. This will assure you that your computer is being secured from some the newest infections out there.
With the latest update, Malwarebytes has combined their Anti-Malware, Anti-Exploit, and Anti-Ransomware all into one package.
