A computer virus is a self replicating virus that tends to damage data on a computer. A virus behaves in much the same way as an actual virus, except that it cannot reproduce itself. Instead, it copies itself into another program or file. The original virus can be dangerous because it can destroy or damage files permanently or leave a bypass trail that allows hackers to break into your system and gain access to your personal information.


Viruses behave similarly to the way a cold virus does in that they replicate themselves by borrowing genetic material from their host cell and then replicate again. A virus is like a virus that is passed on from one generation to the next by contact. Viruses can infect many types of living things, such as plants, animals, and bacteria. Viruses have a basic structure, so that they are very easy to identify, and they possess a very basic set of instructions that allow them to duplicate. This basic structure makes them extremely difficult to stop due to their copying ability.

Because viruses are extremely damaging to a computer, they are typically found on infected computers when a virus has managed to spread from host to host, or when the user opens an attachment or file that is attached to an email that was sent from a malicious or infectious source. The attachment may contain a virus, or may not, but the virus can often spread from host to host. Once the infected file or attachment is downloaded, it is then potentially become infected with the viral replication process.

When a file becomes infected with a virus, it infects a part of the computer’s memory called the’registry’. The registry is a database of all of a computer’s files and settings which keep everything running correctly and give the PC all the necessary instructions for it to run as smoothly as possible. Because viruses have the ability to replicate themselves within the registry and change important settings, they often cause a great deal of damage to the system. They remove vital files and settings which make the PC unable to function properly. Not only does the PC become unstable, it also becomes damaged, making it extremely difficult to fix in any way.

Viruses have been found to be able to spread rapidly when a host has a bad download or has a security vulnerability. Because the virus is able to replicate within the registry, it is often the case that if a virus has managed to spread to a PC, it will have caused a lot of damage. A virus can cause your PC to crash, for example, or may prevent you from loading certain files or software. It may also be able to steal your personal details and bank passwords by embedding them within the documents or files you download. If the infected file contains a security vulnerability, this means that anyone who has access to the internet can gain access to your confidential data and personal details.

In order to protect your PC against complex viruses like the one mentioned above, you should download a free anti virus tool from the internet. Anti-virus programs are designed to scan through your PC and remove all known viruses. They work by hunting through every part of your computer, looking to identify any unfamiliar files, settings and commands which may have been embedded within it. They then search through each file and every setting on your computer to remove any malicious elements that are attempting to infect it. By using a good program, you’ll have much more chance of successfully protecting your PC from complex viruses such as the one described above.
