Windows has three main threats: spyware, viruses and hackers. Spyware and viruses are much more of a concern then the latter. Spyware, sometimes called adware, is software written by companies to track users on their computer. Sometimes this is fairly harmless, their just collecting information about the sites you visit. Other times this is very dangerous, they could be collecting passwords or financial information. Viruses are simply malicious programs that people install, usually from email attachments. Most recent viruses either use your computer to send out spam or to attack companies’ web servers. The last concern is hackers. For the most part you need a firewall.
Steps to make your computer safe:
1) Update your computer. Microsoft is always releasing bug fixes to windows. About once a week you should: click start -> Windows Update. You really need to install all of the updates not just the critical ones.
2) Install an Anti-Virus and update it. Most of you probably have an Ant-Virus, but not all of you are updating it (you know who you are). Please update it and run a complete scan once a week. If you do not have an Anti-Virus, please go to http://free.grisoft.com.
3) Install Anti-spyware. You can download Adaware for free here: http://www.lavasoft.de/. Please update Adaware and scan your computer once a week.
4) Don’t open executable e-mail attachments. All Office documents are executable attachments, all Adobe and AutoDesk files are not. If you are unsure of an extension look it up at http://www.filext.com.
5) Stop using Internet Explorer. Most spyware is written for Internet Explorer, so you can avoid this entire problem by not using the dominant browser. My recommendation would be Firefox, which is free and can be downloaded at http://www.getfirefox.com.
So with a little effort, you can remain safe using Windows.
