I've returned from a business trip which took me throughout the country: Hamburg, Koln, Dusseldorf, Frankfurt, Stuttgart, Munich, Ingolstadt and Berlin.
Without exception Symantec anti-virus is THE choice. This is significant because Germany has the highest per capita usage of computers in Europe and their recession is a bit more serious than ours.
What's important to note here is the companies I visited all have strong overseas operations both in the states and elsewhere. Software policies usually being made by the home office, I surmised these satelite offices must also use SYMC. Very encouraging for us!
