Another McAfee horror story. Never could get right following an upgrade. Their technical support is in India. One of them (good English and patient, no quarrel there) was on the phone with me for three hours. Another spent two hours with me. Each time, the system refused to load the next time there was an online revision.
Two local technicians tried to help, one of them talking with a McAfee technician in India.
We gave up. It took a while for a technician to remove all traces of McAfee. I ordered and he installed Norton. Their updates don't interfere with what I'm doing- just a little box with the announcement and finished in a few seconds. A weekly sweep of all files just takes about 10 minutes. My out-going Email is checked as well as incoming.

A while back I received a daily email with a virus, the sender listed differently each time. I isolated and purged with Norton, not opening any of them. A technician (a friend) checked my habits and concluded it was probably someone at Mudcat who had my email address and became upset at one of my posts. I changed my address and I will never sign-up with any group again, although I miss swapping info. with some of the members here.
