Avast scanned my computer with a scheduled scan and found several memory processes infected. When I went to apply an action the apply button would not work. I am using Avast 6 version 6.0.11.25 with update version 110602-2 running on windows 7 Home Premium. Here is a screen shot attached for scan result window.
There’s a new update available:110603-0 
Look at his system infections, I doubt it will even update. Avasts service is even showing its infected on the list from what i can read…
Maybe prepare yourself, I would get ahead on the ball and maybe download this program
Download Malware bytes
http://www.techspot.com/downloads/4716-malwarebytes-anti-malware.html
Run a scan and when the items present themselve try removing them with malware bytes, save a log and post it here when completed
After the log completes I highly suggest checking back here, this issue is out of my experience and looks severe, Essexboy has been notified, he’s the malware expert on the site, he will advise you on the steps to take after the malware bytes scan.
It has nothing to do with updates or infections.

- Detections in Memory - My guess is that you are doing a Custom scan in which you have elected to scan Memory and that all these detections are in memory. Since they aren’t physical files they can’t be moved to the chest, deleted, etc. so there is no action that can be taken, hence the Apply button being greyed out.
The detections in memory are frequently other security applications loading unencrypted virus signatures into memory. Having set off a scan of memory by an antivirus application looking for virus signatures, don’t be too surprised if it finds some in memory.
What other security applications do you have installed ?
The image even when expanded is small but it looks like you have AdAware installed ?
If you have personally I think it is a waste of hard disk space as it is no longer in the top flight of anti-spy/malware applications.
