Without much more details I'm afraid that all that can be suggested is a thorough check for spyware, viruses and such. Let me suggest MBAM, Superantispyware and Housecall online antivirus.
Maybe if you tell more ...
Why do I get a pop-up saying I'm not connected to the internet while trying some functions and others are fine? My system is a little slower accessing websites. Is it something I did while playing an "IT" which I'm not?
thank you, David M. Simisky
