Anti-Virus Programs If it's too good to be true, it's probably a virus! Warning Signs of a Virus When dealing with a virus, it is

Now some viruses will be able to outsmart your anti-virus. If you have one of these monster infections, you will have to bring your computer to a professional for removal. Removing the Virus By: Kyle Lavorato Trojan Horse Spyware Definition Malicious Software Malware for Short Malware refers to software programs designed to cause damage or perform unwanted actions to a computer system. "Mal"=Bad So Basically Its Badware... There is approximately one million viruses hidden in the World Wide Web, making it a difficult task to stay safe.

Unfornatuly, the average computer is at high risk of malware infections, but it is possible to stay safe.

We can take many precautions to keep our computers malware free. But Are We Safe From These Threats? There are many Different types of Malware, and each type effects your computer differently. So What "Harm" Does
Malware Cause? As the name implies, spyware is malicious software that spies on you.

You may think, "so what if someone knows what I am doing on my computer?"

Well, when you go buy those concert tickets online, the spyware captures your credit card number and sends it to the criminals running the program.

Perhaps you send a private message to a friend. The spyware captures that too. $pyware Secretly Installs, so you don't know its there. $pyware can cost you lots of money! Just like in ancient Mythology, Trojan Horses are malware
disguised as normal programs.

They can be disguised as anything really, a computer game, word
processor, or even an anti-virus program.

When active, Trojan Horses can cause large amounts of
damage, such as corrupting your data.

Fortunately, Trojan Horses are only activated when run and
can easily be detected by an anti-virus beforehand. Trojan Horses "Programs In Disguise" Adware is simply free software that is supported by advertisements. This will usually be in the form of free toolbars or helpful programs.

Adware is not normally malicious, but is very annoying. As long as it is active, it will continuously open ads in pop-up windows or display them over the content you are viewing. (eg. the ads on a YouTube video)

As I previousaly mentioned, Adware is not normally malicious, but it is possible. Sometimes, it may secreatly be spyware, which can be quite dangerous. Adware Everybody Hates Those Annoying Ads! Malevolent Macros Macros Malicious Macros A macro is a small program or script, that will automatically complete a simple task when triggered.

They are commonly used in Microsoft Word/Excel to perform tasks such as entering an address when a key combination is pressed. Although macros are very helpful, some are very hurtful as well. Malicious Macros will damage your computer, just like other malware.

They will usually found on downloaded MS Word/Excel documents.

Once activated, they can copy themselves to your other documents, to spread to
other users.

To prevent this, you can disable the macro feature in the programs. The effects are only triggered once the macro is run. Just like a real earthworm, worms tunnel through your computer's hard drive. Once on your computer, worms will contuine to rapidly replicate itself.

The worm itself does not harm your computer, but it is still dangerous. Worms will contuine to multiply until all availabe memory on your computer is used. This will make your computer incredibly slow.

The worm itself is an invisible file and will most likely be undetected until large chunks of memory are filled. Worms are espically dangerous because of the fact that they need no user interaction. They will secretly infect your computer and other computers.
Worm A good anti-virus program will greatly decrease the chances of your computer becoming infected.

Anti-virus software has many uses such as:
Preventing viruses from being downloaded
Blocking suspected malicious content
Preventing viruses from being spread
Keeping your computer protected in real time
Quarantining and removing malicious software from your computer Simple Ways to Stay Safe Update your Anti-Virus software - New malware is created daily, and will slip past old anti-virus definitions undetected.

Scan all e-mail attachments - Malware can secretly attach itself to an e-mail, so an infected friend can pass it onto you.

Do not download programs from the Internet - A file with the .exe extension, downloaded from the Internet, may not be that game it says it is. Only download from trustworthy sources and make sure to always scan the files. Is your computer running very slowly?
Is your modem/hard drive running rapidly?
Has your anti-virus given a warning message?
Are you getting strange pop-ups for simple tasks?
Are your file's sizes changing whitout you accessing them?
Is your computer just generally acting strange?

If you answered yes to any of these questions, you may
have a virus on your computer.
Inportant Info One inportant thing to remember
with viruses, is to always unplug
your Internet if you suspect you
have a virus. This will prevent
your computer from infecting
others. It will also prevent
your computer from transmitting
its data to the virus' programmer. Please ask if you have any questions. Thanks For Your Attention Bibliography http://us.norton.com/products/library/article.jsp?aid=virus_tips http://www.bleepingcomputer.com/tutorials/keep-your-computer-safe-online/ http://www.techterms.com/
