Security Analyzer is a simple tool that will quickly issue a report on your PC's security status.
Just launch the program and it will check to see if your system is being protected by a firewall, or an antivirus tool. It will also report on your Windows update status, and allow you to turn on User Account Control and Network Access Protection (if they're currently turned off).
And at the head of the report will be an overall rating for your system security, which if all is well should be highlighted by a reassuring green tick.

This portable tool provides a quick and easy way to spot any major security issues with a PC
