Safety information: Before you start removing or installing a display make absolutely sure that the plug is pulled and the battery is removed from the computer/laptop. All power supply must be removed. CAUTION! Computer/Laptop components might contain HIGH VOLTAGE!!
A computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user. 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 Virus can be introduced to a computer through many different ways. They can be attached to an email, hidden in a CD-ROM or USB drive, installed unknowingly when installing supposedly legitimate software, through a network from another infected computer, and through unsafe surfing with an un patched computer.
Anti-virus software and other preventive measures:
Many users install anti-virus software that can detect and eliminate known viruses after the computer downloads or runs the executable. There are two common methods that an anti-virus software application uses to detect viruses. The first, and by far the most common method of virus detection is using a list of virus signature definitions. This works by examining the content of the computer's memory (its RAM, and boot sectors) and the files stored on fixed or removable drives (hard drives, floppy drives), and comparing those files against a database
of known virus "signatures". The disadvantage of this detection method
is that users are only protected from viruses that pre-date their last
virus definition update. The second method is to use a heuristic
algorithm to find viruses based on common behaviors. This method has
the ability to detect viruses that anti-virus security firms have yet
to create a signature for. Recovery methods:
Once a computer has been compromised by a virus, it is usually
unsafe to continue using the same computer without completely
reinstalling the operating system. However, there are a number of
recovery options that exist after a computer has a virus. These actions
depend on severity of the type of virus.
Virus removal:
One possibility on Windows Me, Windows XP and Windows Vista is a tool known as System Restore,
which restores the registry and critical system files to a previous
checkpoint. Often a virus will cause a system to hang, and a subsequent
hard reboot will render a system restore point from the same day
corrupt. Restore points from previous days should work provided the
virus is not designed to corrupt the restore files or also exists in
previous restore points.
