can anyone suggest one and tell me if they actually work?

thanks

 

eblaster is great, and works a treat

captures everything and emails you the whole lot of keystrokes, websites, emails, chatlogs

 

007 Starr Commander used to be very effective

 

They certainly work

Used them in USB seeding experiments we carried out for a few customers. Encode key logger onto a number of cheap USB sticks, randomly drop them outside the head office - wait a few hours for someone to pick one up, take it into the office and plug it in....

A search on Google will reveal loads - just be careful about the environment you are using them in. if this is something to do with work, then you must tell your staff that their PC activity could be monitored - you are on very sticky ground using things like this without permission.
