I was using JustHost until they hit me with the SiteLock scam claiming I had malware on a site. Just Google siteLock scam.
HostGator is also one of theirs. Here's a good description of the scam.
SCAM ALERT: How HostGator Attempted To Extort >$200 Out of Me for SiteLock - HermesThemes.com
SiteLock wanted $150 a month just to scan 10 sites. AND THAT'S BEFORE they will do any cleanup.
HostWinds is cheaper, better and will scan sites for free on request or $1.75 a month for constant scanning. All I had to do was ask them to move 2 WordPress and 8 other sites and they did the rest.
