It's a very good scanner and actively developed still. Sometimes it has issues with the cloud and hangs on an item so I have to start it over, which is a little annoying. It was not compatible with my hard drive when I was running an Insider build, causing system-wide freezing. In that case I had to post at Wilders for help (which I got in a timely way) as email support can be more than 48 hours sometimes. I use it regularly for the right-click context menu to scan downloads and scripts. People complain that it picks up a lot of tracking cookies and calls them "threats" but seriously, you can disable cookie detection in the Settings if it bugs you. I've found that any cookies HitmanPro detects are a valuable thing actually, teaching me to adjust the browser cookie and privacy policy and AdGuard to a stricter level. Cookies can do a lot nowadays-- if HitmanPro detects even one, I'm busy cutting it off at the pass.
I would not pay full price for it, getting it for a sales price, yes. Then I find it worth having on my system. It's mainly a preference thing. Others may prefer EEK or NPE, both of which are free and really good at finding things, maybe too good in NPE's case (fp).
I've been using the free version for years as a second-opinion scanner. By default, it runs a quick scan daily and a full scan monthly. I've seen a few false-positives on new/obscure software, but overall I think it's a valuable tool.
I have been using Hitmanpro for years, sometimes I use the free version, sometimes the paid version. Currently I'm using the paid version on my main machine My other 2 machines, I use the free version.
I use HMP.A on this main desk PC, at times I think it may be unneeded but uses very little resources & I've not found conflicts, when licence expires I will renew - Frequent updates these days.
