Best AI Antivirus Software in 2025

Antivirus software, also known as anti-malware software, scans your computer's memory or files for patterns that indicate malware. It looks for patterns based on the signatures of known malware.

After installing antivirus software, it is advisable to perform periodic computer scanning. The majority of antivirus programs may be set up to automatically scan folders or files and to prompt you to run thorough scans on a predetermined schedule.

The reason behind not using more than one antivirus is because installing multiple antivirus programs can cause problems like system freezing and data loss.

Generally, you don't need to do anything as the security software will clean the infection for you. If unwanted software has been found, you may be asked to choose what to do next.

Free antivirus subscriptions usually have some limits compared to paid versions, such as on the amount of devices connected or the types of threats detected.
