How do you know they aren’t a virus ?
As some of these files especially the first three have been targets for malware in the past.
You could also check the offending/suspect file at: VirusTotal - Multi engine on-line virus scanner and report the findings here, post the URL in the Address bar of the VT results page. You can’t do this with the file securely in the chest, you need to Open the chest and right click on the file and select ‘Extract’ it to a temporary (not original) location first, see below.
Create a folder called Suspect in the [b]C:[/b] drive. Now exclude that folder in the File System Shield, Expert Settings, Exclusions, Add, type (or copy and paste) C:\Suspect*
That will stop the File System Shield scanning any file you put in that folder.
Which is why I asked about the malware name given by avast (and the other questions) as there is a possibility that you have a file infecter which targets .exe files.
I see you have started another topic about this, which just causes duplication for those trying to help.
I have replied in that topic, http://forum.avast.com/index.php?topic=111964.0, but you should continue in this topic, hopefully one of the moderators can move this topic to the viruses and worms forum where it should be.
This needs further analysis by a malware removal specialist:
Go to this topic http://forum.avast.com/index.php?topic=53253.0 for information on Logs to assist in cleaning malware. Use the information about getting and using the tools and and attach the logs in this topic, not in the LOGS topic.
Once the logs requested are attached as DavidR has asked, then a malware expert can come in and help you. To start this process, run AdwCleaner, Malwarebytes, OTL, and aswMBR. Attach all logs in your next reply.
The following programme may need to be run several times and no guarantee can be given
Download Sality Killer zip to your desktop and extract SalityKiller.exe
Run the utility SalityKiller.exe on the infected computer
A reboot might require after disinfection.
Download the file Sality_RegKeys.zip
unpack the file Sality_RegKeys.zip
run the file Disable_autorun.reg from the archive Sality_RegKeys.zip
Once the scan is over, from the archive Sality_RegKeys.zip run the file of the registry key:
under Windows 2000 run the registry file SafeBootWin200.reg
under Windows XP run the registry file SafeBootWinXP.reg
under Windows 2003 run the registry file SafeBootWinServer2003.reg
under Windows Vista / 2008 run the registry file SafebootVista.reg
under Windows 7 / 2008 R2 run the registry file SafebootWin7.reg

Follow essexboy’s (malware removal specialist) instructions in Reply #8 above, there wasn’t anything about disabling avast in those instructions (that I can see).
[*]Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
[*]When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
[*]Post both logs
