Is OCSetupHlp.dll a Malware and How to Remove it

Several antivirus, including Malwarebytes and AVG, label OCSetupHlp.dll as a threat or malware. The DLL file is linked to OpenCandy, a known PUP (Potentially Unwanted Program) that comes bundled with other programs, such as uTorrent and CDBurnerXP.

OpenCandy can change the user’s default browser or homepage, install malicious extensions, or share the browsing history with third parties. Users also reported high CPU usage, sometimes in the range of 70-90%, after OpenCandy was installed. Both OCSetupHlp.dll and OpenCandy pose a threat and should be removed from the PC.
