Best Antivirus Software 2025

Who needs antivirus software?

These days, everybody needs antivirus software.

Computer viruses don’t just come from streaming or downloading movies. Many people think that they can avoid potential threats by making sure they don’t visit certain websites or download certain files.

The truth is computer viruses can make their way onto your computer or any other device in a number of ways. You can pick up viruses and malware simply by checking your email, browsing the web or from putting a USB memory stick into your laptop.

Virus protection is a requisite of having your own personal computer. Luckily for you, there are hundreds of choices of antivirus software – each with its pros and cons. Making a choice between internet security software can be difficult, but that’s what we’re here for!

How antivirus works?

Most antivirus software works on a signature database, monitoring the internet 24 hours a day, 7 days a week. Every time a new virus is reported – it’s indexed, catalogued and added to the software’s database. Once your antivirus software is up-to-date it is equipped to tackle the new virus should it ever reach your device.

How to handle viruses?

You often have three options when faced with a threat on your computer: delete the threat, quarantine it or ignore it. Deleting is almost always the best option, but some viruses make themselves "un-deletable" and quarantining becomes your only option. Your quarantine folder will keep the virus isolated and prevent it from spreading or causing damage to other files. Antivirus can be passive or active – passive requires you to make scheduled or manual virus scans, while active runs in the background; detecting and fighting threats in real-time.

Free VS Paid antivirus software

If you are deciding on a new antivirus software and may want to try a free version, keep in mind that there are pros and cons for both paid and free versions.Using a free antivirus software can cost you more in the long run and most experts suggest that it’s better to use a paid version. Free versions can be great to try a new software or set of features, but will never provide the same level of protection - and your service most certainly won’t include internet security software.

Paid versions of an antivirus software will cover both online and offline activities, permanently delete sensitive digital files and provide extra encryption to protect your most private files from malware like Trojans, worms and ransomware.

A paid antivirus software is especially helpful if you have a PC or device that has already been infected. Many paid versions offer virus removal and cleanup tools, in addition to the highest-quality prevention and detection rates.
