Malwarebytes Premium | PCMag.com. Every computer I own or install has Malwarebytes on it. It is the first program I install, and it runs in the background all the time. It is fast, small, and competent. It covers the waterfront of computer security; including antivirus, anti malware, anti exploit, and anti ransomware. While you are browsing, it blocks websites that contain malware and adware. Premium costs $39.95 a year; but, you can protect five computers for $79.95. Small price to pay for peace of mind.
