I have McAfee 7.0 Virus Scan. It keeps disengaging so I have to go back and put it back on. What would cause this as I want it on all the time? Also I have SBCYahoo as my dial up internet service. I am having trouble replying to e-mail messages. I have to go bak and use Outlook Express to respond as the SBC has suddenly stopped being able to send. The line at bottom goes halfway across and then it says it can't send. Can anyone help?
