Do you need antivirus software on your PC?

If you’re not sure of the answer to that question, then the short answer is yes. The longer answer is that security software is only one piece of what should be a simple, straightforward, and approach to your PC’s health. I’ll outline my recommendations in this post. If you’re visiting the family over the holidays, you might want to take my list along with you.
•Antivirus software is one layer among several. Depending on the type of threat, it can be very helpful, even if you consider yourself an expert PC user. But it is not a magic bullet, and it is no replacement for a well-rounded approach to security.
•No antivirus software is perfect. It is literally impossible for any security product to identify every possible threat, especially when malware writers are constantly updating their products to avoid detection. Most of the leading antivirus programs can identify and block the overwhelming majority of threats you’re likely to encounter online. The fact that they can’t reach 100% protection is why security software is only one part of a layered security strategy.
•It’s not just Windows that needs patching. Some of the most effective malware vectors these days are coming through vulnerabilities in products like Adobe Flash and Reader, in the Java runtime, and in Microsoft Office. In most cases, the vulnerabilities were patched quickly by the software maker, but if you didn’t apply that update, you remain vulnerable. Ironically, most of these exploited programs are cross-platform; in theory, malware authors can add code to their PDF or Java exploits that target Macs or Linux PCs. So far, they haven’t done that.
