Three laptops on which the product has been installed, only run the most powerful without problems. One of the laptops (relatively current with 4GB of RAM and i5 processor), for example, since the installation often for a long time can not be addressed.

But particularly troublesome are the hidden configuration options: time fast the firewall or antivirus software is off for certain actions only after endless clicks in seemingly randomly arranged menu possible. Information about the found vulnerabilities or alleged pest finds do not exist. Exclude certain file types (movies, music, etc.) from the access scan: impossible! Other features such as SiteAdvisor or AntiSpam should be turned off right after the installation, if you want to protect his nerves, otherwise you again feels transported back to the days of 54k modems and each mail must manually pull out of the spam folder (if it is not even completely gone ...)
