  • Default-Deny Protection – Default-Deny protection that is implemented to prevent the entry of suspicious files by default.

  • Auto Sandbox Technology – A virtual environment where suspicious and unknown files are secluded and run to check for any malicious activity without interfering with the normal operations.

  • Containment Technology – Validates and authorizes the programs that are executable and ensures that the processes are run without effecting the regular operations of the system.

  • Host Intrusion Protection System (HIPS) – This feature works on a protocol-based intrusion prevention system, that oversees all the application and program activities that aare processed in the system.

Antivirus software is a type of program designed and developed to protect computers from malware like viruses, computer worms, spyware, botnets, rootkits, keyloggers and such. Antivirus programs function to scan, detect and remove viruses from your computer. There are many versions and types of anti-virus programs that are on the market. However, the prime objective of any antivirus program is to protect computers and remove viruses once detected.
Most antivirus programs incorporate both automated and manual filtering abilities. The programmed scanning process may likewise check the entire hard drive on a day-to-day basis. The manual scanning system enables you to check single documents or even to scan the complete network at whatever point you feel it is necessary.
