How to track and fence an application in win 10?

Question

Windows

Suppose I suspect that my system may be hacked. What methods can be used to protect the application from attacks and data collection from it? The application is a chat with correspondence and everything that the application receives and transmits has a value higher than the entire Windows system. Run in a sandbox or are there any programs specifically for these tasks?

Answer 1

KIS is very good.
And in the general case, 1 virtual machine is usually allocated for sensitive data. On which there is an antivirus, a browser and a client bank. Nothing else. Moreover, all operations are carried out from a special user.
In addition, configure the application launch policy only from the white list of applications.
The disk is encrypted, unlocking only with a token, it also stores passwords.
This is if it's serious.

Answer 2

From telemetry from Windows? No way, although you can try to block the lists of telemetry servers known to everyone.
From other applications? Running in a virtual machine, where, apart from this application, there is no nichrome.
If possible, transfer it to Linux - Windows viruses are unlikely to work in Vine :D

Answer 3

run it in virtual machine.
