I read the other day that many worms, viruses and trojans tend to exploit to the OS system itself but vulnerabilities in applications. Take Excel for example. A malevolent script propagates via excel macros, which then proceed to corrupt a hug amount of data. To safeguard against this, you need to regularly update your applications. That can be a doozy doing manually considering we have at least 20 applications on a PC. Imagine every application an open window to attack. Your Vista or XP may be well patched (the front door)… but what about these apps?I tried one good solution in the form of Secunia. It’s a free application that does an indepth analysis of installed software, available updates and vulnerabilities. Just one click. Whoosh, you get a list of potential intrusion vulnerabilities.

If you share your PC, this is one heckuva indispensable program. You don’t have to know what your compadres had installed recently (every additional software opens new holes), you just have to run Secunia. In seconds, you’ll know what to patch and keep yourself protected.

If you haven’t already, I strongly urge you keep it in your arsenal.
