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.
