Virus and what to do for virus protection
It is essential to know what you need to do for virus protection . A computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user.
And your need a virus protection that we call anivirus to save your computer. The term "virus" is also commonly used, albeit erroneously, to refer to many different types of malware and adware programs. The original virus may modify the copies, or the copies may modify themselves, as occurs in a metamorphic virus. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or the Internet, or by carrying it on a removable medium such as a floppy disk, CD, or USB drive. Meanwhile viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with computer worms and Trojan horses. A worm can spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a file that appears harmless. Worms and Trojans may cause harm to either a computer system's hosted data, functional performance, or networking throughput, when executed.
Virus Protection - Use antivirus
There are some tools and procedures that can tell whether your computer has a virus or if you need any virus protection . Here
are the actions to take:
Find out whether your computer has antivirus software for virus protection
Find out whether your antivirus software is up to date for recent virus protection .
If you already have antivirus software installed on your
computer, check out whether it’s
up to date and working properly.
Scan your computer for viruses: When you know that
your computer has antivirus software — and that it’s up to
date — you can use it to scan your computer for virus protection .
If you have an Internet connection, you might think that
you can take a shortcut and try one of those online virusscanning
tools — but don’t do that at this point! The risks
of connecting to the Internet without antivirus software
and a firewall are greater than the benefit you’d get from
knowing whether you have a virus — and you could end
up with a virus if you use the ’Net unprotected.Make sure you’re protected before you
venture out.
Remove the virus: If your virus-scanning tool finds a
virus on your computer, get
rid of the ugly thing. There are two basic outcomes:
Automatic removal: Chances are your virus scanning
tool will be able to fix your computer
by removing the virus. Newer virus tools will, in effect, tell you,
" I found a virus on your computer. Do you
want me to clean it up or not?"
You should just get rid of the virus
right away and deal with the consequences.
Manual removal — and more work: If, however,
your virus-scanning tool tells you that it cannot get
rid of the virus, a little more work is in order. For
instance, you may need to download a special virusremoval
tool from your antivirus software vendor;
such tools are sometimes built for specific, hardto-
remove viruses.
When you get rid of viruses, you’ve made a good start. (Done?
Who said anything about done?) Review the ways you use your
computer: Did something you do regularly get you into virus
trouble in the first place? By identifying the things you do that
expose you to threats like viruses, you can reduce your exposure
by doing some things differently. Preventive actions —
the cyber equivalent of washing your hands before handling
food — take a little time, but they can save a lot of misery later.

Virus Protection - Develope Good Habits
If you got a computer virus, human error was probably a
factor. Somebody probably wasn’t doing something right.
That, or you were extremely unlucky.
You may have opened an infected attachment by
mistake, or missed out on the latest antivirus update. Or your
friend who helped set up your computer may have skipped a
step or left the wrong default in place. However it happened,
you need to discover where the error came from.
You may be able to safeguard your computer by
changing some habits.
Up-to-date antivirus software is essentialfor virus protection . But
there are some other good defensive tools such as firewalls and
antispyware. In addition to these nice defensive tools, you may
still have some old habits to break and new habits to take up.
Now if you
read carefully and take my advice to heart, you’ll be much
safer in the long run.
Keeping antivirus software
up to date:
Antivirus software is of little value if it’s not kept up to date.
The best antivirus program
is next to useless if it’s not kept up to date.So update your antivirus regularly. This is required, unless you want to catch
more viruses in the future. Scan for viruses periodically Although rare, some
viruses can sneak onto a computer without being detected at the time of their
arrival. It’s a very good idea to scan your entire computer for viruses from
time to time — say, once a week.
Install security patches
Security patches are fixes that software companies make to
protect the computer programs. Some patches fix malfunctions that sometimes crop up
as a result of flaws in the product. If the flaws make your system vulnerable to
hackers, the software maker creates patches that fix those specific
vulnerabilities.
Working on good computer
hygiene
In so many ways, it’s a grubby Internet out there. You don’t want to interact
with it without protection. Fortunately, there’s a wealth of good habits you can
discover and adopt. They can be as effective (and simple) as washing your hands
after using the bathroom. Like backin up your data regularly, install only
prgrams known to be safe, securing your web browser, surfing the web safely,
sharing personal information carefully, avoiding spams etc
Blocking malicious network
traffic with a firewall
Like antivirus software, firewalls protect your computer. Their
function is to deflect the incoming bad things — viruses,
worms, and Trojan horses — that antivirus software can’t
always stop. Having a firewall can help — a lot.
Blocking spyware
If you’re like many of us, it isn’t hard to get into the mood to
give your computer a thorough cleaning Rather, I mean that it’s time to go
cloak-and-dagger and check for spyware on your computer.
Spyware can be a lot of things. In general, it’s software that
some Web sites and viruses install on your computer without
your knowledge so some person or company can track your
online movements, or even record your keystrokes with a key
logger.
Many people in the United States and Europe find it repulsive
to think that some total stranger knows about their Internet
surfing habits. So it is better to block spyware.
