I have a Dell XPS 13 laptop running Windows 10 on which I installed Bitdefender Free 2017 last fall.  Since this is my travel laptop I don't run it all the time.  I turned it on today and Bitdefender Free had turned off automatic protection, showed a big red error "Your system is at risk", and when I tried to run a system scan, the scan failed.  

 

I tried to search for a solution, or at least for an uninstall tool.  It looks to me like Bitdefender has stopped supporting the free antivirus edition, although I see the download link still exists; and it doesn't provide an uninstall tool - its help files tell me that my start menu should have a "repair or uninstall" option, which wasn't there.  I finally decided to uninstall the thing on the control panel; but the file folders are mostly still there.  

 

Right now the laptop is protected by Malwarebytes (paid) and Windows Defender.

 

First, how do I get rid of the rest of Bitdefender?  Second, is Windows Defender now enough on Windows 10, or should I look into other free antivirus tools?  I chose Bitdefender because of a recommendation on Bleeping Computer.

Hi, hedera!
 
Sorry for the late reply, but anyway:
 
I would recommend trying these options, one by one;
 

1. Download and reinstall Bitdefender Free Edition from here: https://www.bitdefender.com/solutions/free.html

 

2. Uninstall BDFE from Control Panel → Programs and Features in Safe Mode, download and use the vendor's removal tools (Paid version, Trial version, Business version) from here: https://www.bitdefender.com/uninstall/ and perform a clean reinstall

 

3. Uninstall BDFE from here: http://www.bitdefender.com/files/KnowledgeBase/file/Gonzales_uninstalltool.exe and run it in Safe Mode, and perform a clean reinstall in Normal Mode

 

4. Redownload BDFE and reinstall it over the existing installation to correct missing shortcuts and registry entries and uninstall it in Safe Mode

 

5. Download Revo Uninstaller from here: https://www.revouninstaller.com/revo_uninstaller_free_download.html and uninstall BDFE it in Safe Mode

 

6. Download and uninstall BDFE from here: https://support.eset.com/kb3527/#removable#top in Safe Mode

 
Information on how to enter Safe Mode: https://www.bleepingcomputer.com/tutorials/how-to-start-windows-in-safe-mode/#windows10
 
Important note: While in Safe Mode, please right-click the BD Uninstall Tools and select Run As Administrator.
 
As for Windows Defender on Windows 10, please read this article by quietman7 on Choosing an Anti-Virus Program.
 
Good luck! :)

midimusicman79

Windows 10 Defender provides the same level of protection against malware as Microsoft Security Essentials (MSE) provides on older operation systems plus enhanced protection against rootkits and bootkits. Windows 10 Defender is just as good as any other free antivirus solution (and probably easier to use for the novice) without bundled toolbars or nagging popups. The key word being "free".
 
I have read several reports of third-party anti-virus software being turned off after folks installed the last two Creator updates so I suspect the failure to scan may be an issue related to Defender.

Thanks to all 3 of you for the responses.  After thinking about this for a couple of days, and reading the recommended post by quietman, I've decided to give up on BitDefender and stick with Defender.  I used Microsoft Security Essentials for quite a while and was satisfied with it, until it developed a bug which sent the full threat scan process into a loop that never completed, which Microsoft never got around to fixing.  My other issue with it is that I know from experience that to reinstall BitDefender, I'd have to uninstall Malwarebytes first, then install BitDefender, then reinstall Malwarebytes. 

 

Midimusicman, I think I'll use your links to pull down the vendor's uninstall tool - thank you! How much of a problem is it that I uninstalled BitDefender from the control panel when not in Safe Mode?

Sometimes the uninstall works more effectively if you first stop and disable the program's service (and associated processes in Task Manager) or perform the removal in safe mode so there are less processes which can interfere with the uninstallation.

Hi again, hedera!
 

Midimusicman, I think I'll use your links to pull down the vendor's uninstall tool - thank you! How much of a problem is it that I uninstalled BitDefender from the control panel when not in Safe Mode?

 
You are welcome!
 
As opposed to in Safe Mode, in Normal Mode, Bitdefender runs and will interfere with the uninstallation, so to use an analogy, in Normal Mode, Bitdefender is awake and active, whereas in Safe Mode it is asleep and passive, and will as such not interfere with the uninstallation.
 
As for how much of a problem this is, if any and you want to resolve it, you should make sure to reinstall Bitdefender as part of the uninstallation process, preferably in the order specified, so you subsequently have run all the BD uninstall tools.
 

...I know from experience that to reinstall BitDefender, I'd have to uninstall Malwarebytes first, then install BitDefender, then reinstall Malwarebytes.

 
Again, as long as Malwarebytes is running, it will interfere with the reinstallation of Bitdefender, so I would recommend keeping that in mind.
 
As a side note, in the past, Malwarebytes used to recommend users to first exit their Anti-Virus in order to avoid that it would interfere with the installation, and I guess that still applies.
 
And please post back with the results, as we are eager to know exactly which BD uninstall tool that actually manages to resolve your issue.
 
Good luck! :)
 
Regards,
midimusicman79
