To remove a Resident virus can be a bit complicated, since, based on the replication module this is one of the most common PC viruses that one can come across. Its main function is to install a harmful code into your device memory which is capable of infecting not only the current programs but also the ones that you download in the future.

To infect a device the Resident virus must find a place in the system’s memory and at the same time should be able to plant a resident code that gets activated on a specific event or function.
