Avast IS gave you a sad face, Emsisoft IS will give you a BSOD (blue screen) unless Emsisoft released a fix for that.
According protection:
Both programs will serve you very well but let's focus on some details:
- Detection-
Emsisoft has better signatures but not far from avast
-Behavior Blocker-
Emsisoft has one of the best behavior blocker but avast has ''evogen'' ''filerep'' and IF you enabled it.....''hardened mode''
-Cleaning Capabilities-
I think Emsisoft is better, however avast has ''boot time scan''.
-Support-
Emsisoft by far.....
- System start up & performance-
Avast
- Memory Usage-
Avast
My personal opinion:
Try Avast free and modify the settings and if you are not satisfied then go and buy Emsisoft ANTIMALWARE.
Emsisoft antimalware is more stable than Emsisoft Internet Security with no any problems.
Overall:
Your system is something that you know better than anybody here. Your internet habits too. Try them and decide with which product you feel more secure.
