deleting files?

dunno why but there are some things that i absolutely cannot delete. sometimes i just cant delete it or sometimes if you block it with comodo you cant delete it… but this is something not blocked i just cant plain delete it and id love to know why.

If not under Blocked files, is it in the AV’s Quarantined files?.
