How virus can enter in a computer?
A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the owner. The term "virus" is also commonly but erroneously used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.[1][2] In order to replicate itself, a virus must be permitted to execute code and write to memory. For this reason, many viruses attach themselves to executable files that may be part of legitimate programs. If a user attempts to launch an infected program, the virus' code may be executed simultaneously. Viruses can be divided into two types based on their behavior when they are executed. Nonresident viruses immediately search for other hosts that can be infected, infect those targets, and finally transfer control to the application program they infected. Resident viruses do not search for hosts when they are started. Instead, a resident virus loads itself into memory on execution and transfers control to the host program. The virus stays active in the background and infects new hosts when those files are accessed by other programs or the operating system itself. http://en.wikipedia.org/wiki/Computer_virus#Infection_strategies

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.

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,

Here are opinions and answers from contributors:
- I ran Grisoft AVG(Free) and it detected the crypter.E virus but could not remove it. I checked the test detail which listed the associated file"mousedrv.exe" located in C:/Windows/System32. I could not delete it because it was running, so I opened Task Mgr,clicked on processes tab and found the file. I ended it with Task Mgr "end" command then went to the System32 folder and was able to delete mousedrv.exe. However when I restarted my computer,a message appeared saying mousedrv could not be run from the registry. Using regedit, I found several run entries in the registry and deleted them. Restarted my computer again with no messages and ran Grisoft AVG again which did not detect a virus.
- I went on avg free edition and it didn't locate it but adaware pro did seek it out and then deleted it but then when I rebooted the PC it came back so I went on hard disk and then found it under the name of program 4,and then it wouldn't delete so I run a spybot on the actual program and it found 419 viruses on the program and then it enabled all the viruses open so I had to boot the PC up in safe mode then the files were able to be deleted, so boot up in safe mode and then delete the files.

How do you reboot Windows in Safe Mode?
There are two ways you can do this.
Assuming you can get into your computer, you can set it up to automatically reboot in Safe.
1. Press and hold the Windows key + R to execute "Run"
2. Type "MSCONFIG" without quotes, press enter
3. Open the second tab: "Boot"
4. Find the "Boot Options" box (just under the "Advanced" button")
5. Tick the "Safe boot" checkbox
6. Click "Apply", then "OK"
7. Restart Windows 7 as you normally would.
This will automatically start Windows 7 in Safe Mode.
REMEMBER TO GO THROUGH THE ABOVE PROCESS TO
REMOVE THE SAFE BOOT OPTION, ONCE YOU'RE DONE,
OR YOU WILL CONTINUE TO START UP IN SAFE MODE!
The second method is infinitely easier, but it requires
a little bit of precision timing, to pull it it off.
1. Start your computer
2. After the Manufacturer's screen splash, press "F8"
3. Enure you do this before the "Starting Windows" splash comes up.
4. This will bring up the OS's "Boot Options"
5. Select "Safe Mode"
6. If you need Internet while in safe, select "Safe Mode with Networking".
Unlike the first method, this will launch the OS in Safe Mode only when
you press F8 to access boot options; when you restart Windows 7, it
will launch normally.
You may need a couple of tries to get your timing right, between the
manufacturer's screen, and the "Starting Windows" splash.
