So I don't know what it is, but all of my stuff turned into white pages with red and blue blocks in them. First it was the 0_DECRYPT_FILES thing, then my extreme lag, now the pages. I think I got a virus that just implanted itself somehow. I didn't even dow blows anything recently. I can't open Windows Defender, my mouse ALWAYS has a blue loading circle beside it, and some MRT thing pops up when I try to open certain things. I can't uninstall certain things, either. I need some help bad.
