As you should be aware, the items on that right-hand column are completed it CBO has to deal with a malware. Those items are there to address possible traces of the malware, so that the system can be returned to a verifiable clean state. There are times that malware leave traces in these areas, and may be replicated by the system if there backups created and restored after an infection. Thus, just like reformatting, the only way to know that it’s clean is to clear it out completely. This poses a problem for users who have custom HOSTS files and things of that nature, but for the “average joe” IMO it should be fine.
For the second item, when you say it’s still showing in tasks, what executable are you referring to? BOCore.exe, or BOC423.exe?
As for ccleaner, I’m not sure exactly what you’re asking… are you wanting to know if there is a conflict with CBO, or what exactly?
Heh, you call that old and not “speedy”? I have it running on my IBM (mfg’d in 97, I think) PC 300PL, a P3/500MHz and 640 MB of RAM. Hasn’t disappeared on me yet. And if you want “old and not speedy” there you go (at least, as compared to your 2.2GHz machine…)
