About 7 years ago my PC go hijacked. I tried everything to clean it, no luck until I used Malwarebytes which was brand new at the time. It cleaned the PC so I bought it for $25 to get their real time protection. Got 3 copies which I put on my laptop and wife's computer. That was 7 years ago. Never been hacked/hijacked or got a virus or malware since then. It most certainly offers great real time protection from malware when you surf, but what I like about it most is that it doesn't slow down my browsing like most every other program I've used - either at work or trying things at home. My coworker had a habit of getting virus'd and hijacked about every three months... I put MBytes on his laptop and he's been clean ever since then.
Best $25 I ever spent.
