Malwarebytes will NOT find twunk_32 virus issues.
Twunk_32 is a 16bit to 32bit on the fly conversion tool for windows. Recent malware programs use this to run trojan scripts. If you have high system usage by twunk_32.exe I recommend taking ownership of the file and renaming it to twunk_32.old.exe. Then see if any programs are affected by it's loss. It is not essential to windows function but other programs may use it.
Found it in the "Windows" folder on my hard drive, its probably important so I didn't touch it.
When I want to play the FiFa OnlinE 3,the game is lagging.So I check the Task Manager,I delete all process (except the importances).So I also delete the Twunk_32.exe and the game is not lagging anymore,then about 3 minutes,the game is lagging back,I check task manager,and the twunk_32.exe reopen automatically.
It is running about 30 times according to task manager, and appears to be consuming memory.
