It looks like whatever you had is gone. From your description it seems like it was a possible homepage hijacking. You can guard against this with SAS. Open SAS, click the prefence button, click the Hijack protection tab. Ensure your homepage is in the box and check both boxes.
Check the avast log for the reason why the files can't be scanned. You should be able to see the file name and path along with the reason. Avast can't scan other security program's quaratined files. That message will be "password protected"
Open avast, from the menu, select last scan results.
The same holds true for SAS, though I've never seen anything in the logs. It may appear on the screen during a scan but I've never whatched it scan.
So, if no problems, you can clean up and update.
