Sometimes I trade in a semi-public area and wanted to know if anyone knew of a software that allows me to have a second-screen saver type of security system in place (that also requires a password). In other words, I have my screen saver programmed to activate if I'm not using my PC for 30 minutes. Then I have to key in my password to activate my screen. Is there another software of system I could have in place to double my security? I want to keep my screen information hacker-free and am was wondering if anyone knew of such a system? Thank you!
