For those who are infected by cinficker worm, NO NEED TO BE WORRIED. The windows worm downaduo kido conficker that has infected upto 10 million pcs can be removed using manuall removal method. also removal tools for cinficker worm avaiable over internet
Removal tools are no solution to an infection, particularly not with malware that may download more malware or may give an attacker remote access. One can never be sure what else was modified on the system and thus can never be certain that the malware was removed entirely.
Although as a /generality/ this *may* be true, particularly with complex infestations. However, Microsoft themselves encourages the use of their MRT as an accepted remediation practice for Conficker. You're *NOT* wrong. But in this case though, flatten & rebuild is overkill.
Is it? The system could have been infected with a different (not yet known to the public) Conficker variant. It could be infected with other (undetected) malware on top of that. Unless you are really, absolutely,
100% sure that the infection was with Conficker.X, only Conficker.X and nothing but Conficker.X, your only safe way back to a clean system is to flatten and rebuild.
Microsoft can recommend their removal tool all day long, that doesn't change anything at all about the fact that all of these tools make the assumption that the compromised system is infected with nothing but what they detected. An assumption that may be right, but may just as well be wrong.
