A resident virus, as the name suggests, is a type of virus that resides in the Random access memory (RAM) of your computer. Every time you open a certain program or a file, resident virus gets activated. It will spread throughout the system through programs that are running. When users multitask and run several programs at the same time, the resident virus infects all those programs if activated. For instance, if resident virus activates when you open PowerPoint program, then it will infect all other programs that are running at the same time.

It is very common type of virus and usually gets detected and deleted by antivirus scans; however, you can still remove resident virus manually.

How to remove a resident virus manually?

To know which virus is being problematic, look up on internet for those specific error messages you are receiving. Get the error code or the virus’s name by searching through search engines and note down the name of that particular virus. Now you will know what you should find in Window’s registry.

So, be sure you do not mess up with Windows registry as any wrong edits would have serious consequences for your computer. If you are unfamiliar with how windows registry works or just got to know about it when you read in this article, then be more careful to edit. Follow the steps below:

1. Press “Ctrl+Alt+Del” and click “start task manager.” Go to the tab “processes” and find any suspicious viruses named resident virus or something like this.
