I have this problem, where my c: drive always gets filled-up, and when I transfer files, I see a bunch of files with these names: e0223fsd.au or something. These files are hidden on my pc, and just some time ago, it had 0 bytes although I cleared-up space before that! Yes, I use an anti-virus. I have windows 10 home 64-bit. Please, I need help. Resetting my pc Is just pain. Thanks.
