"A life safer!"
Easy to use and usually quick
Seems to have the best detection rate (or at least one of the best)
To get full protection - as in for it to block spyware and to schedule scans, you need to pay.
My family PC which I don't use has often had infections usually from my brother or dad, to which I've been called many times to fix. I've tried every Antivirus I could get hold of, every spyware program and when none where finding anything, Malwarebytes always saved the day.
It seems to be able to find just about anything. Don't think I've never had an infection issue that this baby hasn't sorted. The only downside as mentioned in the Cons is that the free version doesn't have actual protection and scheduling, simply the free version only finds the stuff on your computer already, not blocking any new ones.
I usually use it as an extra, if an antivirus program I'm using fails to detect something.
