I would not use it based on the review I have read about BOclean.
Have a look for yourself.

2.1 Review: Comodo BOClean V4.23
When I read that Comodo had acquired the commercial security product BoClean and were making it available for free [1] I was excited. BOClean is a malware memory monitor with a good reputation and a strong following. The possibility of combining this with a good freeware scanner like AVG Anti-spyware sounded like an attractive possibility. The name BOClean derives from the fact that BOClean originated as a specialist cleaner for the original Back Orifice trojan. Over time its capabilities were extended to other trojans and then to malware more generally. This history is not irrelevant. BOClean is by design an anti-trojan monitor with some other capabilities added on. Despite my high expectations BOClean performed poorly on testing. Naturally I couldn't run any of my normal scanning tests as BOClean is only a memory monitor and has no file scanner but on the other tests it performed terribly; arguably the worst performance of any product I have tested. You can read my lab notes here [1] but it suffices to say that BOClean missed too much and protected too little. Perhaps the worst aspect of its performance is its total lack of self protection. It can even be terminated by Windows Task Manger. If that's not bad enough BOClean is on the hit list of many of the security software termination programs that form an integral part of modern malware. Its lack of protection and slow response make it a sitting duck. More accurately, a dead duck. I hate to disillusion BOClean's many ardent fans but BOClean, like SpyBot Search and Destroy was a once great product whose time has passed. I simply can't recommend it for general use against modern malware. Hopefully the new owners of BOClean will develop and enhance the product; it really needs it. Freeware, all Windows versions, 1.34MB.
