General Wifi starts unwanted...

view story

http://androidforums.com – I really don't know what the problem is but my wifi activates when i don't want it like when i'm at home!!!! I use "Profile Manager" and use a profile where i disactivated wifi but still it starts now and then... how would that come?? Btw: is it normal too that it sometimes keeps saying that there are "open wifi networks" while wifi is off?? Does it scans(all the time) for wifi networks??? (General)
