你的网站安全吗？普通网站也能被黑？Bluehost竟然要收$339.98修复？

今天登陆自己的网站，发现登陆不上,最后发现原因：
Your web hosting account for XXX.com has been deactivated, as of 2016-01-05 14:17:25.
Reason: terms of service violation - malware/virus.
For more information about this account, please call 888-401-4678, option 5.
询问bluehost.尽然要$339.98修复。2000多人民币，费用太高了，网站做的不算好，但偶尔也会有询盘。小伙伴们有没有有遇到类似情况吗？有好的解决办法吗？如何保障网站安全。

这是和bluehost在线客服的部分聊天记录
