I have bought three products from Systweak's, Advanced Vista Optimizer, Advanced System Protection, Advanced System Optimizer. All three seemed to function tell I noticed my desk top icons disappearing and having to re-load Adobe Flash every time I did an optimize. At first Systweak's answered all e-mail that was sent to tech tell I started questioning their software code and who was writing the software.. I have had to re-download the above software's at least 4 times. Systweak's answer to a problem is a link to a better version of the software, All-n-All it might fix the bugs you complained about, But then you are dealing with a whole new problem.. In 15+ years of computer work, I have never had to deal with software that is infested with bugs; Ok, , I forgot Micro$oft.. Back to the issue, Systweak's has not answered my email since I p----- them off questioning the writers of the software, And the "will pay $ for reviews" I just want to warn other of this software, And to stay away from what seems to be BATA being sold as A grade..
