Immunet Protect is pretty fast and effective antivirus package that I’ve been using for a couple of months now for scanning backup drives. One feature it’s missing is full quarantine purge. Here’s how to do this manually. You can obviously delete (or restore) files from the GUI, but this requires three clicks for each file. If you end up with several hundred infected files this would take ages.
In default install Immunet quarantine is placed under c:\Program Files\Immunet Protect\Quarantine</b>. These files may be just deleted manually, but you also need to delete c:\Program Files\Immunet Protect\history.db to make them disappear from the GUI.
