While you may come across a single file of malware which you are able to delete, this is unlikely to be the root cause of the malware infection within your device, and it is difficult to tell whether it would have spread laterally to other devices across your network. This is why simply deleting one file will almost never get rid of the malware across your device or your systems, and is why best practice for dealing with malware attacks, particularly if you are not an IT or technology company, is to have a partner run a System Review or assessment to determine the extent of the damage that may have been caused, and to eradicate the malware entirely.
