Clean you mac from MacCleaner/Mackeeper malware in 3 steps.

anti-virus.sh

# 1. List all the daemons running on you mac that are not published by apple.
# Search on google any name that you do not trust.
# MacKeeper has at least one with a strange name.
launchctl list | grep -v com.apple

# 2. Remove all the suspecious daemons.
# You won't be able to simply kill -9, they all restart each other and redownload themselves.
launchctl remove com.malware.something

# 3. Remove all associated files
sudo find / -name "*malware*" -print -delete 2>/dev/null
# Sometimes find failed to actually remove the files, run it a second time to make sure
find / -name "*malware*" -print 2>/dev/null
# If anything still show up
sudo rm -rf /path/to/file/or/directory/to/remove

# If it comes back you have probaly missed one so back to step one.
