PREVENTING MALWARE INFECTIONS

          Here are some measures that you should follow to minimise the risk of malware infection on your
          computer system:
             •  Install an antivirus program and scan your computer regularly for malware.
             •  Update your antivirus software regularly.
             •  Use software from trusted sources only and scan it before
                installing.
             •  Always open email attachments after scanning them.
             •  Scan files downloaded from the Internet, transferred through
                a network, or copied from removable media.
             •  Install  a  firewall  program  to  filter  incoming  and  outgoing
                messages on a network.
             •   Adjust  the  security  settings  in  your  browser  to  ensure
                maximum protection from malware.
             •  Never use pirated software.
             •  Take regular backups of your files on a separate media.
             •  Do not reveal personal or financial information on a network.

                Firewall is a software, device, or computer that scans each incoming as well as outgoing message on a
                network and blocks those that do not meet the specified security criteria.



          ANTIVIRUS SOFTWARE
          An Antivirus software is a utility software designed to protect the computer from viruses and other
          malicious software. It scans the internal memory, hard disk and external media attached to the computer
          to identify, isolate and eliminate viruses. It also examines the incoming files for viruses as the computer
          receives them.

          Some popular antivirus software are Quick Heal Total Security, Norton antivirus, McAfee antivirus, and
          Avira antivirus.

                A virus signature is a continuous sequence of bytes that is common for a
                certain malware sample. That means it’s contained within the malware or
                the infected file and not in unaffected files. A virus database contains the
                virus signatures of all known viruses and signatures and uses it to scan the
                computer system for malware.
