Question

What’s the difference between free and paid antivirus?

There are a few noteworthy free antivirus programs on the Internet. Quite a few more are gimmicky. A few have even encountered lawsuits because of false promises they made.

We’re not suggesting you stay clear of all virus protection that is free (as some have been reviewed favorably here), but you should definitely exercise warning.

In general, paid subscriptions to the top antivirus software is the best route to take if you are truly serious about protecting your computer than you should go with the best.

Due to the highly technological society we live in, online predators are very active and constantly trying to stay ahead of the curve compared to what virus protection programs can guarantee.

Paid subscriptions are simply more comprehensive and ahead of th than free offerings.

System Performance and Scan Time

Probably the most important aspect of any software, antivirus or not, is how it runs on your computer. You could have the most expensive and advanced security suite in the world, but it would be completely useless if it didn’t run well.

A good antivirus software is unobtrusive. It should run in the background and not interfere with all of things you do with your computer. It should work to clean your computer up and make it operate faster – not slow it down.

On top of this, good virus removal software should have a reasonable scan time. Running a system scan means checking all of the files on your computer for a virus.

Because most computers contain thousands of files, it can take even the best antivirus software scanner quite some time to run to completion.

Good software is comprehensive and should also give you the option to run a quick scan in the event you think you may have come across a suspicious file and need to know right away.

Virus Detection Capability

When an virus removal software scans your computer for a virus, it is comparing each file on your computer to the files it contains on its signature database.

A signature database is a collection of signature markings associated with common viruses. Like a fingerprint, each virus has its own unique signature that identifies it.

If one of your files has one of these signatures, a system scan will identify it as a virus. Good antivirus software has an extensive signature database that contains all the world’s most common threats, but the database must also be able to evolve as threats change.
