So I just encountered a Russian virus that completely changed my language, installed programs, etc. until I was unable to get into my account via incorrect password. No biggie, I had just started on this desktop a day ago. Currently restoring my computer with a windows 10 disc, until I realized a change. Last time I partitioned and convert gpt to install windows 10, it created 3 different drivers which weren't all that much space. Now, there's only 2 other drivers and one of them takes up over 700 gb of my data. What's the cause of this? Is this still the Russian virus working on my computer, or is there something else going on here?
