If you're already infected with malware, Malwarebytes Anti-Malware should be your first choice.
The most surprising part of this tool is that it updates daily, so you can trust it to immediately identify and eliminate new threats as they emerge.
Upon your first installation of Malwarebytes Anti-Malware, you'll receive a 14-day trial of the premium version, which includes preventative tools such as real-time scanning and special protection against ransomware.
After 14 days, it will revert to the original free version. Manual scanning is still required, but it remains a top-notch security tool.
Therefore, we recommend running the software to scan your system at least once a week. If you suspect a virus intrusion, use the tool to scan immediately, such as if your web browser suddenly starts abnormally.
Recently, Malwarebytes acquired Adwcleaner, which can target and eliminate programs that capture your browser by opening your homepage, resetting your default search engine, or adding unwanted toolbars.
This software is free and, in addition to anti-malware, it's an excellent addition to any protection toolkit.
