    What are the different ways by which virus can enter to computer?

    What are the different ways by which virus can enter to computer? I know removable devices like pen-drive, DVD, Internet cause virus to enter in the PC. But how do they enter? By which way? Can virus enter when we copy the content or simple open the removable device? Can virus enter by simply using the file by program ? Suppose I have pen-drive with virus. I know that. I want certain file of word to open. Now I will open the MS Word and open it by program of Word not directly double clicking on the file resting on removable drive. Can virus enter by this way?

    Well, Virus enter your computer by many ways. From the devices which you connect or the through internet. But all this happens because, as you insert a pen drive, you computer reads all the content in it. Suppose if your pen drive has the virus affected files, it reads that also. While the file are read, those virus just go and attack your system also. It is something like disease which get transferred to all if one get. Suppose you sit near a guy who has Cough and Cold, then its sure you will also get it soon. Like this only this Virus also. So if your system reads it, then it be transferred to it also. So only it has been advised to SCAN all the device before it is read and used.
    Thank you,

    There are following ways in which virus can attack your computer:

    1. Using virus infected USB or Pen drive
    2. Visiting websites related to movies, music etc.
    3. Downloading freewares - spywares also get downloaded in that process
    4. Opening virus infected attachments from mailbox
    5. Leaving your Bluetooth setting ON
    6. If your computer is on a network and any computer within that network gets infected with virus then your computer can also get infected.

    Always have an anti virus on your computer and timely upgrade it with new patches.

    Hello members!

    I have clearly asked in this question that by which way virus can enter the PC? by opening the file? just seeing the file in Pen-drive or exchanging the data?

    A virus is software or an application that is written by a software developer or what some would call a "cyber criminal" and tries to get on your computer through various methods in order to do various things, most of which will be discussed later. Viruses are created with the intent to replicate itself to other computers. Since a virus is software related and not hardware then a virus is very unlikely to be the cause of any hardware issues with your computer.
