A computer without anti-virus software installed is exposed to threats from the internet. Malware is becoming increasingly difficult to detect, and thus it is important to install efficient anti-virus to ensure that your computer is protected. An anti-virus software will scan all the files stored on your computer for any malicious files. This may include manual, automatic, or scheduled scans. The computer is also vulnerable to threats from external drives like USB, and anti-virus software will detect such external devices as well. The anti-virus can remove all such threats and the computer can function properly. It will also periodically indicate the health of your computer.

Here are the top anti-virus software options that you can consider in 2021.

Bitdefender
This is the best anti-virus software for the best all-around protection, which is especially true for the paid version of the software. It provides excellent ransomware detection, provides password manager, and has a “Do Not Track” option for more privacy. There are frequent updates that one can expect when one has taken a subscription to Bitdefender. Bitdefender Plus is the basic offering from the company, which is ideal for home use. Some of the other benefits of Bitdefender include monitoring online purchases as well as other web-based purchases. The software is available for Mac, Android, Windows, and iOS.
