If you’re worried about suspicious programs logging the activity on your computer, SpyShelter Premium (reviewed here) offers a wide range of protection components to fend them off.
The application is regularly priced at $19.46/€15 (VAT not included) for a one-year license, but for a period of three days, you can get it with a huge discount, for only $8 / €5 (VAT not included). This can be achieved by punching in the SOFTPEDIA coupon code when purchasing the application.
The logging activities that SpyShelter Premium can defend you against include keystroke logging, surreptitious screen captures, audio logging, clipboard content capture and webcam logging.
Apart from this, SpyShelter Premium also includes HIPS technology to detect suspicious actions in sensitive system areas and keystroke encryption, which can scramble the key input for all processes, except for the ones currently in focus.
It is pretty easy to work with, even for the average and beginner users. At the same time, more experienced users can enjoy more complicated functionality such as creating a list of applications that should run with lower privileges and define the areas they have access to.
Note: The developer does not guarantee full product support to users buying a license via any kind of promotion.
