When it comes to computer security, there are so many things to think about. You need antivirus software, anti-spyware programs and a firewall, but if you think security ends there, you're sadly mistaken.
The Microsoft Baseline Security Analyzer will help your assess your computer's security. It will make sure Windows and Office are updated with all the necessary security patches.
You can also learn about other security issues that you might otherwise overlook. For example, it will check for multiple administrator accounts to see if other users have more control over the machine than they should.
And what about your account password? If your password is weak, others might be able to access your account. The Microsoft Baseline Security Analyzer will alert you if account passwords aren't strong enough.
Microsoft Baseline Security Analyzer gives you a detailed assessment that will be quite lengthy. Take the time to read it thoroughly and fix any problems listed. It is another tool in your arsenal to protect your machine.
Warning: This is a tool geared for advance users. Following some of its recommendations could break other programs or Windows if done incorrectly. Before you make any changes to your system, be sure you understand what you are doing.
