How do I perform a manual reinstallation of my Avira Antivirus product?

The described procedure should only be applied if a conventional Avira uninstallation via “Control Panel → Programs and Features/Uninstall a program” fails.

To perform successfully a manual reinstallation of your Avira Antivirus you have to perform first a cleanup of your current Avira Antivirus.

I. Clean your system

1. Delete residual Avira files

  1. Boot your Windows System in Safe Mode.

  2. Make sure that your folder options are set as follows.
    Click: Start → Control Panel → Folder Options → View → Show Hidden Files and Folders → OK

  3. Delete the following folders if they exist:
    • C:\Program Files\Avira
    • C:\ProgramData\Avira
    • C:\Documents and Settings\All Users\Application Data\Avira
    Hint: There is no action required if these folders do not exist.

  4. Boot your Windows System in Normal Mode.

2. Clean your registry

  1. Download Avira RegistryCleaner.
  2. Run the downloaded file.
  3. Click Read Keys and confirm with OK after the scan.
  4. If any keys are found, enable the control box "select all", and click Delete.
  5. Confirm the next prompt with OK.

3. Reset the Windows LSP (Winsock)

This step is only required if your computer is running a Windows 7 operating system.

Windows 7
  1. Click Start → All Programs → Accessories.
  2. Right click "Command Prompt" and run it as administrator.
  3. Type the following command in the command line:
    netsh winsock reset
  4. Press Enter.
  5. Restart your computer.

II. Reinstall your Antivirus
  1. Log in to Avira Connect
  2. Click in the left menu panel the Subscriptions button.
  3. Search for “Antivirus” and click Install.
  4. The previously acquired Avira Antivirus package will be reinstalled, and the license will be activated automatically.

Comments have my money, but I do not have Avira Anti-Virus Pro!
I can get nowhere with your downloading procedures.
It would not accept what I think was the activation code.
It would not accept the security codes, after numerous attempts.
I even had to reset a password which I had not yet created.
Also, your instructions for downloading the Registry Cleaner and the Avira Pro installlation file don't make sense. Why not run either file? Why download them? Not that I would now. I am too unnerved by my experience so far.
I'll probably ask for my money back!

I have paid for the pro also. I have the activation code however i can not install. I have followed the install instructions and now what????? I have folders on my desktop....... and.....????? Nothing is happening and no folders are opening to anything. When I double click on the supereasy driver download file it says it can not be extracted with this program. And when I double click on the other downlaod file it saves it to dek top and that's it. Can anyone please help me???

After 2 weeks of hassle, (purchased code on 11/16) I finally have have Avira Pro properly installed on my desktop. The license says I can install on up to 3 PC's. When I try to install on my laptop it says the program is already in use. I have spent a lot of time and aggravation trying to install a simple program. I have never had this much trouble with an antivirus program.

Avira explains all you need to do - Activate your product via internet by the link in letter from Avira. They says it will be automatically updated within 3 days. If you do not want to wait you can manually upgrade your antivirus.I did just that.. I hate to wait. Actually, I think Avira is doing wrong by making such a complicated way to install the purchased product. In addition, it seems that there is no one from staff who reads the user's messages .

Well I opened Avira Free and click on HELP - Licence Management, input the licence code click Migrate now and confirmed current user and all I got was a pop-up telling me "Unable to read Control File" ... totally hopless ... I tried to install by download etc several times, including uninstalling all Avira beforehand to no avail. Even had difficulty in reinstalling Avira Free ... and all this over some 5 hours! Exceeding fristrating and disappointing. Have left feedback with Avira (as requested post uninstalling) though I doubt I'll get a response. Wonder if I'll get a refund?
