Let's say, somehow a malware is present on your filesystem (e.g : BusyWinman Malware).How would you secure your files against being transfered by such a malware to somewhere else?Please, describe the most restrictive case.
Securing files against malware

Once a malware has made it through your system, the system must be considered compromised and unreliable. Therefore any mitigation countermeasure, e.g. blocking connections to specific IPs, is unsafe. Unless you reverse-engineered the malware and have acquired a perfect understanding of how it works, you can never be sure it won't pop up something bad again one day.The only good option is to reformat your machine i.e. nuke it from orbit, and reinstall again.
