You also will need to select 'Show hidden files, folders, and drives'.
As Don says, you cannot do anything with it via Explorer.
XP only - don't know about Vista -
But if you are comfortable in the Command environment, you can use commands to access and manipulate the files and folders. I recommend against it, however; each Restore Point is spread across multiple objects.
(Experimenting just now in Windows 7, I find that the SVI is protected against this method of access.)
If the 'bad' files are not in the latest Restore then one can use Ccleaner to remove all older Restore Points.
The easiest way to remove ALL Restore Points is to turn off System Restore for the drive(s).
Reboot (optional). Then turn System Restore back on again.
(Windows 7 has a native capability to clear all RPs.)
- I don't know if / what AV conflict may have.
- The (alleged?) password-protection is curious and may indicate some other corruption. (What Adobe products and versions may be involved?)
- It is conceivable that cleverly written malicious software could hide in a RP. I would cautiously suggest that this might have to implicate a root-kit of some kind - but I'm way out of my depth here.
If the files are password protected then Avast program cannot get into them to inspect.
Do check with Avast to see if they have other reports.
Suggestions - possibly overkill
Disconnect from network. AV off. Hibernation off. Uninstall Adobe. System Restore off.
Reboot. Defrag. AV on, and full scan. System Restore on. Hibernation on (if used). Create a Restore Point. Network reconnect.
Operate as long as feasible. When required, re-install Adobes.
IF there is malicious material, it could have infected any USB/thumb drives too.
Be alert for ANY unusual/unexpected presentations or interactions with the system.
