1. with avast 7 the email accounts had to be manually changed by the user, you have to manually reverse that/those change/s in your email programs account settings.

  2. avast 8 was able to work without these changes, but having manually made the changes for avast 7 to work, you still need to reverse those earlier changes to the email programs account settings.

  3. regardless of what you choose to do you are going to have to reverse the previous changes.
