This is because rar files are inactive and even if you have viruses inside a rar file it wont harm your syatem in any way. And when you extract the rar file avast filesystem shield will scan it even before opening the file and if it detect danger it will qurentine the virus before it can even run.I had some experience with Avast not detecting infected files compressed in .rar. You'd have to open the archive first and check it there through Tools>Scan for viruses.
Agree with your point but thats the way avast work. And apart from time/resourse lost there are no security risk.It is inconvenient for the user if after a long/large download, say, a .rar/packed file, say, a repacked- WAIK (which is a 1gb file) downloaded from a site other than Microsoft but a site from a notable forum, the user will be surprised/dismayed that what he downloaded is infected. Time/resources was lost.
