In “How to Secure Your Windows PC – Part 1“, we established that Windows PCs are often targeted because of their large market share and that the brand of your computer makes no difference because viruses, spyware and malware occur at the software level.
To protect your Windows computer, the first and best rule of protection is to use your head and be pro-active in your browsing and clicking habits. This typically means two things:
- Only visit websites that you know can be trusted
- Use caution when clicking on links in e-mail that are unsolicited
Let’s look a little closer at #1:
How do you know which websites can be trusted? There is a difficult tension here – if you visit only the sites you already know, there are many useful and informational websites out there that you will miss in an effort to be cautiuos. But, if you go out willy-nilly and click on every site that comes up in the search results, your computer will get infected with malicious software sooner or later.
So the answer lies somewhere in between. More experienced users can take a little more liberty in clicking on unknown sites, but naive or less experienced users will need to be more careful when visiting unknown websites.
The truth is that malicious websites will do their best to look like a legitimate, reputable website. But these same sites will do damage to your computer that can be difficult to recover from.
Let’s look a little closer at #2:
E-mail is also a popular way to direct people to websites that are harmful not only to your computer, but to your privacy. If you get an e-mail from a financial institution, never click on the link in the e-mail. Instead, go to your browser to access the institution’s site directly.
It is very possible that the legitimate-looking e-mail you just received will direct you to a “phishing” site that will extract your login information and allow someone else to access your accounts and information.
In Part 3, we’ll consider two types of software that can help protect your computer from viruses and spyware.
