Karl used the term "HIPS" [Host-based Intrusion Prevention System] -- it's more accurate but maybe less used nowadays I think, & Zemana themselves say: "System Intrusion Protection", in case anyone takes to Google for more info. The Host-based part means that it's installed on a PC/laptop to help protect it, rather than server-based software protecting the entire network.

These 3 links I think provide info that's good to know... The 1st is their posted compatibility list, the 2nd deals with win8 [note that Microsoft almost requires win8 be updated to win8.1, which is not mentioned], and the 3rd is the manual telling how you use it, what you'll see etc.

A security software package or suite often uses a firewall along with other methods to make you a smaller target -- reduce some of the ways that your system might be attacked. The anti-virus component will use pattern matching, but also some degree of Heuristics, flagging behaviors that *may* indicate mal-ware &/or intrusion. Zemana AntiLogger focuses on heuristic behavior analysis, supplementing your security software. Unfortunately you won't see Zemana AntiLogger compared like anti-virus software at a site like http://www.av-test.org .
Security software will slow you down using a PC or laptop -- when you monitor files and behaviors and compare those to an internal list, using some resources is necessary -- when the goal is to prevent rather than just warn, there will be a delay while that list is checked. That applies both to pattern matching & what I've usually seen called heuristic analysis, because local software does not really use AI [Artificial Intelligence], but is hard-wired to look for certain things, essentially checking what it detects with an internal list. If you use or have used security software you know that there are false positives as well.
It's up to you to decide if the extra protection you might get from Zemana AntiLogger is worth any added delays using Windows. The more extra hardware resources you have, the less you might notice any effects -- a powerful gaming PC might have little to spare in the middle of a demanding game, just as the least powerful laptop might be giving you everything it has in normal use. It's also up to you to decide how you feel about security software you've already installed -- security software comes in different versions at different prices, & you might feel that a company's top of the line product has you more than covered. In real life nothing will protect you 100% -- risk management is deciding how much protection is worth how much cost, in money, time, & effort.
Uninstalling, portability etc...
If someone has physical access to your PC/laptop they might be able to install a hardware device &/or software to monitor & steal whatever info. Otherwise to infect your system they usually have to get you to run a small app, which downloads & installs the working parts of whatever mal-ware. Attempting to partially disable your security software is often part of that process, so security software tries to protect itself, sending roots deep into Windows, while hiding &/or restricting access to its files, folders, & registry entries. That means portable solutions are out for more than scans -- if the USB stick with portable AV software isn't attached when mal-ware's installed it can't detect & subvert it.
Those security measures also make it hard to remove security software -- if it's hard for mal-ware to remove it, it's hard for you too. Many security software companies also make a removal tool because of that -- they allegedly remove everything, but mileage can vary. Zemana does not provide such a tool that I could find. I did see several references to its hidden driver, and read posts asking for help getting rid of leftovers after normal uninstall.
