I've been called upon recently by many family and friends who were telling me their Avast antivirus was about to expire and my advice to them was simply to re-register, however one user told me the "trial period" was about to expire and I wondered to myself, are Avast about to pull the plug on their freeware version, surely not !!.
So, I went along and surprise surprise, it's the old "press this" and "press that" routine where the developers place a massive button in front of a user saying "get more protection" or something similar and then provide a tiny button saying "or stay with basic protection". Of course, our friends just see the big button so go ahead and press it to (as they say) stay protected. However, what happens here is that a trial version of the Internet Security Suite is downloaded and installed and it's obviously hoped that at the end of this trial the user will then continue to pay for it's use when they receive the "your protection ended" prompt.
Most of the family and friends who had contacted me recently had exactly the same issue and it was this problem they were trying to explain, not the fact that their subscription to the free antivirus was about to subscribe at all. So, again, here we have a security vendor using potentially misleading tactics in the hope of confusing or misleading people into hitting buttons and paying for things when it could be made so much clearer.
Having said that, I've known some of my friends and family to end up with a dozen toolbar's on their browser lol, I can't figure it out
