Hence, keep in mind that having security software does not guarantee full protection. The majority of the prevention still lies in being cautious of users, and therefore, we are providing the following information as guidelines to protect the computer from virus infection.

Avoid Malicious Websites

Do Not Click a Suspicious Link

Be Careful When Downloading Files

Cracked software, serial key generators, and several freeware are seen as another method that spreads the Win64/Spyboy!MSR virus.
