I have noticed over the last several weeks that zoho occasionally is redirecting me straight to some advertiser sites on login. 

This isn't a wait for this to load or skip to where you clicked type redirect either...I go straight from zoho to wherever. 

Usually I actually have to reload zoho.com manually as hitting back or refresh just brings up the same ad again.

Thought I might have a browser hijack or something, but I have seen it on a remote system now as well.
