Try a scan in normal mode.
You may want to add some RAM.
I'd go with at least 4GB RAM.  :)

RAM could be part of the problem.
How much CPU are you using during a scan?  ???

2GB of RAM on XP is plenty, that is all I have on mine.

Personally I think a Quick scan would be better suited to your needs.
- With a resident on-access antivirus like avast, the need for frequent on-demand scans is much depreciated. For the most part the on-demand scan is going to be scanning files that would be otherwise be dormant or inert. If they were active files then the on-access file system shield would be scanning them before being created, modified, opened or executed.

I have avast set to do a scheduled weekly Quick scan, set at a time and day that I know the computer will be on. If for some reason my system wasn't on, no big deal I will catch up on the next scheduled scan.

That said it doesn't hurt to do a Full scan when you first install avast, but don't change any settings like scanning archives or scanning all files or it will take a very long time.

WinXP SP3 is 32 bit.  Unless I'm reading it wrong, it has a 3 GB limit. 4 GB can be installed but not fully used.

I also have 2 GB in my XP machine, and haven't noticed any performance problem when scanning.

I did have 3 GB on my Win7 but when I increased it to 6 GB the overall performance including scanning became better.  :)

Well, as the signatures shows I've been running Avast on my Dell Inspiron XP with only 1GB of Ram since 2002 with no issues and other Security software as well. At times I would have preferred 2 GB but have gotten by very nicely with just the 1GB. :)

On a WinXP 32bit machine? ???

Well, after right at 48 hours, the "normal" full system scan completed.  It found 4 files (it found these files in the very beginning of the scan) that it classified as a threat and suggested moving them to "The Chest" - which I did.  It then suggested that I do a bootscan upon reboot and I hit "Okay".  The computer rebooted but it did not kick off the bootscan - I assume because I did the full scan in SAFE mode.  So I waited until windows finished loading, launched avast, scheduled a bootscan and rebooted.  That was at about 7:30pm last night.  It was at 46% at 5am this morning.  It has found quite a few (I won't know how many until it is done & I can review the log) more files that it has classified as threats that I have moved to "The Chest"...

I guess my question at this point is why weren't these files found during the 48 hour "normal" full system scan ???
