Windows Security may be one of these "Windows 7 Security 2011" rogue anti-virus scams that are circulating, (there are many variants), and if so, follow the guidance and links in this forum thread post here;

AVG is good, but I don't know if I can say the same for PC Doctor. It is not one I am aware of, and is not recommended in these forums.
In my view you would do better to uninstall that and install the two free versions of Malwarebytes Anti-malware and SUPERAntiSpyware.
I hope that helps.
I keep getting this error almost every few minutes about Windows Security and making sure I know that websites are putting cookies onto my computer. I have to press Yes or No and even if I press either one they continually pop back up. I am soooooooooooo frustrated and unsure of what to do. I have virus protection in the form of AVG and PC Doctor too. I am not sure why this started happening. I tried a system restore to an earlier date but it still happens. How do I get this thing to stop popping up when I am on the internet? It's driving me insane!!!
