Since approximately the time I reinstalled Avast 6.0 (that is, Avast's support tech did it remotely), about a week ago, my Windows Mail keeps on deleting and then re-receiving all the emails that had come in since a particular date and time. The Delete folder that I had emptied is full again, and none of my sent or forwarded emails are showing in the Sent Folder.
Since that same time, my Firefox browser has been frozen too - that is, after I've turned the computer on and open the browser for the first time, I get the same error message - something like "Firefox has forgotten your tabs and windows." Then it shows the windows that were open at a particular time and offers me the choice to try to reopen them or to start a new session.
These two things happen every time I restart the computer.
Meanwhile, also new behavior - the Firefox browser window is outlined in red, as are all emails I compose. I think this has to do with Avast's Sandbox. I tried disabling the Avast email scanner, restarted the computer, and those same emails came back in again.
And every computer process seems slower than it was before.
Does anyone have any ideas what is causing these issues and how I can repair them?
Thank you,
Susan
