|Virus file names are often a mixed bag of letters, as given. To see them you will have to go to Folder Options > View and temporarily set to show hidden files and probably show protected system files too. Best not to leave things that way long term.|
I have never found anything crucial in temp folders so in a general way there should be little harm deleting them. Unfortunately when viruses are around you can never be certain that they might be programmed to react badly from an attempt to remove their files, so it has to be at your own risk. However if you have somehow disabled them without any issue it should be OK to delete them.
It would be worth further checks for a virus after their removal. Use you virus checker and also MalwareBytes freebie (which is good at finding and fixing what AV's sometimes miss).
We all live on a ball.
