What is Computer Virus?
A computer virus is one of thousands of programs
that can destroy files and data of our computer systems and perform a variety
of functions ranging from annoying (e.g., popping up messages as a joke) to
dangerous (e.g., deleting files or destroying your hard disk).
How Do Computer Viruses Spread?
Computer viruses usually spread in one
of three ways:
ü By
removable media
ü Downloads
the files from Internet
ü From
e-mail attachments
In fact, it’s nearly impossible for a
virus to be transmitted by plain-text e-mail. Most viruses can only spread via
attachments — either rich-text e-mail or attached applications.
Internet gets a bad rap as a source of viruses; it
has a lot of fake links when someone clicking on fake links then a setup file
download and when install it. Virus can enter into your computer.
If once a virus enters into our computer then it start
destroys our data without our knowledge and it replicate itself one drive to
another.
So we must need to be aware to protect our digital
data. Otherwise any time we lost our all important information which stored
into our computer.
Always keep an Antivirus in our computer system to
protect our data. Before downloading any file form internet must need to scan
it by an antivirus and if any virus detect any time then immediately delete
that particular file from our computer.
Not only before downloading form internet if any friend send to you any file without acknowledgement then first confirm its secure or virus free then download.
