These ‘anti virus programs’ are like other computer programs. Each virus has a special way of recognizing it. The methods of dentification of viruses that have been previously detected are recorded in these ‘anti virus programs‘ and if any computer indicates the presence of any of these pre-recorded identification marks, then it ‘Anti virus programs’ easily find that virus in the computer.
Each virus has its own specific workspace, that is, each virus has a certain type of files or data that it will damage. Once a virus is detected, anti-virus programs not only remove that virus from the computer, but also, depending on their functions, the damaged data or files, sometimes completely and sometimes partially Correctly correct.
What Happens With An Anti Virus Program?
Anti virus programs also have a system to test many such viruses based on the structure of the virus, about which there is no information recorded in the ‘anti virus program’. Such ‘anti virus programs’ are called ‘smart anti virus programs’.

Usually, many new viruses are being created almost every month, for which each AVP making company, from time to time upgrade their AVP. Some companies do the next few upgrades free of charge to their AVP users and some companies take the old AVP from the customer and give the new upgraded AVP to the customer.
