We sold a 10 user license of version 7.7 to one of our customers. A big customer. Now they have a lot of Word Macro Viri. You can save the infected files, move them, mail them, open, save and close them and there isn't a single warning. Nothing, although all automatic detection features a enabled. If you scan those files manually the viri are removed.

Now their support tells me that we should have noticed that their product does not work in the first year after buying it and that they will have to buy a new support contract to get it working.

So now they have an very unhappy customer and a reseller that sold a them product that is simply not working and of course will never sell it again.
