Recently I ran a Malwarebytes scan on my Windows 7, it identified a DLL file called 'XHffS.dll' as part of a trojan in the System32 folder, it then did something on the file but never remove it. After I rebooted my laptop, a message starts to pop out everytime I start Windows, saying something like "unable to run XHffS.dll, it is not one of the system's dll file". It's such an annoy keep seeing the pop out message, so i've been trying to delete it but it is untouchable. I've tried software like Eraser to unlock it from processes but it says that no locking handle found, and still fail to delete it.
Does anyone have a solution on this? Appreciate your help very much!
