Thanks…it all sounds rather technical to me. I cannot take a screen shot and include it (my Dell is quite elderly, like me ;-)), but I can tell you part of the file name that has been detected. Here it goes:

??\c:\Documents and Settings\All Users\A…(A49ABC0B-3F5B-40FE-

It’s files like these that Avast continues to find. I have to tell you that I never click on any link that is not a trusted site (virtually always machine embroidery related) on this computer. I do have Malwarebytes on here as well as well as MS’s own type of security. And as far as the emails being sent out, they are sent out to a small (say 4-5) number of people in my address book, and always the same ones. If they had actually got into MY system, my guess is that they’d be picking up a heck of a lot more of names in my address book. I wonder if they didn’t get into someone ELSE’s system and picked up on an email I might have sent to those 5 people. It’s always the same group of people, though I certainly send out to far more than those. I also get messages from myself. Comcast tells me to change my password, but I asked if they think someone actually got into my email account, and they say no. Argh! Sure wish these spammers would get jobs that would keep them busy! Any help you can give me would surely be appreciated. And why do these files that Avast finds “suspicious” start with "??\c:"? Thanks!
