Terminal infected with Virus.

Scenarios where the issue occurs:-

Viruses are spread from one computer to another in the form of executable code. When these executable codes are present in Network, Internet or Removable mediums such as a Floppy disk, CD, DVD or a USB Drive, the user system gets infected by them when they are trying to make any activity from these infected locations.

Viruses can be divided into two types based on their behavior when they are executed.

  • Nonresident viruses: Which immediately search for other hosts that can be infected, infect those targets, and finally transfer control to the application program they infected.
  • Resident viruses: This does not search for hosts when they are started. Instead, a resident virus loads itself into memory on execution and transfers control to the host program.
How to Identify the issue:-

Steps to identify a virus infection are follows:

  1. Check if the task manager and registry is accessible when enabled (should not disappear when started).
  2. Check if the Folder option is accessible.
  3. Folder inside the folder should not be present in exe format.
  4. Abnormal Behavior of the Operating System.
  5. CPU Utilization may increase.

  1.   Check if an Antivirus is installed on the infected machine.
  • If present:
