Keep All Your Softwares Up-to-date:
One of the best ways to protect your PC is to keep all your software up-to-date. Patching over security holes blocks online attackers who like nothing more than exploiting old software flaws to surreptitiously install Trojans and other malware.
The free Secunia Personal Software Inspector makes it easy to find and fix old programs on your PC, even those that lack automatic update features. It scans your computer to find out what versions of what software you have installed, and it reports on which might contain known security holes.
But the excellent app doesn’t stop there. Secunia PSI also provides clickable links to download available patches or program updates, which makes updating most software a snap. Other helpful icons can open the program’s folder, bring up online references for any security advisories, and perform other useful tasks.
Less technical users can opt for a simple interface mode that lists only easy-to-patch software. But it’s worth trying the advanced interface, which displays a wealth of information about your installed software. The latest version includes a handy “Secure Browsing” tab that reports not only on your browser version(s), but also on any plugins, ActiveX controls, Firefox add-ons and other extras.
