boc425.exe block hook msctf.dll [Resolved]


I think I have done everything possible to get CFP to treat BOClean as trusted, but on startup CFP Defense+ blocks tens of thousands of suspicious attempts, and the log file shows this:

c:\comodo\cboclean\boc425.exe block hook c:\windows\system32\msctf.dll

And this doesn’t stop - it just keeps racking up blocks.

Any help would be appreciated.


Hi ff,

Go to Defence+/Advanced/Computer Security Policy:

Find the entry for C:\Program Files\Comodo\CBOClean\BOC425.EXE: Right click on it and choose “Edit”
Now click on “access rights” and next to where it says Windows/WinEvent Hooks click on “Modify”
You will get a new Window with allowed and blocked hooks.Have a look in the blocked section to see if msctf.dll is in there.If it is Remove it and “Apply” to close all windows.
Alternatively have you tried removing the entry for BOClean from Computer Security Policy “Apply” to close windows and let D+ learn it again.

Regards Matty

Riggers, thank you very much for the advice - removing the entry for BOClean and letting D+ learn it again did the trick.
