Ways to Clean the Device From Viruses | Total Security Software
A virus is a malicious program that is loaded on the user's computer without his knowledge, and
it consists of a set of instructions that stick to various computer programs, so that the programs
implement the instructions of the virus invisibly, despite carrying out its usual functions, and the
virus begins its work when it reaches the device's memory, and instructs the program The host
has to copy the virus code to other programs and infect them, and the virus may be transmitted to
other devices using magnetic disks and various storage media that connect to the infected
computer, so it is important to know ways to clean the device from viruses.
Types of computer viruses
Before talking about ways to clean the device from viruses, one should know the types of viruses
that infect the computer. Computer viruses have been classified according to the method of
infection and behavior into the following main types:
Boot Sector Virus: infects the device's hard disk, where the master boot records MBR are
stored, and when the device is turned on, the virus attacks the memory and begins the process of
controlling the device.
File wipe virus: Designed to delete important files, which are part of the operating system.
Mass mail virus: This virus searches for e-mail addresses stored in the address book and begins
to reproduce by sending itself to these addresses.
Macro virus: These viruses are written using different programming languages, and the macro is
a way to simplify the tasks that the computer frequently performs, and macros are stored as part
of documents and data files, and they are transmitted to other devices when this data is
transferred to them.
Mutated viruses: Each time these viruses infect a different system, they have the ability to
change their appearance or code, and thus are difficult to detect by anti-virus programs. Armored
viruses: These viruses are designed to be difficult to d
