How to enable USB ports disabled by antivirus?

I think that your ports are blocked because of boot sector virus and malware and it is not because of any antivirus, for you I suggest that you do these steps and give me an acknowledgement of your problem.

So the solution is go to Desktop then right click on My Computer and then go to properties, then click on Hardware profiles and there will be an option called as Device Manager, after opening  device manager you can see all the hardware devices attached to your system and you can enable and disable it , from there you search for USB ports and then right click, you will find an option to enable the USB port if it is disabled, after doing that restart your computer then after restarting check your USB ports and then reply me here again. This is just the basic step or I can say the basic solution to your problem.

How to enable USB ports disabled by antivirus?

Thanks Deepak for your guidance. But this basic solution did not cure my problem. When I enable the USB ports at that moment it gets enabled and then when I restart the computer and again, use the USB ports it is blocked. And after that, I tried not to restart and inserted the Pen drive, when it was enabled but it was not working but it shows that it is enabled but the moment I restart the computer the situation is the same as before.

How to enable USB ports disabled by antivirus?

So this means that your computer is affected by many brutal viruses which are not enabling the USB ports, so this problem can't be solved with a basic solution, you should try editing the registry now because it is the last solution and viruses don’t degrade the registry and the port enabling operation can be done.

I have read one of the articles of Microsoft which tells how to disable or enable the USB ports. The changes should be done on registry keys but it is risky as registry is the backbone of Windows operating system and if you do a mistake or suppose you delete some entries then it is very difficult to bring back those entries and which can only be fixed by reinstalling the Windows operating system. Solution:

To re-enable a disabled port:

1. Start–> Run.
2. Type regedit, and then click OK.
3. Search the following registry key:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesUsbStor
4. In the right pane, double-click Start.
5. In the Value data box, type 3, click Hexadecimal (if it is not already selected), and then click OK.
6. Close registry editor

How to enable USB ports disabled by antivirus?

Hello kunal,

First of all please try logging in as administrator using safe mode and if that do not work than let’s think about the procedures we can do with it. Ok suppose that did not work, now in administrator mode you open run and write “devmgmt.msc” without quote. One window will appear now in that you will see all the devices attached in your PC. Among those you will get universal serial bus controllers option at the bottom of the list. Now double click on that and if you get red cross on those than you will understand those are unable to connect any external device. Now right click on those options and select enable. Problem solved.

Thank you,

Riley weaver.
