Does not for me I have had zonealarm 6.5 all along and never had problems with anydvd. I do not have anydvd set to autostart and I do not have it checked to check for new updates but when I have loaded new one it is set for these and works then. I alway uncheck the autostart and the new updates since I do not want things running in the background that I do not need all the time and I only want programs going to sites when I let them.

My computers has only zonealarm running at startup and I even went to zonealarm and stopped 99 percent of the things that it sets to access the internet. Sure makes my two computer run faster,burn dvds faster and work faster on the internet.
