C:\All Files from old Dell\My Documents\Chris Outlook\Chris & Lisa Mail.dbx
Something malicious is located in your mail folder. Since I don't want to remove a whole folder, you'll have to be careful with your current mail. Don't click on any unknown link and scan every attachment with your AV program before opening.
When done with reading, empty your mail folder.

As for the other file...

  • Under the Custom Scans/Fixes box at the bottom, paste in the following

:Commands

[emptytemp]
[emptyflash]
[Reboot]
  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done
  • You will get a log that shows the results of the fix. Please post it.
