What are ways a computer can become infected on the internet?

There are a few ways evil can find its way onto your computer. The most common way is opening attachments that supposedly came from your friend. Spyware and viruses can sometimes send messages with copies of the virus from your friend to everyone in their address book, pretending to be your friend. Rule of thumb: never open any attachment from any email that you didn't expect. Another way your computer can get infected is if you download a rogue file on the internet. Always check to see if what you're downloading comes from a reliable source. If in doubt, have an anti-virus program scan the file before you run it. The most malicious virus is a Trojan Horse program, a term used to describe a virus that pretends it does one thing, while it really messes up your computer. Be very cautious what you download and always scan what you download. Some websites phish other websites (pretend to be the true website), but phishing checkers are available on the internet. If you download a file that has an extension (such as .jpg or .doc) that you are not familiar with, immediately delete the file and double check the website to make sure that you're downloading something safe. Some programs freely admit to being spyware to prevent lawsuits (usually on paragraph 56 of the 57-paragraph license agreement). Bottom line: be sure of what you download and always scan it before you run it. Next, never start your computer with a floppy disk in the floppy disk drive. Not even that "game" (wink-wink) Bob slipped you last week. Your computer is most vulnerable as it starts up. As part of your start-up routine, eject any and all floppy disks. Finally, some evildoers can get into your network, destroy and vandalize, slip in some viruses, and run away unnoticed. This is only true if your router has any wireless capability. To counteract this, watch your windows for any masked men crouching by your house with a laptop in hand. Better yet, be sure to enable security for your router (usually go with WPA unless some hardware is incompatible) and create a strong, secure password. And don't get paranoid. 90% of what you download on the internet is safe, especially if the website you're using is either secure (look at the URL for https://) or is checked by third-party software (you'll usually see an ad somewhere on the page that says "Virus-Buster Protected!" or some other stupid slogan. Breathe a sigh of relief when you do.). Hope this answer helps!

How you can minimise the risk of computer viruses?

Email Attachments

Firstly, be very careful when opening email attachments.

Historically, hackers sent their malware via email for best effect. As soon as someone opened an attached file they would be infected.

Whilst this attack vector is less common these days it is still used and so I would recommend that you never open files from unknown senders.Additionally, you also need to be wary even if you do know the sender - if your friend's machine has been compromised they they could be unwittingly passing a virus onto you.

Be Careful What You Download

Everybody downloads files from time to time.

Most of the time I would imagine this is quite legal and genuine but some people do download music and films that they haven't paid for.

Malware authors love these people - they infect such files before uploading them to peer-to-peer sites, knowning hundreds of thousands of people will be too excited about getting something for nothing to worry about the risks.

Don't do it!

Backup Your Files

Even the best of us pick up viruses.

Or mess our computers up so badly that we have to reformat and start again.

If that happened to you would you have lost years of work, or cherised films and photos?

Don't let it happen - backup regularly.

Protect Yourself With An Antivirus Program

Bit of a no-brainer this - if you don't want viruses on your computer then install an antivirus program!

If you buy a good quality antivirus program from a reputable vendor then you will set it up once, ensure it updates itself regularly and then forget about it, safe in the knowledge that it is protecting you from a wide range of threats.

I would recommend that you check out F-Secure Antivirus 2010, the program I have running on my own computer right now.

Do you hibernate the computer does harm?

Hibernation is very good for your computer. When you leave your computer for a long period of time, like at night, then put it in Hibernate. It will close all your programs like they are suppose to close and when you start again you will be right where you left off. The worst thing you can do to a computer is just shut it down with the button which is called a cold boot. Files get damaged since they could not be saved correctly,

If you are receiving emails with attachments that will not open do you have a virus?

This is more likely a case of someone else having a virus and your email address is on their computer. There have been several viruses that send themselves to all the email addresses in the infected computer's address book. Some of the latest ones do not show the originator as the "from" address, but randomly pick another address found on the infected computer. A good virus detection program like McAfee or Norton will catch these emails and quarantine or remove them.
