Emsisoft Anti-Malware is a full featured Anti-virus / Anti-malware program, with methods to prevent to malware damage with it's Behaviour Blocker (Mamutu). They also offer an Internet Security suite with the addition Firewall, for complete protection.
Malwarebytes Anti-malware is not an Antivirus, therefore cannot replace standard AV software. It's great for on-demand scanning on infected computers. However, some users may use MBAM (Premium) alongside their current Antivirus, but this is something I do not recommend for a few reasons.
If you're looking for an Antivirus, go for Emsisoft Anti-Malware, or for complete protection Emsisoft Internet Security. For on-demand use, the free version of Malwarebytes would be sufficient for weekly/monthly system checks.
