(Sangfor Technologies, 2023)
Viruses are malicious software that copies itself and spreads to other computers. (Sangfor
Technologies, 2023) Its harmful code joins itself with programs that support macros. Many
computer viruses include multipart, polymorphic, compression, macro, boot sector, and stealth
viruses. Nevertheless, a virus needs a carrier to propagate. It indicates that it moves via
downloaded files from the internet or USB connections. A virus can propagate and spread
throughout the system and any associated networks once it has accessed your device.
Different ways to protect yourself from malicious code:
o
Install and maintain antivirus software
o
Use caution with links and attachments
o
Block pop-up advertisements
o
Use an account with limited permissions
o
Disable external media AutoRun and AutoPlay features
