Sorry if I asked this question but cannot find my way back to the same forum!  And your emails have no provision to reply!
I get a pop-up in the mornings on the bottom right of screen that says I am out of date, and to click to update. This is suspicious because I updated from your website and installed the latest version. (2015.0.5645)  yesterday. I clicked the pop-up only to access their 'more information'. Which says I will update to Version 3???
On their link it says the cerificate expired on January. 2015.
I will send a screen shot next time it appears.
I am afraid to trust this AVG pop-up.
Sorry if this is duplicate but your site wants me to reset password every time I try to log in!
Thanks
