SpyShelter Personal Free is a freeware anti-keylogger and anti-malware tool. The free version is for personal use only, but other than that comes with a impressively comprehensive set of functions for locking down your computer.
As well as monitoring for key-loggers and trojans, the freeware automatically creates program whitelists, and you can also manually set a list of restricted programs which cannot alter the registry et al. I generally tend to find these ultra low level security programs a little intimidating, but it’s nice to see with this one that there’s lots of scope for tweaking and customising settings to prevent glitches or unwanted lockdowns.
Nevertheless it would probably be better to proceed with caution in terms of setting up restriction lists and the like, until you’re sure what locks what. Despite the caveats, if you’re worried about protecting your computer then this is one tool you might like to check out first.
SpyShelter can protect you against attacks that happen even when you do ordinary computer tasks like: typing into your computer, getting screenshots, opening files, and visiting sites. The SpyShelter monitors vulnerable and weak spots in your computer system to ensure that even the most advanced keyloggers are shut down even before these can launch a single dangerous attack against your computer.
