What To Look For In An Antivirus For Windows 11?

We can read tons of listicles and reviews about different antiviruses. You need to prepare a checklist while looking at each one of them. Here are a few things to keep in mind:

  • Free Trials
    This comes in handy when looking for premium Windows 11 antivirus. You have to take a test drive and see how it fits your needs. Several leader antivirus apps offer a 7 to 30 days free trial, depending on their pricing.
    Some of them will ask you to put down the payment information to use the premium plan. Few of the others provide no-strings-attached trials with a trimmed-down premium plan.
  • False Positive Record
    We get that it is virtually impossible to catch every virus, malware, or trojan out there.

The antivirus needs to have a reasonable false positive record with respect to its competitors.
  • Impact on your Computer’s Performance

  • Customer Support
    Running into a problem with your antivirus is very common. It shouldn’t put your day in gridlock since all your work is on the computer. Good customer support is of umpteen importance for an antivirus program.
    The customer support staff should be swift and efficient in troubleshooting all the problems of its customers. At a bare minimum, for free antiviruses, there should be extensive support articles for users to brave the storm.
  • Features
    A perfect Windows 11 antivirus for you should have the features that fit the bill for an individual. Every security app offers primary virus and malware protection. What sets them apart is the “extra” they have on the table for the consumers.
    Some antiviruses offer password managers, and a few others offer child locks for restricting online content. You can see what a good fit for your needs is.
