I found this file in c\windows\prefetch and is visable. I don't know what to think
"neutral" as in it's a part of windows but as one guy stated before me, there's a virus with this name too. if you have more than one then congratulations, you're now an owner of a virus. I have one in the system32 folder, can't delete it, can't end the program, can't do anything with it on my own. ( PS. the one in the drwtsn folder is the legit one.)
this file is a known copy virus if theres another location of the file instead of the windows32 folder you should delete it now just so you know because thats the whole reason why its dangerious:)
it was worst the same me, it's very annoying for screen freeze when use USB/CD/DVD, I find deleted to 'drwtsn32.exe'
Check the pins of your hardisk, see if one or more is broken
Every time I close my system I get this 'dwrtsn 32' message saying that it has tried to access the system but found that the system was closing down. It then takes several tweaks,pressing of delete buttons etc.,etc., to close the system down. I have had an operator from a national computer engineer company to look at it but he was unable to do anything about it.
