Level 42
are you using the free version of Heimdal or the pro version? I used it for a while but found I did not need it with my current config.
Pro. Despite my exceptionally strong security, I feel Heimdal still offers several benefits. It's one of the best DNS hijacking prevention tools. It speeds cache resolution on DNS resolver requests, it keeps my apps updated, and it's blacklist is sourced from a lot of darkweb forums so it finds stuff most other web filtration misses.

Once Heimdal started offering lifetime licenses I jumped on it.


Level 1
I wouldn't just get a lifetime license of any company irrespective of the price, if I have ever experienced their free trial or whatever, I'll still have the surety.
