AVG is a great product. And Grisoft has done a wonderful service by offering a free version for all these years.
They have recently resorted to WinFixer-like marketing tactics. Evey other day, when AVG updates itself, my browser opens to an ad for AVG.
The first time it happened it scared the crap outta me because I didn't touch anything that should have opened my browser. I waited, holding my breath, to see what evil thing was going to load, to give me some clue as to what had infected my pc so I could remove it. I was quite surprised to see an ad for AVG.
It's not like AVG hasn't opened a window with an ad for their full product before, just this time they decided to use the browser to do it. They used to use their own application to popup the ads.
Now before you decide to flame me for bashing a great product from a company that has been kind enough to give away a free version, consider this:
On a newer, faster machine...this is just an annoyance. You can just close the window...no harm done.
That being said, there is another issue that isn't just a mere user annoyance...
I have always liked how light AVG was and how well it ran on older low end machines without causing stability problems...liked it enough to publicly endorse it
I am going to have to revise my endorsement for AVG for older slower PC's, due to the fact that many of them can't handle having more than 1 or 2 browser windows open at a time.
If AVG is going to open browser windows this frequently, this will cause problems on those PC's when their owners already have browser windows open.
I can't endorse a product that has a known issue that has a high potential to make your machine unstable every other day when it's updating. I can't endorse a product that has a high chance of causing your machine to lock up in the middle of you doing something important, leading you to lose whatever you were working on.
