I have Mcafee installed on my PC and it is updated daily. A couple of days back, when I came back home, there was a popup of Malware detector on my machine. I quickly uninstalled it and ran a quick scan of my PC. During the first scan, my PC got rebooted automatically. I ran another scan and it gave some infections (around 15-18). Mcafee managed to remove all the infections except one. Now, whenever I scan my PC, I always get a rootkit trojan d!rootkit NTOSKRNL-HOOK. Every time Mcafee says that it has deleted this infection, but with the next scan I can still see the infection. There is no file path mentioned in the scan result.

Now, I can see IExplorer.exe lauched everytime in the task manager (there is no IE instance opened on GUI, its only on the background).

I have a securom service active on my PC which I believe to be the cause of this trojan? I want to remove securom and all related services.

Can someone please help me remove this trojan?
