What is an Antivirus Software?
Antivirus software is an application created to block, detect, and remove software viruses and other malicious software like worms, trojans, adware, etc. An antivirus application scans files, directories, or the whole system/device for malicious programs or files. Any malicious code detected would be notified to the user, and when asked to clean, the antivirus would clean it. An antivirus keeps the system free of malware and prevents data theft and severe damage.
Antivirus software also prevents the system from slowing down due to malware infection. Antivirus software also provides regular automatic database updates to keep your virus definition up-to-date to protect from new infections. An antivirus software thus improves system performance on the whole.
