There
are so many systems facing a problem call “Virus”
What
is this?
Simple
Definition
The virus is a program/code designed
to reduce the PC/Laptop performance. Here I would like to mention all the
viruses are not cause any damages to the PC. All the virus programs are mostly
cause the PC data’s.
How
the Viruses attack data’s?
There are so many methods the viruses
use to attack data’s, but commonly it uses 3 different types of performances it
uses to attack those are,
·
Duplicate
it itself
·
Attack
to other program or instruction
·
Perform
unintended actions
These are the performance the viruses
commonly use to attack data’s from the PC/Laptops.
Note: The viruses are dangerous it can
delete important file/data from our PC/Laptop
Main
Types of Virus
1.
Boot

How
the Virus transmitted from one system to another system?
To transmit the virus there are some
common factors are include those are,
1.
Download
files/data from internet
2.
Use
of external devices
Download
files/data from internet
When we borrow the internet we will use
download option to download some file or data that we want. Here if the virus
files attached with the downloading file the virus simply spread on our
machines when we open the downloaded file.
Use
of external devices
Nowadays we knew so many input devices
are available to store files and data’s. So when we transfer a file from
another PC/Laptop, here we have to consider if the file transferring PC or
Laptop has viruses differently the receiver PC will be attack by the virus.
How
to identify the virus attacked PC?
There are some of the basic symptoms
that a PC will show up when effected with the virus, those are,
·
Windows Start up be slow
·
Programs
take long times to load than normal
·
Computer
hard drive constantly runs out of free space
·
The
hard drive runs when we are not using it
·
New
files keep appearing on the system and we don’t know where they came from
·
Some
different screen performance will appear on the screen
·
Files
have strange names we don’t recognized
·
Program
size keep changing
·
Programs
act erratically
These are basic Symptoms we can
identify when our PC effected by the virus.
How
to Protect our PC from Virus?
Here I would like to mention 2 methods
its 100% enough to protect our PC from virus.
- Anti-Virus Guard software Protection
- Switch on the Fire Wall system on our PC
Note: I kindly request you the protection
method will 100% enough when we use genuine open source on our system
Anti-virus
Software
This software contains anti-virus
scanners, which look for viruses. There are two types of virus scanners.
i.
On-access
scanners:
Automatically check the hard disk and
diskette each time the system starts up.
ii.
On-demand
scanners:
Executes only on users demand and can
be scheduled to run at various time.
Most commercial anti-virus software
provides both types of scanners. It will take some time for an anti-virus
software designer to get to know about new types of virus and to write software
to detect it. Therefore anti-virus software gets out of date very often.
Note: Use Microsoft Essential Security
system to protect your file and data from virus. The MES is the best protection
system, that I will suggest you.
Firewall system
A computer generally has many ports
(think of them as doorways), which allow external programs to access the
computer. Hackers use programs to automatically detect vulnerabilities in the
computer and gain access to the computer by using this weak access points. Firewall
protection secures these ports so that no malicious programs can sneak into
your machine.
So these are the 100% protection idea
to protect your PC from virus. Hope the post will help you to get the idea
about virus.
Thank you by Admin
