I went to their website and it showed free on the download button and their buy link says no long accepting payments. I haven’t tried to install it again. Just thought I’d share.
Their forum has seen very few new messages since a few years, and the ones I read were spam... I’ll pass, thanks...
When its website for down for about a day a few days ago, I though there may have been some changes coming. However, the installer for Twister has not been updated since April of 2014. So it appears to have been abandoned.
if i am not mistaken bellgamin was a very active member here who used twister .... he can say what is going on there
At least they are still updating the signatures Virus Definition Update Pack Version: 01/13/2018.13:40
Well, the definitions are kept adequately current, but their engine is 4 years old. Ergo, their program's algorithms must be pretty much out-classed by today's malware. Obviously they have no marketing savvy. Otherwise they could just make a few cosmetic changes to the GUI, name it "Twister 2019", & they might sell a few thousand copies.
