Yes, you can delete them.
What version of avast! do you use?
Do you have any big archives on your disk? Did you interrupt/kill the scan recently?

Could you please try to identify these files? They are created as temporary files during the scanning of archives (and normally, they should be deleted automatically, of course). So, could you maybe run another disk scan and watch for these files to appear (similar files will be created and deleted during the progress - but some of them may be left).

Thanks!

I’m currently running avast! 4.5 home edition…and my last scan was completed, not interupted or killed.

and these files don’t have extensions…so i really don’t know what they are

I know, I mean:
could you judge by their size maybe? How big are they?

What “file manager” do you use? Windows Explorer, or something else (such as Total Commander?)

i use win explorer, and the files are all between 300mb and 700mb

Do you know of any similar files on your disk? (about that big, packed inside of archives like ZIP, RAR, …)?
If yes, could you try to scan just the specific file/folder to see if a new unpXXX file is left in the TEMP folder?

so, I scanned a 300mb rar file and a new file did not appear in that folder…regardless, i just deleted the files anyway…I needed that space badly…Thanks for all your help anyway Igor!
