Very fast and lightweight(this is very important for slow computers)
Uses 2 powerful scan engines (Emsisoft's own one + BitDefender antivirus engine) to find most of the different types of malicious software.
Outstanding fast support
Big community of an active users
Can take a time on the first malware scan
This is my preferred antivirus tool because it is incredible fast, lightweight and has double protection by own antivirus engine + perfect antivirus engine from BitDefender. This is really unique combination which leaves no chance to viruses. So far, I didn't see analogs on the market. Previously I used a few antivirus systems at the same machine but now this time is gone - it is enough to use the only Emsisoft and that's it.
