[Abnormal extension Stillwater-Cottage2b]

Yes, i have this image from this site. I didn't know before that this "problem" is due from image name.

[Abnormal extension Stillwater-Cottage2b]

I found a file on disk:

T.K.---Stillwater-Cottage.jpg

and surely he has something to do with it, but it is strange that the file name is treated as an extension. Possible that it caused by dots in name.

Hi,

 

After analysis of the registry CCleaner informed me that:

 

Abnormal extension
.---Stillwater-Cottage2b	HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.---Stillwater-Cottage2b

 

The entry can be removed but I wondered whether is not caused by a pest. On the Internet, there is nothing about this format. Maybe you know something about .---Stillwater-Cottage2b?
