There are many different types of computer viruses. The Melissa virus is an example of a macro virus, while the Aircop virus is an example of a boot sector virus. Anna Kournikova is an example of a worm, as is ILOVEYOU.

A computer virus is a software program that can copy itself and infect a computer without the permission or knowledge of the owner and is spread from one computer to another. Personal computers are connected to the internet and to local area networks, that facilitates the spread of malicious program code. also taking advantage of network services such as the World Wide Web, e-mail, Instant Messaging, and file sharing systems to spread.

In computing terminology, a macro virus is a virus that is written in a macro language: that is to say, a language built into a software application such as a word processor. Since some applications (notably, but not exclusively, the parts of Microsoft Office) allow macro programs to be embedded in documents, so that the programs may be run automatically when the document is opened, this provides a distinct mechanism by which viruses can be spread. This is why it may be dangerous to open unexpected attachments in e-mails. Modern antivirus software detects macro viruses as well as other types.

The naming of the computer virus has sort of the same roots as the computer bug. When the first viruses were discovered, people named it based on the main aspects of the object. The viruses focused on dumb cloning/reproducing, exactly like organic viruses, and there you go, the computer virus is born.

Bernd Fix was possibly the first person to remove a virus publicly from a computer.

But the first 'Antivirus'application came on the Atari ST which was released by the Atari corporation in 1985.The antivirus on the computer was called 'G Data' by G data software inc.

Yes it most certainly is possible to get anti-virus software on your smartphone. Many manufacturers are designing the software for you to download directly to your mobile smartphone.

When a hard disk is said to have "crashed" it means that the read/write head has come in contact with the magnetic medium. The read/write head is SUPPOSED to "fly" above the surface, never actually touching down.

The disk turns at such a high speed that if the head touches down it destroys the surface resulting in what is affectionately called a "head crash" or a "disk crash".

A computer virus cannot cause that kind of hardware failure.

Viruses generally range from 20 nanometres to 300 nm in diameter although the largest can be as much as 500 nm. Their lengths range from 700 to 1000 nm.

Many people have an antivirus applications installed but they do not configure them correctly. Just installing the application does not mean that the application is working properly to stop the threat or infection. You must update your antivirus software regularly. Below is a tips to check either your antivirus software are working or not.

- Open your Notepad

- Copy the code exactly in the notepad : X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

- Now Save it with the name fakevirus.exe in any of your folder/drives.

- If this file got deleted immediately, then it means that your antivirus is working properly and updated !!

- If this doesn't happens and you see the saved file in that folder do right click the file and select scan with your installed antivirus and if the scan shows the file then it means your antivirus is working properly but not updated with a new version, as best antivirus softwares detect any virus (at the same second when you save the same in your system)without your effort of going to specified folder and scanning the folder.

- If it doesn't shows any kind of threats then you need to change your antivirus software immediately with some good one with the new version.

Such email attachments can be dangerous as they may contain worms and trojans that can immediately infect computers, once opened by the unsuspecting user.

There are a lot of things that one can do to protect his/her computer from the risks coming from email attachments:

- Configuring the email client used, to block opening/saving of email attachments that may have risk potential. As an example, Outlook has an option to block email attachments that are potentially dangerous.

- Use an antivirus that also has the ability to scan incoming/outgoing email. Norton Antivirus is an example of such product. The antivirus works by scanning incoming/outgoing emails, and in most cases they are able to clean up the message by removing dangerous/infected attachments, and preserving harmless content. It is very important to keep your antivirus updated on a daily basis, so you are protected from the latest worms and dangerous executables that may be sent through email attachments.

- Learn about email attachment risks. Keep informed about the latest virus threats that come via email, and how they disguise themselves in order to be opened by the unsuspecting user.

- Disable hidden file name extensions on your Windows-based computer. Some attachments may come as exacutables with a hidden extension, like .shs or .lnk for example. A virus may reach your computer as an email attachment with two extensions, for example FILENAME.TXT.shs ; due to the fact that .shs files have hidden extension on Windows computers, the user may try to open the FILENAME.TXT file which may seem harmless, but in fact he ends up executing the .shs binary file and infecting his computer in this fashion.

- Pay attention to filenames. There are lots of cases when hidden extensions are used, just like described above. Also, in some cases there are a lot of spaces inserted inside the filename, so the true extension of the file may scroll that much to the right, that we can't see it inside email client.

- Do not open any kind of email attachments that appear suspicious. Do not open any kind of executable files that are being sent to you. Some people may send you funny video files or similar things; they may even be your friends, unsuspecting that what they are sending actually contains a virus. Do not send such email attachments to your friends as well.

- Do not open email attachments from people that you do not know or you do not trust.

- Be aware that there are some files that come as email attachments in the format of zip files or other archives, in orde to trick antivirus scanners from detecting executable content. If you receive a zip file from someone you do not know, you should assume it must be dangerous.

- Be aware that Office documents like Excel spreadsheets or Word documents can be dangerous as well. Some people are actually sending emails with Office documents as attachments, even unaware that the documents they are creating and sending to you, are infected by a macro virus, which is a virus written for Office documents, since Office documents can contain hidden programs. To protect from such problems, disable macros in your Office programs.

Hopefully, these advices will prove useful to you, in protecting your computer from risks coming from email attachments, in the future.

I have done this once before, but I only know how to do it on Vista.

Go to start and search for "rstrui" choose the one that pops up. Now chose another restore time when you didn't have security shield and click next. Now select a time and click next again. Now click complete and your computer will restore your old settings where you didn't have security shield. It might take some minutes.

Not necessarily, as long as you watch videos that have the small "play" triangle looking icon on the video you are fine. It will play the video through yahoo but if you click on a video that doesn't have one that's were your virus will come from.

Yes, a Mac can crash, in rare circumstances. PCs crash more than Macs so more people are getting Macs. However, the terminology is incorrect. Macs actually hang, and Windows PCs crash.

Oooh, I got a nasty virus that did that. It went by many names, but the form it appeared in to me was "Win7 Home Security 2012". It also goes by names such as "WinXP Home Security 2012", "WinVista Home Security 2012", et cetera, depending upon your operating system. I'm sure it's not the only virus that does this, but the nasty booger invaded my real security program, and told me that my security was infected, and to get rid of it.

So, er, yeah. I do hope this ramble actually answered your question.
