Computer Virus

VIRUS refers to Vital Information Resource Under Siege. A Computer virus is nothing but a malicious program that brings damage to the data and applications which exist in computer. As we know that there are different types of viruses, each have its own characteristics. It’s a common problem for everyone who uses Windows and its allied Operating Systems that their PC gets affected by virus frequently unless they use a highly secure Antivirus.

Though we use antivirus software to make our PC free from virus, no anti-virus can assure that its 100% virus proof. So measures may help to make antivirus software better by making regular updates of virus definitions and so on. There are some viruses which disable antivirus software and take the control to itself.

Viruses easily get spread in executable form and through USB drives by means of antorun.inf file. The Windows OS itself cannot withstand to Virus after some extent whereas Linux OS can withstand to virus at greater extent. Linux also cannot be said as Virus proof OS but it cannot be affected by Virus easily, since it’s highly secure. Linux also doesn’t support executable files and modifying some of the core files need administrator permissions. It’s also a notable thing that Viruses are helpful to some extent, such as some spy wares used in some companies to know whether the employee really works but there are lot of disasters because of viruses. Making a system 100% free from virus is highly impossible but some safeguard measures can help us to be secure to some extent!
