in C:\windows\system32 I have found 54 files named 틃叫善; In windows explorer this file name is displayed as 3 squares followed by a semicolin. They range in size from 93210 kb to 102544 kb. The date modified runs from 9/2/3013 to 11/18/2013. File properties produces no information.
Can you tell me what these files are and can I safely erase them?
