Reasons Why You Need an Antivirus on your Windows Operating System No Matter How Careful You Are

COMPUTER SECURITY

Whenever antivirus software is mentioned, someone always seems to chime up and say they don’t need an antivirus because they’re careful. This isn’t true. No matter how smart think you are, you can still benefit from an antivirus on Windows.

The idea that antivirus software is only necessary for irresponsible Windows users is a myth, and a dangerous one to spread. In an age where zero-day vulnerabilities are found and sold to organized crime with alarming frequency, even the most careful of users are vulnerable.

Being Smart Only Helps So Much

Many people think that you can only get malware by downloading suspicious files, running unpatched software, visiting the wrong websites, and doing other irresponsible things like having the Java plug-in enabled in your web browser. It’s true – this is how most people pick up malware. But this isn’t the only way malware can spread. You may not be able to protect yourself against zero day threats – vulnerabilities that the bad guys find first. The ones (virus) we don’t know about, which we can’t protect ourselves from. These flaws are corrected as soon as they’re found, but new ones inevitably pop up.

In other words, your computer could be infected just from you visiting a website. Even if you only visit websites you trust, the website itself could be compromised – something that happens with alarming frequency these days.

AN ANTIVIRUS IS THE FINAL LAYER OF PROTECTION

An antivirus is your final layer of protection. If a website uses a security flaw in your browser or a plug-in like Flash to compromise your computer, it will often attempt to install malware – key loggers, Trojans, rootkits, and all sorts of other bad things. These days, malware is the domain of organized crime looking to gather financial information and harness your computer for botnets.

If a zero-day in a piece of software you use does give the bad guys an opportunity to get malware onto your system, an antivirus is your last layer of defense.  It shouldn’t be your only layer of protection, but it is an important one. And there’s no good reason not to run an antivirus on Windows.

Why Wouldn’t You Run an Antivirus?

Some people believe that antivirus software is heavy and slows down your computer. This was certainly true in the past. Older Norton and McAfee antivirus software suites were infamous for slowing down your computer more than actual viruses would. They’re full of notifications and inducements to keep paying for a subscription and buy more expensive security suites, just as adware annoys you with requests to buy products.

This isn’t true anymore. Computers have become so fast that antivirus software doesn’t weigh them down like it used to. There are also more efficient security suites that are lighter on resources. Avast are lightweight antivirus programs created by Avast company. They don’t try to sell you anything at a costly price.

An antivirus program like Avast or AVG is cheap, and won’t noticeably slow down your computer, won’t harass you to buy anything, and doesn’t include an annoying update process (it updates automatically). If it does slow things down, you can use exclusions to exempt certain trusted files from the antivirus scans.

Antiviruses like Avast and AVG are a very low-hassle way to increase your security. There’s no reason not to use them – unless you just want to brag online that you’re too smart for an antivirus.

You Should Still Be Careful

An antivirus is only a single layer of security. No antivirus program is perfect, as all the antivirus tests show nothing catches all malware all of the time. if you don’t exercise caution, you may become infected by malware even if you’re using an antivirus (Of course, performing scans with other antivirus programs may help find malware your antivirus suite can’t find.)

Be careful about the files you download and run, keep your software updated, uninstall vulnerable software like Java, and more – but don’t drop your antivirus defenses completely just because you’re being careful. A zero-day in your browser, a plugin like Flash, or Windows itself could open the door to infection, and an antivirus is your last layer of protection.

Malware isn’t what it used to be – much of it is created by organized crime to capture financial information and other sensitive data. Antivirus software helps you stay ahead of the bad guys by a little bit more and it’s worth using.
