i would also uninstall Ad-aware and SpyBot as you dont need these when you have avast and malwarebytes
Fully agree, even more so if you have SB or Ad-aware running in real time.

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 ???

Any comments??

My current question is: Why, immediately after a normal full system scan, would a bootscan of the same files turn up more threats  ???

How Many background processes are running when CONTROL ALT DEL is pressed. Under process tab?

I am running XP SP3 on a vintage IBM Thinkpad only 25 processes running and a full scan takes 25 mins! on avast default settings. Bet you have lots of spyware consuming the computer resorces!!!!!

1. Download Malware bytes free & do full scan and remove what it finds.
2. download adwcleaner and remove all toolbar crap!

Again we don't know the files are or what the threats are.

The boot-time scan is different to the full system scan and these differences that could be the reason.
The boot-time scan, includes archives and it also scans for PUPs = Potentially Unwanted Program/s - See http://searchsecurity.techtarget.com/sDefinition/0,,sid14_gci1066761,00.html. Not included in this definition are tools which can be used for good or evil, some have been legitimately installed for a specifically good purpose, but could have been unknowing installed for a malicious purpose.

Hopefully you can see why we need some information on what was found, file name, location and threat/malware name.

Thanks to all for your consideration.  I will let you know how it goes the next time I do a full scan.

Topics generally remain open (should you need to come back to it) after time they drop to the bottom of the chronological order.
