Virus :
In computers, a virus is a program or programming code that replicates by being copied or initiating its copying to another program, computer boot sector or document. Viruses can be transmitted as attachments to an e-mail note or in a downloaded file, or be present on a diskette or CD. The immediate source of the e-mail note, downloaded file, or diskette you’ve received is usually unaware that it contains a virus. Some viruses wreak their effect as soon as their code is executed; other viruses lie dormant until circumstances cause their code to be executed by the computer. Some viruses are benign or playful in intent and effect (“Happy Birthday, Ludwig!”) and some can be quite harmful, erasing data or causing your hard disk to require reformatting.
Virus Protection
Virus protection software is designed to prevent
viruses,
worms and
Trojan horses from getting onto a computer as well as remove any malicious software code that has already infected a computer.
Most virus protection utilities now bundle anti-
spyware and anti-
malwarecapabilities to go along with anti-virus protection. Internet security suites go a step further by including additional capabilities like
anti-spam, anti-
phishing, firewall, file protection and PC optimization.

In The Last,
Facebook virus or account hacked? Here’s how to fix it.
You’ve just discovered your Facebook account has been posting all kinds of
weird,
pornographic, or
generally inappropriate content to your Wall and/or News Feed. Your friends are annoyed with all the questionable posts and requests coming from you.
Did you forget to log out of Facebook at your friend’s house, did you accidentally click on something you shouldn’t have, or has your account been hacked?
I can’t answer these questions without actually seeing what’s happening on your profile, but I can offer some advice. Here are three things you should try in order to clean up your Facebook account.
Change your Facebook password
It’s possible your Facebook woes are coming from the result of a phishing scam. Someone may have created a fake website that looks like Facebook or another online service you visit and tricked you into logging in. Their goal was to steal your password and other account credentials, and they may have succeeded.
If changing your password fixes your Facebook problems, you should change your password for all your other services too, especially if you use the same password for them as you previously used on Facebook. If this doesn’t fix the problem, try the next step.
Remove unwanted Facebook apps
It’s possible your Facebook woes are coming from a rogue app that you accidentally installed or were tricked into installing. Every Facebook app has certain permissions to your account. Some of these permissions you can modify, while others you cannot.
Your best bet is to remove all the Facebook apps you find suspicious. If you don’t know how to do so, you can refer to the following guide:
How to clean up your Facebook apps.
If cleaning out your apps fixes your Facebook problems, tell your friends they should do the same (chances are the app asked your friends to install it as well). If this doesn’t fix the problem, try the next step.
Get some security software and run a virus scan
It’s possible your Facebook woes are coming from some sort of malware, be it a keylogger, a trojan, or some other type of virus. Even if you think your computer is clean, it can’t hurt to check.
The aforementioned security programs are for Windows. If you have a Mac, try using the antivirus from
Sophos.
After running the virus scan, clean out whatever the program detects. If you’re not sure about what it found, ask a friend who might.
Facebook today released the Guide to Facebook Security, a free handbook aiming to educate parents, teachers, and young adults on how to keep their Facebook accounts safe. You can download it now from the
Facebook Safety Center.
The 20-page guide was written by former Symantec internet safety expert Linda McCarthy, Purdue University security researcher Keith Watson, and teacher/editor Denise Weldon-Siviy. It includes tips on how to:
- Protect your Facebook account
- Avoid scammers
- Use advanced security settings
- Recover a hacked Facebook account
- Stop imposters
Facebook says the guide answers typical questions parents, educators, and teens have about making Facebook more secure. More specifically, the social network promises that it answers these four questions:
- What can you do to protect your Facebook account when accessing it in public?
- What should you do if someone hijacks your Facebook account?
- How you can use Facebook’s advanced security settings to protect yourself?
- How can you help in keeping you and your friends safe and secure while online?
Furthermore, the document explains how to protect your account, avoid scammers, and configure advanced security settings. If tells you how to setup one-time passwords, secure browsing, and track your account activity, if you don’t do this already.
Most interestingly, it explains why scammers and thieves want your account. Even if you already consider yourself a Facebook expert, this one is worth a read, or at least a skim.
