Virus Blocker log says file is blocked, but I can still download it

When downloading over the Web, small files are blocked with a block page. Larger files are treated differently: they are fed to the client at a slower rate than they are actually downloaded, so the client does not time out while the download happens.

When NG Firewall has finished scanning the complete file and determined it does not contain a virus, it will "release" the rest of the file immediately. If a virus is detected, however, Virus Blocker will refuse to send the rest of the data. This means for large files the Event Log says the file is "blocked", but checking the file size on the client will show that you do not actually have the complete file.
