Avast home edition will not scan arches, like winzip or rar, does anyone else have this problem?
if so please let me know thanks at the following
Scannin archives is most useless function. At least for Standard Shield.
For others its not and those are also covered by Home Edition (Instant Messaging and Mail Monitor for example). Don’t worry about this 
Free or Paid for, to me…all the people who write viruses to harm people or cause havit should be lined up and shot.
If you could sit down a write a virus you have to much time on your hands.
The shooting comment is just a figure of speech, but all the virus writers should be tracked down and dealt with.
way back before the net I ran a bbs and had a user try to break into my system and delete my HD and all my users wanted to beat the living crap out of this person. and that was a long time ago.
I guess Rajzor wanted to say that for an virus to activate on your computer, it has to be started. It cannot be started from an archive - it has to be unpacked first. So, if you have the antivirus resident protection running, it will detect the virus and prevent its execution at the moment you try to execute it (after it’s unpacked) - even if the detection inside the original archive fails.
The scanning of archives is just another layer of security.
You can set this security level putting the sensitivity at ‘High’ or using the Customize level and add the archive files extensions to be scanned.
In your download manager, if you use any, you can use C:.…\Avast4\ashQuick.exe (without any other parameter) to scan the downloaded files
