There are different views on Zemana Anti-Logger here is one review by Raymond cc web site comparing Zemana.....Spy Shelter and Data Guard this review was done 8 months ago but interesting...... https://www.raymond....pture-software/
You can search the web there are numerous reviews on Zemana. I have used Zemana and found it to be adequate..... currently I am running SpyShelter which I feel has more comprehensive protection especially is has System Defense guard that acts as a Host Intrusion Prevention System (HIPS) to protect critical areas from code injection such as memory and the registry.
The bottom line your choice: Zemana is a good choice.... or try another....and compare for yourself.......
