A year or two ago I downloaded a free version of AdAware, an anti-virus software application. It was a free trial for six months or maybe a year.
Anyway, as the expiration of the free trial approached, I got pop-ups on my computer reminding me that my subscription would be expiring in 4 weeks, then 3, then 2, then 1. Then it went to six days, five, four, three, etc. Then it went to hours and minutes.
Once it expired, I got reminders that it had expired. Then I got offers to renew. This went on for two weeks after expiration.
Apparently the developers put in a "he's not giving in" feature, because I now have AdAware for free again.
It works well, but the annoying thing about programs to block pop-up ads and other annoyances is that they have their own annoying pop-ups, even if you pay for them.
Okay, back to my other curmudgeonly activities.
