Hi everyone, I've heard that it is fine to have an anti-virus and anti-malware application installed on the same computer (such as microsoft security essentials and malware bytes) but not good to have two anti-virus software's installed. Is the reason for this that free anit-malware tools don't run real time protection in the background (as I know free versions are used for scan only) while anti-virus programs do? If that's the case then would upgrading to a paid version of say malwarebytes (with real time protection) interfere with my anti-virus program's real time protection and slow down my computer? What about downloading multiple anti-malware applications? Is there any advantages to having multiple, free version, anti-malware apps? Thanks for any responses.
