I am very glad we are in contact again. My computer system is not showing any problems now. In fact, it did not show any problems when I had the infection; it was MBAM which identified the PUM but could not get rid of it when my computer restarted. I had stopped other attacks in the last few weeks either with AVG or MBAM getting rid of them, all except this PUM. I also had emails sent out in my name to my contacts which I did not know anything about so I was very worried that other problems might arise. I have one question about the log. It shows Norton 360 but that expired several months ago and I did not renew it. I thought I had removed it from my computer and it is not listed anywhere. Should I try to get rid of it (if so,how) or can it be left? I have AVG in its place. Is it possible that infection can be reintroduced from video clips which I have downloaded and saved to a memory stick when I play them? I look forward to your response.
