Its time you updated your signature.

Go to PROFILE then Modify Profile then Forum Profile Information then Signature: and put information about your system just like my signature about your system just like my signature so that the helpers can offer pertinent advice.

Comodo is the best application to remove Internet Connections when you do not know how to use it.
