worm or virus? and how to deal with it?

May 13, 2018 9:27PM PDT

I am a PC idiot.  A senior one. Using W10, Google Chrome and Avira security.
Lately my PC displays note about reload by NTAUTHORITY\System in 4 min.  This keeps on repeatedly. Help, please! 
I took my PC to a shop, they reinstalled W10 twice, but that thing is still alive.
Please, remember -- I am the opposite to a PC wizard... Sad

Can you tell more about that "note"?
Does it appear after a clean install of Windows 10 on an empty hard disk without installing anything else?

Some more category of malwares: Trojans, bots, spyware, adware. Malwares can be used for different intentions like stealing data, stealing money, etc.

Their are ways to be safe from these Malwares.
Installing an Antivirus.
Keeping the Firewall on.
Updating the OS regularly.
Browsing only safe websites.

To be safe from malwares a good, updated antivirus can be installed. Antiviruses also have types, a total - internet - security type of the software should be installed.

A computer virus is a type of malware that propagates by inserting a copy of itself into and becoming part of another program. It spreads from one computer to another, leaving infections as it travels. Viruses can range in severity from causing mildly annoying effects to damaging data or software and causing denial-of-service (DoS) conditions. Almost all viruses are attached to an executable file, which means the virus may exist on a system but will not be active or able to spread until a user runs or opens the malicious host file or program. When the host code is executed, the viral code is executed as well. Normally, the host program keeps functioning after it is infected by the virus. However, some viruses overwrite other programs with copies of themselves, which destroys the host program altogether. Viruses spread when the software or document they are attached to is transferred from one computer to another using the network, a disk, file sharing, or infected e-mail attachments.

Computer worms are similar to viruses in that they replicate functional copies of themselves and can cause the same type of damage. In contrast to viruses, which require the spreading of an infected host file, worms are standalone software and do not require a host program or human help to propagate. To spread, worms either exploit a vulnerability on the target system or use some kind of social engineering to trick users into executing them. A worm enters a computer through a vulnerability in the system and takes advantage of file-transport or information-transport features on the system, allowing it to travel unaided.
