However, I can’t open these programs because a window comes up saying “Application cannot be executed. The file avg+free_stb_all_9_40_cnet.exe is infected. Do you want to activate your antivirus software now?”
Yes – No
i click no, but if i click yes internet explorer opens up with this antivirus soft page with the url: http://av-protect.com/purchase?r=57.8.

my guess is that this isn’t safe. maybe it is, but i have to purchase this. i want to use the programs that are recommended (such as AVG and spybot), but it isn’t letting me. What can I do to fix this? Any help would be appreciated.
