I have these in the additional extensions, will they be scanned without modifying the deftask.xml?

I'm confused now but I think not:

If on-demand, you just need to turn on archive scanning.
If on-access, avast by default doesn't look for viruses in packed files. However, it can be enabled by the deftasks.xml file in the avast folder - all you need to do to enable scanning of archives on-access is to add the line

<STANDARD--ScanPackers>EXE;ZIP;MIME;RAR;ARJ;TAR;GZ</STANDARD--ScanPackers>

after the line
<STANDARD--InvalidEntry>1</STANDARD--InvalidEntry>

If you're using avast 4 Professional, the same thing can be done in a more convenient way by editing the resident task.
