On my desktop this evening the above named folder has appeared.
I have no idea what it is, I have done a search on Yahoo! and found that there is a WinStat for Excel and a WinStat that is also a trojan.
I have tried to delete it but cannot, getting the message that I cannot delete the file as I do not have permission to access it.
properties gives me no information other than where it is stored, in Documents and Settings, and that it is an archive file. I have tried to delete it with the delete function in Windows, and with Norton. A virus scan of the folder indicates no virus but I am wary of items appearing that I know nothing about. I have also ran Spybot and AdAware and they indicate nothing is wrong. It is indicated that it was created at 11.53am today, however, the PC was not switched on at that time, and my PC is functioning perfectly.
