I am trying to install anti-virus software on y laptop. I keep getting the we" can't download a file check internet connection " messages even though I 'd spoken to spoke to my provider only half an hour earlier about another problem with this device and was told my internet connection is fine. I have no problem opening up browsers either. I have a very old wall socket and all my electronics have to go through a powerboard. Nothing can be plugged directly into the wall. Any suggestions?
