Update not working

I can only warn against purchasing this product: The automatic update of the virus database rarely works, and if you are not careful or updated manually, you are unprotected road. And the best part: The problems are known at Kaspersky! I have contacted the service several times and get an answer in each case also after a very long wait time (up to several weeks). Remedy has but not yield. Recently I received a multi-page statement as I do with a previously downzuloadenden patch delete the program first and then reinstall it. Absolutely unacceptable! Mind you: I am working
Win7 system with a modern and popular Office programs, so no extras, which could push this failure of the program in the shoes.
