Thank you for your advice. 

Spare (dispensable! i.e. with non-important data) SSD 120 GB with a fresh installed (i.e. "just now", from scratch! just before use!), is always a good idea. If you were infected ("the main system") by novel virus, no antivirus will find it, and you don't know what kind of backdoors were installed on it (if it was truly virus/hacker attack).. Viruses/hacker attacks disable antivirus and firewalls. They can do that because they gained admin/root privileges.

It is better to not too accustomize with an operating systems..

I am swapping Linux 4 times per year, and in between there are special "erase all to permanent zero", one per month or so..

Learn how to backup entire browser (cookies etc.) from file system.

It should be in hidden folders:

%USERPROFILE%/AppData/Local

and

%USERPROFILE%/AppData/Roaming/

(both are important!)

Copy them from Linux Live pendrive to another device e.g. pendrive.

This way you can even use web browser data (logged sessions) from Windows on Linux machine, and vice versa, if you did everything properly.

Copy them in an appropriate places on a new fresh system..

You need to create Linux Live pendrive first, somewhere (obviously not on compromised machine!)

(Linux can read Windows NTFS files and folders, even without admin privileges, attempt of reading Windows NTFS folders on Windows, which are only accessible by admin, will fail)

Most people are never ready for "Winter is coming".. You don't know when winter is coming.. Unlike true winter which is pretty regularly (so people started making food for it)..

Damage of disk, this way or another, will happen sooner or later..

Thank you for your advice. Sadly that is far outside the realm of possibility for me at this time. I think the problems i am having are a senergy of a bad mouse and unused files cluttering up my computer. If it is a virus as you say then I am screwed but I know you guys will miss me.
