I am curious to hear from people regarding the longest license time periods they are comfortable purchasing for an anti-virus or anti-malware product. I see some people on this and other forums who buy licenses that last five and even more years. The longest license I have ever been comfortable buying is two years. It always seems like something goes wrong with the product on my computer, or the company sells to someone else or goes bankrupt, or I just get tired of it and switch to something else. Buying a long license doesn't seem to be such a great value in those cases. So, I am wondering what is the longest license you ever had or the longest you would be comfortable purchasing? Also, I am not counting life time licenses that one can sometimes get on a ridiculous deal or as a giveaway. I have two lifetime MBAM licenses that I think I got for $25 a piece a few years back. Of course, I am not running those in real time at the moment given MBAM's problems ... sort of proving the point of my question in the first place. What good is a lifetime license if the product goes downhill enough that you don't want to use it. Thanks!
