What is a resident virus?

Resident virus is a computer virus that is inserted into a computer memory, activating the operating system at any time to perform a specific function to infect files on your computer. This method of viral infection is in contrast to the non -resident virus who actively seeks files. Resident viruses can be quite malignant because they can expand through the system so thoroughly that they even connect to antiviral programs and infect things looking for signs of viral infection.

There are many ways to design a resident virus. Virus designers must think about the level of infection when developing the virus. Some are fast infections and move as quickly as possible through the system to cause the greatest damage. Others move slower. Viruses that move quickly reveal because they cause problems with the performance of the operating system, but it may not be a problem in the eye of the creator, because the damage is already knowown. Viruses that move slowly can be better placed so that inflicked other computers or remained hidden for a longer period of time.

Removing a resident virus that has been built into the computer memory can be a challenge. The virus can be designed to withstand the activities of conventional antivirus software or, as mentioned above, to use the software. A specialized virus removal tool may be required to extract the virus from memory. In some cases, the information technology professional services may be required to complete the computer.

When a resident virus is identified by an antivirus company or a designer of operating systems, repair is often released. It can be an antivirus program update that allows the program to remove the virus, or it may take the form of a virus removal tool that a computer user can run to get a resident virus from the memorial.

searching tools for fighting with VIRem can be challenging. Ruthless people can release programs that claim to fix viruses, but in fact load more viruses or other malicious programs such as spyware to your computer. Computer users should search for reputable sources of advice and software for removal of viruses such as official websites for operating system manufacturers or antivirus programs.
