Install new BD avfree to replace 2020 version

edited May 2022 in Antivirus Free

Hello, I got an information pop-up asking me to update to the new av-free version of Bitdefender (was currently running a 12/2020 version). I clicked the "Download and install" button and the process went smoothly until the final window presented a "Create a new account" button. There was no option to log in with my already existing account so I clicked the Create new account button. The install window vanished and no "new account" page ever opened. I tried clicking the newly installed BD login icon in the system tray to activate the new av-free. It did not function. So I went to the page and downloaded the latest av-free version for Windows and re-installed the program, to try to repair the installation I had already done. This did not work. I still had no way to activate the new anti-virus. I then uninstalled Bitdefender completely. I went from a perfectly functioning 2020 version to NO anti-virus simply for trusting the "download and install new version" request. Now what do I do?! Dan T. [d****]

    Next, contact Bitdefender Consumer Support by e-mail here (scroll down to the bottom of the page):

    with short description of the issue.

    After that, you will get an automated reply by the Bitdefender Customer Care Team, with your ticket number.

    Now, in reply to that automated reply, you can send the screenshot(s) you already took and the log file you already created in the first step.

    Since you are all done, just wait for the support engineers to investigate your issue and find a solution to fix the issue.

    Remember that the screenshot(s) and the log file will help a lot to the support engineers for better and faster investigation on your issue and finding a solution.

    I just wanted to say thank you to Cosmin T, Thomas44, Gjoksi for their kind assistance. Especially, I want to thank mrmirakhur whose excellent, detailed process, after two complete uninstalls and re-installs, finally enabled me to load and activate the new version of BD avfree, which is running without any problem. Bless the BD community forum and thanks again! And thank you Bitdefender for your great software.
