All I can suggest is uninstall the useless Symantec and install Avira (it's in the guide)
By the way think of the guide, as a must do, ie follow every step, otherwise you may not get much help.
Tried to uninstall symantec but as soon as it says you have 264 days left in your subscription you may lose it, i hit next, and the program no longer responds. I will try to do the safe mode networking step now.
