Secure your browser with NoScript
A popular way for nasty people to compromise your computer and infect you with malware and viruses is to embed malicious code into websites. Their aim then is to get unsuspecting victims to visit the website, and so this code is downloaded to your computer via your website browser (such as Internet explorer of firefox). Normal website code, such as HTML and CSS, is largely harmless for this purpose but other languages such as javascript, directX and flash may not be as friendly when used in this manner. The logical solution to this problem is never visit a website that you dont trust, but what if you do?
A highly recommended way to help prevent this sort of attack from happening is using a plug-in for the web browser firefox called ‘NoScript’. What this plugin does is block this type of code from downloading and running on your web browser by default. If you do visit a website that uses these features, and you trust them, then you have the ability to temporarily allow the website or add it to an ‘allowed’ list for future reference.
NoScript also has more additional features (including cross-site scripting protection), which will make you more secure when browsing the Internet. I would consider NoScript a Must have!
