on access scanner not working!

The on access scanner is not working any more.

After every update of the database I check the samples I submitted before. Four of them were added with the latest update. These are detected when using the right click “Scan with Comodo” for the entire folder, but when opening the folder nothing happens. When selecting the now detected samples nothing happens. When I actually run the malware nothing happens, apart from the normal D+ warnings.

What’s going on?

Is it enabled?
