If you see $sys$DRMServer.exe in your process page. Then you have the Sony Root Kit Installed. Here is the following thing i’ve done to remove such a kit.
1. Find the location where the root kit is installed.
- In Safe mode delete this dir.
Open the registry (regedit)

HIT Key Local Machine and Hit Key Local User there should be a software folder. Go in both and check for $sys$ and del.
