@bootsy: Read my reply#71 and RejZor reply #72 of page 5. Let me know what you think?
First, I appreciate the fact that you suggested a fix rather than just criticize people who have pointed out the problem.
Before I comment, we are talking about (I assume) not just an old version, but
an old version that AVAST is retiring. A version that will no longer be receiving updated viral databases. B/c (separately?) it sounded like you were trying to make the point AVAST should not make ANY older versions available, and I disagree with that (if that's what you were saying). AVAST understands they will keep more users if they maintain the last x-number of versions.
So as to the versions they retire, before it gets to the point where your suggestion would kick in, it would be nice if AVAST sent a popup alerting the user to the fact that the version of AVAST they are using will be reaching it's end-of-life "in 30 days" (60 would be better for admins, but 30 at least gives them some time) and will no longer be receiving viral updates after that date. That an update will be offered and required in order to remain protected. (edit: IOW to remain protected they need to choose to upgrade... not that AVAST would force it.)
Then in the last 2 weeks or so, an "Update Now" or "Update Later" button would be fine... if someone wanted to use an older version that is still supported, they could always click "Update Later" then uninstall the software at their leisure and install the version they want, manually. (As I certainly would, even if I installed the newest version... I never let a software company or the Web install programs for me.)
Now the question in this hypothetical is, does AVAST care if people choose to be lazy and run an old version that is not getting viral updates until they get around to installing a new AV, whether it be AVAST or a different AV? If AVAST wants to terminate all use of a retired version, they can make it unusable at the end-of-life date,
as long as the original popup states it will no longer function after said date [and AVAST gives the user plenty of notice (min 30 days)]. That's fair, it's their software (esp the free versions), if that's what they want. And the user will have to update through the UI or manually, or look elsewhere for an AV at that point.
If, OTOH AVAST hopes the longer a user sticks with AVAST the greater the chance they will upgrade to it again when they finally get around to upgrading, then after that end-of-life date passes a popup could continue to remind the user they are no longer protected and need to update. A nag. The longer the user sticks with the retired version, the more frequent the nag might appear. That's fair too. And will remind the user their AV is no longer providing adequate protection against new malware.
As for the second post commenting people will just keep clicking Update Later button... an AV is not something users will ignore forever once it is no longer getting viral updates. And that part of it is really up to AVAST. Whether they want to make retired sftw stop functioning or not. As long as they give the user plenty of notice and don't update the user against their will... the user will eventually either click the update button or install something else on their own.
And if AVAST allows the sftw to continue to function and the user does not upgrade, that's on the user. But I can't see too many people continuing to use an AV that is not getting viral updates.
