In spite of a recent effort to improve the performance and detection rates in Windows Defender, Microsoft’s anti-malware tool is still not very good at its job. According to the latest tests, it’s downright lousy.
The latest round of tests performed by German institute AV-TEST, one of the most respected and regarded malware testing shops, show that Microsoft Security Essentials and Windows Malicious Software Removal Tool fared the poorest in removing an existing infection.
For the longest time, Microsoft’s antivirus programs have brought up the rear in tests, usually ranking near or in dead last. But recent tests from two respected antivirus testers show Microsoft has greatly improved its antivirus product and in a very short time.

You work hard to protect your PC from the malicious thugs of our digital world. You keep your antivirus program up to date. You avoid questionable Web sites. You don’t open suspicious email attachments. You keep Java, Flash, and Adobe Reader up-to-date–or better yet, you learn to live without them.

Obviously, you need to scan the computer and remove the malware. Here’s a methodical approach that you can use to determine what the problem is, how to scan, and what to do afterward to protect the PC from future invasions.
