TYPES OF COMPUTER VIRUSES AND MALWARE
A virus is generally understood as a type of malware that copies itself. Infects other
files (such as viruses in real life that infect biological cells for the purpose of
With the help of a virus, you can do a large number of different actions: access the
computer in the background, steal the password and make the computer freeze up
(the RAM is full and the CPU is loaded by various processes).
However, the main function of a malware virus is its ability to reproduce. When
activated, the programs on the computer become infected.
When you run the program on another computer, the virus infects the files here, for
example, a USB flash drive from an infected computer inserted into a healthy
computer will immediately transmit the virus to it.
The worm behaves like a virus. The only difference is in the distribution. When a
virus infects programs run by a person (if the programs are not used on an infected
computer, the virus will not penetrate there), the worm spreads through computer
networks on its own initiative.
For example, Blaster spread over a rapid period of time in Windows XP, as this
operating system was no different than reliable protection web services.
Thus, the worm used Internet access for the operating system.
After that, the malware moved to a newly infected machine to continue to reproduce
You will rarely see these worms since Windows today features very high-quality
protection: the firewall is used by default.
However, the worms do have the potential to spread by other means - for example,
via an electronic mailbox infecting a computer and sending copies of their own to
everyone on your contact list.
Worms and viruses can take many other dangerous actions when infecting a
computer. The main thing that gives malware its properties to a worm is the way it
spreads its own copies.
