After installing Avira, my external USB hard drive is not working but it is detected, why?

Answers

Let me give more detail about my problem, before Avira (free one) installed, my USB hard drive (acer 500Gb USB 3.0) is working normally, but after Avira installed, my USB hard drive is not working but USB thumb drive is working. The problem is in Windows Explorer the external drive is detected but when I click on folder inside the external drive it is not responding anymore so I have to disconnect the drive. My external drive is 100% clean from virus or any malicious files so don't say it is not working because it was infected. And because it is important, I have to transfer my data from external drive to the new PC so I have to unsinstall Avira for the time being untill this problem is fixed.

Just have read this and I had just realised that Avira was blocking External Hard disks !!: For two days I have gone crazy on my Windows 10 system. I had a new istall to Windows 10 and had installed Avira AV, but other programs too, so I coiuld not understamd what was the problem. I have blaimed Windows fore thgis: reinstall drivers, doing system restore, removing drivers...to the point of making my Win10 unbootable. Fresh install and can see my external hard Disk, install Avira and here we go again !! I am sorry gentleman: you should have a flag for warning of this issue. I have lost 2+ days trying to sort things out and it was simply Avira and Not windows. Sorry Microsoft guys for the all the swearing done. Not your fault.

I had this issue too! I spent the WHOLE day trying to make my USB ports work. External HDDs and memory cards could not be read. They got detected but nothing happened. Disk Management console said it needed to refresh every time you try any operation on the external disks. I even reinstalled Windows only for the problem to persist because Avira was the firsth app I installed!

I Googled and was directed to this page. I have uninstalled Avira and ALL my USBs are working flawlessly! I can't believe I spent the whole day on this.

I have the same problem here infect I formatted my 500gb external HDD with lots of my personal data from disk management under my computer setting after all of these efforts finally I got problem with avira, first time I selected the avira with the replacement of kysperper total security and this thing involve me in a very big trouble. still I'm finding the solution to connect my externel drives.
