extremly disapointed about this product, I have renew 5 license for 3 years and for sure is last time when I did it. ...even I have available license for mobile, I can not use them, because there is no option to add the activation code on Avira Security for Android, the only option is to pay for the license.......and this is just one of the problem I have met with license activation.

My name : Kai Chen
According to Mr. Sidney Martins answered to the problem of Mr. james plaistow. I have tried all three suggestions, still got negative. My system is Windows XP sp3. and I've using Avira Free for many years.
Try I. negative.
Try II. negative.
(In my computer there is no proxy address being used, proxy address block is empty. And all check blocks of both Automatic configuration and Proxy server are unchecked.
Therefor I check Avera Proxy server to 'Don't use a proxy server.' )
Try III. negative.
(Add following 4 items - fact.exe ; update.ex. ; sched.exe and Start Avira Free Antivirus to exception list of firewall)
Do you have any further suggestions?
