I was actually quite pleased with GData of the AntiVirenKit 2005 decided to upgrade to the complete Internet Security 2006. But what was a complete letdown. Installation was simple and straightforward. After the default restart the computer once went nothing more. After an hour at least configuration functioned again some programs ... well ... until you restart the computer. Each Restarting the computer put out misteriöser, some settings. My emails on T-Online did not go out sometimes, sometimes, just like he liked the program. The hotline was also a disaster. Always occupied and if I come through times, was lifted after 5 ringing and reissued immediately. It took hours (!) Until I had someone on the phone. Ums make it short: After 7 Daytime arrangement and endless and hopeless discussions with the hotline, I have the product returned to you because I simply do not get it to run away. Actually, I would forgive 0 stars. PS I have been working for over 8 years in the IT industry and configure such things are actually my job.
