I've noticed there's a good amount of misinformation on this website. (sitejabber) If you don't know, don't spout out false information, you'll end up confusing people.
Anyways, Malwarebytes is a great bit of spyware, adware, malware, etc removal software. It is not an anti-virus program and does not provide real time protection. You actually run at a higher risk by not having real time protection. And no, it will not compete with other removal software like stated above. You're thinking of anti-virus software. (AVG, Norton, McAfee, Kaspersky, Avast, etc)
Malwarebytes is quick to install and is actually really quick when you perform a quick scan. It does find quite a bit of infections, however it does not fix everything. I've had quite a few cases where Malwarebytes, by itself, could not remove an infection. Though these computers were badly infected and required a multitude of software to clean everything. However, because it is a quick program to run, I usually install and run this program first, in my cleanup process.
This is a must have program for anyone that needs to clean their system, and of course for any computer technician. If anyone has any questions, feel free to comment on this review.
