Zemana Antilogger not only keeps an eye on your keyboard not to allow spies to log what you type, but it offers extra protection when accessing the bank (virtual keybboard) or having videoconferences.
It's the perfect choice if you want to make sure you are not going to be spied any more.
You only have to install it and it knows what to do. Of course, if you are an advanced user you can configure settings, but default settings are pretty well configured for novice users.
Developers say it starts working where your antivirus give up and we can say it works pretty well.
15-day trial version.
