We understand your concern, but you need to understand that each and every security programs has its own style of picking up the infected files. Moreover, no security (anti-virus) programs are 100% perfect, also everyday there are millions of malware outbreaks happening in the world. So the time to make a decision on a file as infection would definitely vary due their database (or) virus signature files update timings.
Thanks for answer

For me proactive defence is on first place. McAfee has good detection and i proved it in many situations.

If the On-Access settings of an antivirus is configured by default to scan inside archives (zip, rar etc), detection will occur on the files inside the archive.
Else only when the archive contents are extracted to disk will the On-Access scanner attempt to scan the files. From your above experiment, it appears that Kaspersky scans inside of rar archives by default.
Antivirus vendors tend to disable On-Access scanning inside archives for performance reasons without comprising system security as the moment the contents are extracted or executed - they will anyways get scanned. Scanning inside of archives is usually enabled for On-Demand scans.
