  Hi
I seem to be having Internet problems (2)

 1. I can not select which wireless net I can connect to. thus my wireless adapter seems to be unable to connect. I will welcome any help.

2 . every so often I get this message (your firewall is sending you a message  about a virus call this telephone number for help. I promptly "close" the message but it comes back saying you don't want to close me do you  and repeats the "firewall" message and then after a period of time will  not close. I have looked for weird programs to no avail, I ran AVAST Rescue disc (8/14/2915 version )
but it did not find anything. again any ideas would help

run malwarebytes sounds like a malicious software is on your computer. 
after you run it reboot then run it again. then after let me know how things are going so i can make sure your infection is cleaned
