What are the currently available antivirus programs?

An antivirus program or software is a kind of software used to detect viruses in the system and protect the computer or network from attacks.

Whenever the virus gets into the system, the antivirus software warns that the users can take necessary action, like deletion or quarantining of the infected file. Cyber-attacks play a vital role and cause huge losses to companies.
