Use this guide to learn how to select antivirus software and what features and subscription will work best for you. You’ll also find useful tips for testing an antivirus application, finding the best prices and running the software effectively.

Top Tips:

  • Keep the software set to update automatically, so you always have the best protection.
  • Keep an eye out for reduced prices, especially later in the year.
  • Use a free trial to determine if the antivirus software is easy to use or slows your system down.

How Does Antivirus Software Work?

Antivirus software remains a must-have for PCs, Macs and mobile devices. The software continually monitors these systems to identify and block viruses, malware, ransomware, Trojans and other threats before your computer or data are damaged. Antivirus software also works while you are online to keep you from entering malicious websites and stops you from opening infected email attachments.

Antivirus software should detect and remove viruses in real time as well as scan your system for viruses on command. A virus is unlikely to get past real-time protection. However, you want your software to be able to remove any threats if you suspect your computer is compromised.

If your antivirus software finds a hostile program or other suspicious activity on your PC or Mac, it will either quarantine the offender or remove it entirely. You will likely be able to tell the software in the setting whether it should perform these actions immediately or ask you to decide what to do.

How to Choose Antivirus Software

Malware infections and viruses nearly doubled in the past five years. Fortunately, there are many excellent antivirus software choices, and most of them are very reliable. But it can be challenging to narrow down your options. Here are some tips for selecting the best antivirus software for your Mac, PC, Android or iOS devices.

Use a Free Trial

The only way to know if antivirus software will work well on your device or computer is to try it. All but one of our antivirus selections has a free trial, but offers a 60-day refund for any reason. Use the trial period to determine if the software is easy to use and settings are understandable.

Be on the Lookout for Additional Costs

Many antivirus software companies try to sell additional services, like PC tune-ups or online storage at the time you buy the software. Consider these services carefully as you’re unlikely to need them immediately and can add them later if you change your mind.

Get Public Wi-Fi Protection

Accessing Wi-Fi at just about any cafe, restaurant or other retail establishment is convenient, even necessary for some people. Consider buying antivirus software that includes a VPN, which is a virtual private network. When you’re on public Wi-Fi, strangers could capture your private information as you use the internet. A VPN puts a stop to that, and some antivirus software includes this feature.

Antivirus Subscriptions

All antivirus software offers an annual subscription, and some give customers a deal for signing up for three years. Most antivirus software companies let you pay from month-to-month. These payments work if you’re uncomfortable making a long-term commitment or can’t afford an extended subscription. Unless your antivirus software is free, you need a subscription to keep the software effective against the latest threats.

Multiple Device Antivirus Protection

Consider how many licenses an antivirus software includes if you have a family or you use multiple devices. Subscriptions commonly cover from three to unlimited devices, and the right subscription can offer substantial savings over individual installations.

Antivirus Tech Support Considerations

The price of most antivirus software includes the cost of tech support. However, some companies charge for support, especially if it involves a technician providing remote assistance. Be clear on how support works to know if you’re comfortable with the arrangement.

It makes sense that antivirus software would include support at any time of day or night. However, there’s at least one cybersecurity company with support only during the day. Today’s antivirus software is so easy to install and use that you probably will never need help. But, if you do need assistance, you’ll be relieved to have someone to call, email or chat with 24/7 every day of the year.

It can save a lot of frustration if an antivirus support representative is located in your country. Reps who speak your language fluently and clearly can help you solve problems sooner. Try to find out if you’ll be able to communicate effectively should you require assistance.

Pre-installed Antivirus Software

Your computer or mobile device may have come with antivirus software pre-installed. If this software or app seems to be working well and your system isn’t running slowly, you should probably keep using it. Once the free trial is up, you’ll know what the cost is to continue using the software.

If the cost seems high or your computer is bogged down, you have options. Take a look at the current prices for our top antivirus software picks and make use of free trials or month-to-month subscriptions to test the software. Antivirus software should run practically undetected.

How to Try a Different Antivirus Software

The first antivirus software you try may work perfectly. But if it leaves something to be desired, you can try others. Uninstall your current antivirus software completely and restart your device before you activate the new title.

Click around the new software and dashboard to see if it’s easy to find the settings. Does the information on the panel make sense to you? Use the software for a few days to see if it slows your computer while you are using it.

Frequently Asked Questions about Antivirus Software

Can I run two antivirus software packages at once on my computer?

When it comes to antivirus software, you’ll have to choose one title. Running two antivirus services doesn’t increase your protection. Doing so can cause conflicts on your computer, tablet or other device, making it unusable or leave you unprotected from malware.

Why does one antivirus software’s deluxe version have the same features as a competitor’s ultimate or premium version?

Versions are supposed to make choosing software easier, but one company’s deluxe can be another’s ultimate package. To compare antivirus software side by side, make a chart with a column for each title. Find the version that would best suit your need for the first title, then list the features. Do the same for the next antivirus software you’re considering.

Will antivirus software slow me down when I play computer games?

Antivirus software could cramp your gaming experience. If you’re a gamer, look for antivirus software that offers a gaming mode to bypass this issue.

What does it mean when an antivirus software runs in the cloud?

The best antivirus software runs in the cloud, which speeds up daily updates significantly. Virus signature updates go to a web-based tool instead of directly to your computer. The tool scans your computer for malware and other threats, so there are no hefty, time-consuming updates over several minutes each day.

Does any organization or company test antivirus software?

There are a few companies that test antivirus software to ensure that it’s effective against threats and that it’s preforming efficiently. AV-Test is one of those organizations that runs simulated malware attacks to check and rate antivirus software.
