@maanastr I didn't realise you considered 360 Total Security an on-demand scanner, "Which on-demand scanner is more effective against malware?" So, if you were using Windows 8.1 with Windows Defender, which would you use MBAM or HMP?
Brother I am not considering 360 as on-demand scanner. As per my personal opinion, I dont need these two on demand scanners, If I am having 360TS. Because I compared 360TS with MBAM and Hitmanpro on one my friend's infected system. These two found only 15 and 20 infection each whereas 360TS find more than 100 infection excluding FP. Also see various trojan,malware test results in Malware Hub forum. MABAM and Hitman, showing below average score everytime .....
So,If I were using Windows defender,I would definitely prefer 360Ts over WD,by excluding these two.
( This is my personal opinion based on my experiences )
Yes, but there's a feature called Early Warning Score where can scan in offline mode but uses aggressive heuristic detection and behavior for a files to be detected therefore for advance/experience users only.
