What kind of popups? I haven’t seen any. You might have picked up some spyware/malware. I finally decided to just rely on Microsoft’s Security Essentials and firewall and haven’t had any issues. Was using different Antivirus/Firewall/Spyware software, but decided to go for a simple package about 6 months ago and haven’t had any issues. I still practice safe browsing habits because even a good defense can be overridden by the operator.
There are those “key “ like in your post the word “package” and text enhance ad comes up. Words that when you mouse over they come up with ads that you have won somthing or answer a question. I have popup on and anti spyware.
