Hundreds of new viruses are created every hour. To counter this, antivirus software developers

                  regularly release updates online, allowing their program to detect the latest threats. Updating
                  your antivirus software can only be done through the Internet, making an Internet connection
                  essential for maintaining protection throughout the day.
                  Eradicating a virus means cleaning a computer of malware. There are several methods for this:

                     Removing the virus code from the infected file.

                     Deleting the infected file.
                     Quarantining the infected file by moving it to a location where it cannot be run.

                     Informing the user about the presence of malware and the actions taken.

                     Isolating all infected files and applications to prevent further spread.
                  Some well-known antivirus programs include Norton, McAfee, Quick Heal, AVG, Symantec,
                  SmartDog, and Kaspersky, etc.

                    Scan  your  files  with  antivirus  software  before  opening  or  downloading  them  from  the
                    Internet. If the antivirus detects a virus, clean the file. If the software can’t clean it, delete
                    the file.



                     FIREWALL


                  The term 'firewall' originally meant a wall built to constrain a fire within a building. On a computer,
                  a firewall is a security system—either software or hardware—that controls the traffic coming in
                  and out of your network based on specific rules. It acts like a gatekeeper, blocking unauthorised
                  access  and  checking  each  data  packet  against  these  rules  to  decide  if  it  should  be  allowed
                  through. A firewall creates a barrier between a secure internal network and an external, less
                  trusted network, like the Internet, by monitoring and controlling incoming and outgoing network

                  traffic based on predetermined security rules.
