If you remove all the infection points of the malware, it's gone. Computers are not magic, and you rarely win by being superstitious with them. Most malware are as good as gone once they've been detected and removed by a decent antivirus.

I'm not saying this due to some marketing claims, but just by looking at the results from independent testing organisations like AV-Test (http://www.av-test.org/en/news/news-single-view/17-software-...) or av-comparatives (http://www.av-comparatives.org/removal-tests/).
