A few things I know about Comodo Internet Security, correct me I'm mistaken.
Virtual Kiosk provides a Logger-free environment that is safe for inputting sensitive data, online and offline.
Alternatively, you can utilise Defense+ (HIPS) to provide Anti-Logging capabilities. Do you use HIPS-component?
If the answer above is No, Zemana Anti-Logger Free provides that protection. It can be installed on both Windows 32-bit and 64-bit, however a few programs may not be supported. No intrusive pop-ups or HIPS-like prompts.
SpyShelter Free is only available for Windows 32-bit, and you'll have to pay to be able use on Windows 64-bit.
KeyScrambler is another option, but it didn't work too well on Windows 32-bit, and I'm not sure if it's something I'd recommend -regarding v3.
