Good anti-virus software at an affordable price

So far, I am really very happy with the program. Especially the SiteAdvisor, which warns of dangerous websites seems to work very well. The only thing I would criticize is the extended polling time a lot of e-mails as these are checked for spam. Unfortunately, this time will be reduced not even after switching off this function. Previously I had Avira Internet Security installed, but McAfee Internet Security 2015 makes me whole, a better impression.
I highly recommend the software.
