define firewall Antivirus and anti-spyware with examples
Answers
Anti-spyware software is a type of program designed to prevent and detect unwanted spyware program installations and to remove those programs if installed. Detection may be either rules-based or based on downloaded definition files that identify currently active spyware programs.
A properly configured firewall can minimize damage caused by spyware by blocking unauthorized access, while antivirus is a software application used for the prevention, detection, and removal of malicious software, including computer viruses, trojan horses, spyware, and adware.
