Unregister DLLs:

Tip: this is only a list of known files/locations. You will want to do a search by the name of the file to see if they're on your system.
A while back I wrote a guide to Register/remove DLL or AX files which you will need if you don't know how to unregister these files.

Each file is in several locations so you'll need to search for them and unregister + delete them in every location you find.

acd.dll
anaamon.dll
bs2.dll
bs3.dll
bsx5.dll
bxsx5.dll
bxxs5.dll
oo4.dll
rem00001.dll

Remove Directories:
Windows\bsx32

Clean your Registry:

You should be back to normal IF this was your only problem. I suggest you post in our HJT forum since its not likely that this is your only bug. Read this first
