It's impossible to answer this question. Over 50 websites are being created every second. 20% of websites have viruses.

Their are many parts of a computer that viruses infect. Most viruses infect a certain file or program so that whenever that file is run, the virus is also executed. Some viruses called Master Boot Record viruses infect the Master Boot Record of your computer. The Master Boot Record is the partition of your computer first executed when you boot up your computer. When you turn on your computer, it runs all the programs inside the Master Boot Record partition and then passes control to other child processes. Viruses in this class infect the Master Boot Record so that whenever your turn on your computer, the viruses runs at startup too. These viruses are very tricky to find as they hide in a very deep part of your Operating System and manually deleting them could damage your computer.
Just like a computer. Downloading bad applications, going to the wrong sites, and many more! It is just like a computer.
Bacteria,fungi,or parasitic worms invade the human body.
The most common side effect of a computer virus is a slow down. Apps will take longer to start up or webpages will not load. Viruses take up vital CPU cycles. Unfortunately, it gets worse. Many viruses will use you computer to infect other computers or steal your personal information.
Here is a list of 10 different computer viruses. The storm virus, Sasser virus, Nimda virus, Melissa virus, Code Red 1 and 2 virus, Morris virus, ILOVEYOU virus, Brain computer virus, Conflicker, and Elk cloner are 10 different computer viruses.
Good question.Viruses can enter computers in many ways. Once a virus has entered a system, it will generally hide until it is unknowingly run by the user. A virus will not act until it has been run or some pre-established condition has been met, such as a specific date. The effects of a virus may not be noticed for some time after it has infected a computer.Viruses can infect several components of a computer's operating and file system including:System Sectors/Boot Records - Viruses can infect the parts of the system that are used to run programs and perform functions such as start up and shut down.Files - Viruses can infect program files. These viruses stick to program files such as .com, .exe, .sys, etc. Some viruses hide in the memory of the computer at first, while others simply attack a specific software program, such as Microsoft Word.Companion Files - Viruses can create companion files that are a special type of file that adds files that run on the hard disk.Macros - Viruses can infect macro or data files.Disk Clusters - Viruses can infect files through the disk directory.Batch Files - Viruses can use batch files to infect a computer.Source Code - Viruses can be in additional code that is added to actual program source code.Visual Basic Worms - These worms use the Visual Basic programming language to control a computer and perform tasks.
Similar to biological viruses, they have the capacity to reproduce. Also, they infect files - becoming part of the file. This is similar to biological viruses, invading the cell.Note that in popular usage, the term "viruses" is used for many types of malware (malicious programs); but a computer virus is actually only a very specific type of malware.
Computer viruses are currently unable to spread to humans.
All of them.
Viruses are malicious software (malware) in which their sole purpose is to replicate and infect non-infected computers. Their are many mediums to which a virus can infect a computer, most commonly through the internet and email attachments. When viruses infect a computer, it attaches itself to a "host" file (hence the name virus because it acts like a real world virus). Next, it injects its code into the host file so that whenever that infected file is run, the virus executes first and then the actual file starts. The "payload" is the official term to the effects a computer virus has on a PC.
