Aircrack part of a software suite to capture wireless packets and analyze them for patterns that are used to decipher keys to a variety of different kinds of wireless encryption protocols. I've used it to do security audits with great success. It sends transmissions that cause connected computers to try and reconnect by resending their network key. When it has captured a set of packets (say 20,000 or more ACK transmissions) part of the suite uses an algorithm to find anomalous parts of the transmissions and extract a key. That last part will eat up some processor time for sure, which may be what you're seeing.
So, yeah, it's bad and you need it gone. Look in your tasks for an instance that's taking up alot of cpu time and that filename is the keyword you need to search for online to find a possible fix. For all this to work, a specialized driver must be installed to allow the computer to inject and listen for the packets mentioned above. I would uninstall your wireless device first, then find and reinsall the latest driver version on the manufacturer's site. That might do it, but it probably not going to be that easy.
