Microsoft Defender has improved considerably, but it’s still not as powerful as commercial antivirus software. If a person is using a paid Symantec, BitDefender, Kaspersky security product, he doesn’t have to worry about online or offline security threats.

The paid antivirus programs monitor the computer continuously. If they find suspicious files, the programs will quarantine or fix it. Paid security software are capable of detecting all types of threats. If a person uses a free security software, there’s a big reason to worry. Free antivirus software doesn’t provide protection against ransomware.

Users can improve the security of their PC by installing web-browser extensions. The extensions will block the download of malicious files. They’ll also prevent users from opening harmful URLs.

Firefox and Chrome provide tons of free security extensions. The latest extension to make it to the list of security extensions is Malwarebytes.

What does the free MB extension do?

Malwarebytes extension will prevent users from downloading files infected by malware. Apart from malware, the MB Firefox extension can identify and block websites designed for the purpose of scamming people. It can also block tricky advertisements and scripts that track your online activities.

MB lets users exclude websites from being scanned. To add websites to the ignore list, click on the “Exclusions” Tab.

By default, MB sends some data to MalwareBytes servers. The extension provides an option to disable this feature. Although the extension is experimental, it does a good job of identifying malicious URLs.
