Regarding safety matters, Malwarebytes Anti-Malware is the essential companion for your computer. Where a conventional antivirus focuses primarily on the detection of viruses, Malwarebytes Anti-Malware can detect a wide range of malware ( trojans , worms, rootkits, spyware ... ). This is a free app but during installation you can activate the "pro" solution for a 30-day trial. The main advantage of this version is the addition of an active real-time protection to prevent threats automatically. The updates to the database is also done automatically.
With the free version you will have to remember to do these updates and regularly scan your PC manually. It is a bit more restrictive but it is not an impossible task. The interface of Malwarebytes Anti-Malware is very easy to use with 3 scanning options : a quick scan during which the software will search for the presence of malicious programs with known behavior, a full scan to conduct an analysis of all files on your hard drive (also valid for CD / DVD or USB drive), and finally a flash scan to analyze the programs memories and automatically load when Windows starts. In addition, Malwarebytes Anti-Malware load itself in the context menu of Windows Explorer which allows a simple "right click" on your mouse to quickly verify the potential harmfulness of a file that you just downloaded. If a threat is detected, it is automatically in "quarantine" leaving then the possibility to delete the infected file or otherwise restore it in case of error.
Malwarebytes Anti-Malware Free utilizes Malwarebytes powerful technology to detect and remove all traces of malware including worms, trojans, rootkits, rogues, dialers, spyware and more. Malwarebytes Anti-Malware Free sweeps away malware infections but does not include Realtime Proactive Protection.
Think of it like a malware-destroying broom - you can use it to clean your computer, but your computer won't clean itself (just like Mom used to say).
