Antivirus and their function.

Antivirus software scans program using selected chunk of data from its database. If it gets a code that resembles to that of a malware stored in its database then that code is flagged as malware. Now this is either isolated or deleted
The detecting based anti-virus applications dominate the security industry over time. But due to rise in cybercrimes and criminal activities across the internet, these applications have not been very effective against the dangers. In the current times hackers are well equipped with efficient analysis workstations and penetration applications to check whether new malware software’s are being detected or not.

Features of Antivirus Software
Background Scanning – the anti-virus scans the applications which are present in system, when they are opened in their backend state. This process is called an on-access scanning. This assures that the system is safe from all sought of malware attacks

Complete System Scans. these scans are not much needed if there is on hand access feature on the system.it is well used if the anti-virus is installed for the first time or the security of the system is not updated for long time .this is implemented to ensure that there are no malware hiding in the most difficult locations and deep behind the codes of the system. Full framework scans are vital to scan your contaminated system

Virus Definitions - Antivirus software codes are based on the definitions to differentiate a virus from a genuine file and a malware. This the vital step to check on new virus definitions. The virus definitions clears of the of the marks of any codes which are considered as hazard in the system code.in the scenario of virus definition finds a file with marks of malware that matches accordingly, then that file is immediately terminated from execution and is isolated. The antivirus software runs through the malware, analyses it, and sends to lab to find out the origin and purpose of the malware in the system
