How to avoid virus when searching information from strange websites ?

The following five steps will help you have a safer web browsing experience. This is from Bruce T. Gourley blog.

1. Use a safer web browser, such as Mozilla Firefox. Microsoft Internet Explorer, especially used in conjunction with Microsoft Office products, is much more susceptible to adware, malware and viruses than Firefox, Opera and some other lesser known, but very good, web browsers.

2. Whatever web browser you do choose to use, be certain to download all updates and familiarize yourself with the built-in safe surfing features, and tweak the settings to ensure a high degree of protection. Most web browsers are now able to warn you if you are about to go to a fraudulent site (especially a phishing site) or if a download poses a possible risk. (Note: No web browser is able to identity every fraudulent site or risky download.)

3. Be very careful about downloading any software file off the Internet! Adware, malware and viruses frequently "ride in" atop music, video and other files. As a rule of thumb, do not download anything from the Net unless it is from a trusted source ... and even then be diligent, as some trusted Net companies have utilized adware companies to pitch their products.

4. Use anti-adware, anti-malware and anti-virus software religiously. A number of reputable companies offer security software. While most products require a subscription, some excellent software is still free (at least at this point). Use the top free Anti-Virus and Anti-Spyware software currently available to consumers. I personally recommend a combination of free offerings: SpyBot, Ad-Aware, SpyWareBlaster and AVG Anti-Virus. Together, these four programs will effectively guard against almost all possible intrusions by adware, malware and viruses (phishing, unfortunately, is a bit more complicated). In addition, advanced users should consider using ZoneAlarm, a firewall utility that monitors and filters all Internet activity on your computer. Finally, if you are accessing the Net through a broadband connection, install a router between your computer and your modem; routers act as an external firewall, hiding your computer's identification (IP address, or Internet Protocol address) from would-be intruders.

5. Control who uses your computer. Teenagers especially are frequently unaware that their music and video downloads can be dangerous. In general, assume that anyone other than you using your computer does not know how to prevent adware, malware, virus and phishing. Their lack of knowledge could endanger your identity!
