How to prevent a virus from injecting HTML code and binary code into .exe and .dll files?

Question

Malware

Once upon a time, I caught the Ramnit file virus. In short, the virus infects all .exe and .dll files and adds some VBScript to all HTML documents.
Since the files are not treatable, but very important to me, I want to do something that no one even thought of doing before me.
Task: Prevent the virus from infecting my HTML documents with its idiotic VBScript, which insolently tries to write its binary data to the svchost.exe file.
There is also another task, to release it from RAM memory and prohibit further distribution when an infected file is opened.
PS I don't consider the option "download LiveCD and that's it". It is necessary to cut off oxygen to the virus, in a non-standard way, while leaving the infected files in place.

"I want to do something that no one even thought of doing before me." I want to upset you, they thought. For example, the creators of the OS came up with a restriction of access rights.
