Last night I stumbled into the following address:

ztreewin2.rssing.com

The visit has triggered popups stating that

Microsoft Security Client
An error has occurred in the program during initialization. If this problem continues, please contact your system administrator.
Error cods:0x80070426

followed by
Google Chrome

This looks like a miserable rabbit warren to wander into.

Has anyone good advice to offer?

I'm troubled because ZTreeWin, a tool I depend upon, has had its name misused.

Thanks
John
