Have already used earlier Norton products and was actually always satisfied (Norton Internet Security 2011). Unfortunately, this program regularly deletes programs created by me and finished it while running without that I could do something about it (contains 100% no virus or other security risk). (Programs created with: Borland - Delphi). Also, to my regret, it does not seem to be such a thing as a customer (I really wanted to write a complaint mail) and that is at a not quite cheap security solution more than disappointing. Next time I'll prefer the free competitors.
Incidentally, also another file regularly deleted by me (only a self-extracting archive with I created text documents), which I was but God could exclude Thanks from the Auto Scan ...
