Windows 10: Uninstalled a program successfully, however a .sys file is still in my drivers folder but...

Hello,I recently uninstalled a program. When I used the Everything app to search my computer for any remnants of it, I found a .sys file in my Sysrem32/drivers folder.I cannot delete it from the Everything app.When I open the path to the drivers folder, the .sys file is not shown, even after enabling Hidden Items under the view tab.I scanned this folder with Malwarebytes and it does not seem harmful. 1 Is it possible that this can actually be a harmful file, even though there is nothing on my computer related to this aside from this one file?2 How do I delete this file?Cheers

:)

 

How do you uninstall chipset drivers?

I'm installing a new mobo so I need to uninstall the intel 865g drivers to make way for the P35 drivers.

Can't find any uninstall options in add/remove programs and intel chipset inst listed in driver cleaner.

Any suggestions? *Confused

 

What is semav6msr64.sys & Mellanox Drivers?


I noticed semav6msr64.sys on my system earlier today (also via Autoruns), and eventually tracked down the program which installed it - you heard it here first! It's an Intel file, and just coincidence that SEMA Software authored a driver file with the same name.

On my system the driver was installed by the Intel Driver Update Utility Installer, which I'd installed to update my Intel drivers. Uninstalling this program after use doesn't uninstall semav6msr64.sys, presumably due either to a bug in the uninstaller or to laziness of the development team who wrote it. I don't like leaving software package remnants on my system for no good reason, so removed it as follows:

1. Create a System Restore Point in case the following steps cause any problems.
2. Uninstall Intel Driver Update Utility Installer, if it appears in the installed programs list in Control Panel.
3. Rename semav6msr64.sys to semav6msr64.sys.bk [to be deleted sometime later if no problems are encountered].
4. If, and only if, you're comfortable editing the registry, delete the following keys (otherwise just leave them, they'll have negligible effect):

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_SEMAV6MSR64
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\semav6msr64

 

What is semav6msr64.sys & Mellanox Drivers?

Thanks - as I further check, I first disabled semav6msr64.sys using Autoruns then rebooted. I didn't have the first registry key but deleted the second and deleted the driver file. I now have no trace of semav6msr64.sys.
