So AVG found some worms/virus on the computer; I got the warning "E:\System Volume Information\_restore{DFE8908F-340D-4202-A500-7B1DEAEC694C}\RP38\A0014667.exe";"Virus identified Worm/AutoRun.FR";"Moved to Virus Vault"

I am wary about having a virus hanging out in a folder on my machine, can (how) I delete it? Why didn't AVG just delete it?

This infectiom Is in your System Restore Points folder.
Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.

When an anti-virus or security program quarantines a file by renaming and moving it into a virus vault (chest) or a dedicated quarantine folder, that file is essentially disabled and prevented from causing any harm to your system. The quarantined file is safely held there and no longer a threat until you take action to delete it. One reason for doing this is to prevent deletion of a crucial file that may have been flagged as a "false positive" especially if the scanner uses heuristic analysis technology. Heuristics is the ability of a scanning program to detect possible new variants of malware before the vendor can get samples and update the program's definitions for detection. Heuristics uses non-specific detection methods to find new or unknown malware which allows the anti-virus to detect and stop if before doing any harm to your system. The disadvantage to using heuristics is that it is not as reliable as signature-based detection (blacklisting) and can potentially increase the chances that a non-malicious program is flagged as suspicious or infected. If that is the case, then you can restore the file and add it to the exclusion or ignore list. Doing this also allows you to view and investigate the files while keeping them from harming your computer. Quarantine is just an added safety measure. When the quarantined file is known to be malicious, you can delete it at any time usually by launching the program which removed it, going to the Quarantine tab, and choosing the option to delete.

Creating a new Restore Point and purging the old as boopme instructs, would have removed those files if your anti-virus was not able to quarantine them. In any case, doing as he says still should be done as the last step after disinfecting your system so you have a clean working state to return to if needed.
