Windows 10 desktop icons display weird

Absolute tech noob here. So about two hours ago half of my desktop icons randomly stopped showing correctly. Here's what I did

-restart -clear IconCache and restart windows explorer -tried running DSIM.exe/Online /Cleanup-Image /RestoreHealth (Didn't work, said something about unknown command?) Sometime later the command prompt randomly started to run, which kind of scared me, it's not because of a virus right?

I realized there's a tiny tiny cloud icon on the bottom left corner of each broken icon, and those that weren't corrupt didn't have one.

How do I fix the rest of the icons? Please help :(
