Windows 7 Wifi Login Web Page Keep Adding Something in my Emails?!

[Jamal]

Hi, Whenever i connect to open wifi (i mean the wifi which is using a webpage to log on) and not do the actual login. Wifi login webpage is keep added in the last line in my every sent or drafted emails! It is always happen no matter what browser or what account as far as it is on the same laptop which is used to log on to the wifi. The emails screenshot attached.

Clearing the cache, cookies, history, or resetting the browser does not work. It is not the wifi problem since it happen in all open wifi, it seems it has something to do with windows feature.

That would be an email signature most likely. Delete the signature from gmail.

In Gmail.

Settings > General. Near the bottom remove or change the signature.
