Windows 10: Bitdefender detecting "resident" autorun.inf virus?

I've been experiencing some _extremely_ unusual things in regards to my windows installs and Microsoft account, and I'm quietly hoping that someone far more knowledgeable than myself might be able to allay or confirm some concerns. I started experiencing some strange account activity some time back. I don't know if it might be somehow related, but it was shortly after I experienced a break in to my home. nothing appeared to have been stolen Passwords began "magically" changing, and my Microsoft activity showed someone taking potshots at guessing my password - non stop - every twenty minutes

:)

 

How can I remove this virus remnant?

I was also going to suggest Autoruns.

Check to make sure it isn't attaching itself to explorer. It should be the 3rd thing listed in Autoruns, the listing for the Shell. It should just be Explorer.exe. If it is anything else, that might be your problem.

 

Windows Defender realtime scanning will not switch on - it detects another anti-virus product.

Windows Defender realtime scanning will not switch on, and the message suggests there is another anti-virus product present but if there is it does show up in Window 10 UI.

The long story is that I am troubleshooting a problem with application software. The manufacturer suggest removing Bitdefender because there product is incompatible. I thought I would give this a try, if only to element Bitdefender as a cause.

Firstly, I upgraded from Bitdefender 2016 to 2017 to see if that made a difference. The application still failed so I decided to try removal.

• I used the standard uninstall to remove Bitdefender 2017, rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
• I download the uninstall application for Bitdefender 2017, ran it then rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
• I checked the file system and all Bitdefender files have been deleted.
• I check the registry and found a couple of references to Bitdefender Wallet, then deleted these.
• I rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
• I reran the uninstall application for Bitdefender 2017 then rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection.
  

I can find no traces of Bitdefender so I wonder why Windows Defender detects another anti-virus software. I've check other posts but couldn't find additional steps for uninstalling an anti-virus software. Any suggestions?

Windows 10 Autorun?

Hello,

As you are asking whether the security of disabling Autorun/Autoplay option from system settings is the same as disabling from the registry and will take affect in the same way. There is no need to worry about virus threats which usually attack from autorun/autoplay.
If you want to disable autorun/autoplay from registry, follow the steps provided below:

• Type regedit in the search box and press Enter.
• Navigate to the following location: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
• In the right pane of the window create a new DWORD value "NoDriveTypeAutorun".
• Set the value based on the following requirements:
  • FF – To disable AutoRun on all drives
  • 20 – To disable AutoRun on CD-ROM drives
  • 4 – To disable AutoRun on removable drives
  • 8 – To disable AutoRun on fixed drives
  • 10 – To disable AutoRun on network drives
  • 40 – To disable AutoRun on RAM disks
  • 1 – To disable AutoRun on unknown drives
• If you want to disable AutoRun on a certain combination of drives, you’ll have to combine their values. For example, if you want to disable AutoRun on CD-ROM and removable drives, set the value of DWORD to 28.
• If you want to return AutoRun functionality, just delete the NoDriveTypeAutorun DWORD value.

Note: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore,
make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following
