What
is it a computer virus?
Definition: A bug may be a malicious software program
loaded onto a user’s computer without the user’s knowledge and performs
malicious actions. In more technical terms, a computer virus is a type of
malicious code or program written to alter the way a computer operates and is
designed to spread from one computer to another. A virus operates by inserting
or attaching itself to a legitimate program or document that supports macros in
order to execute its code. In the process, a virus has the potential to cause
unexpected or damaging effects, such as harming the system software by
corrupting or destroying data.
Description: The term computer virus was first formally
defined in 1983. Computer viruses never occur naturally. they're always induced
by people. Once created and released, however, their diffusion isn't directly
under human control. After entering a computer, an epidemic attaches itself to
a different program in such how that execution of the host program triggers the
action of the virus simultaneously. It can self-replicate, inserting itself
onto other programs or files, infecting them within the process. Not all
computer viruses are destructive though. However, most of them perform actions
that are malicious in nature, like destroying data. Some viruses wreak havoc as
soon as their code is executed, while others lie dormant until a specific event
(as programmed) gets initiated, which causes their code to run within the
computer. Viruses spread when the software or documents they get attached to
are transferred from one computer to a different employing a network, a disk,
file sharing methods, or through infected e-mail attachments. Some viruses use
different stealth strategies to avoid their detection from anti-virus software.
for instance, some can infect files without increasing their sizes, while
others attempt to evade detection by killing the tasks related to the antivirus
software before they will be detected. Some old viruses confirm that the
"last modified" date of a number file stays an equivalent once they
infect the file.
How
does a computer virus attack?
Once
a virus has gone through a program or file, the virus will lie until
circumstances make the computer or device execute its code. In order for a
virus to infect your computer, you have to run the infected program by yourself, which triggers virus code to be executed.
This
means that a virus can remain lurking in quietness on your computer, without
showing major signs. However, once the virus infects your computer, the virus
can infect other devices on the same network. Stealing your secret data
including passwords, logging keystrokes, corrupting files, spamming all your
emails, and even taking over your machine are just some of the annoying things
a virus can do.
While
some viruses can just as playing in its effect, others can have damaging
effects. This includes deleting data or causing permanent damage to your hard disk
and other PC components. Worse yet, some viruses are designed with financial
gains as a target.
