Which is your avast version?
Is this pop-up the upgrade from 4 to 5 version?
Why didn't you upgrade yet? It was released in January. The support of version 4 will end by December of this year.
How would one be able to tell?... the pop-up looks like many "hijack" popups, doesn't state you should visit the website, doesn't mention 5.0 (or 4.8 ), offers you links that I'm not going to click on a "marketing" pop-up that looks like that.
I had to do an internet search to find this forum to find out that it might be due to a legit prompting to upgrade to 5.0 from 4.8.
All in all I have to agree this pop-up is annoying and misses the mark. I would have likely upgraded weeks ago had they simply used the words: "go to the regular avast website
www.avast.com and check out information on 5.0". For the record, this is not the usual green slide up dialog that avast has used but a rather obnoxious pop-up that covers the entire screen that is heavy on the "marketese" but light on the information front. This is not the technique an antivirus firm I expect to elicit upgrades since it emulates the very thing that I seek to avoid on my machine... an obnoxious pop-up that comes out of nowhere... doesn't match expectations of any application I've installed... and repeatedly pops up when it is unwanted at random intervals.
For the record... I've upgraded now (although I had to re-register which was another annoying attribute of this upgrade). ;-)
We'll see...
