Norton File Scan Won't Run
I have Norton Internet Security 2010 installed on my Windows 7 64-bit PC (latest version of NIS 22.214.171.124).
This evening I downloaded a file from the net and went to perform a quick file scan on it (right click and select Norton Internet Security / Scan Now), however, nothing happened, no scan was performed.
I rebooted my PC and tried again, but as before no scan was performed.
I opened up the NIS control panel and selected Run Custom Scan (from the drop down next to Scan Now) and under custom scan selected File Scan) on the selected file but again no scan was performed.
I tried to scan other individual files on my PC and these too failed to perform a scan.
I also noticed that when the file download completed I didn't see the usual NIS Scan message pop up in the bottom right corner of my screen.
I don't tend to download a lot of files so couldn't precisely say when I last recalled seeing this scan work, but it certainly has worked fine (as indeed has File Scan) within the past month.
Please can someone shed any light on why my File Scan (and automatic download scan) have become disabled?
I have checked the settings and I can't see anything has changed and I am the only person who uses this PC and I have not made any setting changes at all.
I also can't perform Run Quick Scan or Run Full System Scan. This is becoming very strange (and more than a little worrying). However, idle scans seem to be taling place okay from what i can see on the logs.
