Secunia PSI – PSI_TRAY.EXE
Psi_tray.exe installs with Secunia Personal Software Inspector. The Secunia PSI is a free security tool designed to detectvulnerable andout-dated programs and plug-ins which expose your PC to attacks. Attacks exploiting vulnerable programs and plug-ins may not be blocked by traditional anti-virus programs. The solution to block these kind of attacks is to apply security updates, commonly referred to as patches. Patches are offered free-of-charge by most software vendors, however, finding all these patches is a tedious and time consuming task. Secunia PSI automates this and alerts you when your programs and plug-ins require updating to stay secure. You'll find more information at http://secunia.com/vulnerability_scanning/personal/.
