Secunia, the leading vulnerability intelligence provider in the world, has provided one of the best free tools for securing a computer. this tool, called the Secunia PSI is a free security tool designed with the sole purpose of helping to secure your computer against vulnerabilities in programs.

It will scan your computer, rather quickly I might add, for programs that have known security vulnerabilities. It will then provide you with options fixing the problem..

Keeping the programs on your computer patched for security vulnerabilities is a very important proactive means of keeping your computer secure, and the Secunia PSI is a tremendous help in the regard. We have added it to our standard set of security tools, and run it on all computers that we repair or maintain.

We highly recommend it.
