Confuse? I have already confirmed my problem, which is only one problem by means of simple logic. Avast 4.8, when running a full thorough scan from the Simple User Interface will not scan "System Volume Information." I did not mention any other issues. All machines that I have done this show the exact same results. You people keep assuming that it is my setup, and it is not. My ThinkPad X31 works flawlessly. You didn't run the procedure I did either, that doesn't help. If you hadn't noticed in 4.8, Avast! scans the main Windows folders for what seems to be a spyware/startup/memory check before it even touches the first file in alphabetical sequence for a scan. Now granted it probably scans for spyware and viruses simultaneously, but then it doesn't make sense on the first folders it scans. It doesn't do that on the boot time scan at all.
Here are the results of three scans I did recently:
Avast! Thorough scan using the SUI.
65115/1615 (Roughly 14200 files are done in the preliminary check and are scanned twice).
24:25
0 infected files
7.2GB of data.
Avast! Quick Scan on drive C: using right click and pressing "Scan C:\" from My Computer. It does scan "System Volume Information."
~59000 files
Avast! Boot time scan on drive C: by scheduling it from the SUI.
59049 files
1855 folders
So let me add up the numbers. I found that roughly 8000 files were in "System Volume Information." If you take the 65000 I got from the SUI scan, subtract the duplicate files and add in the 8000, I get around 59000 files. Both Quick Scan and boot time scan get me 59000 files.
