Need Help! Malware alert on Websites

Hi there,
I have 2 affiliate sites at the moment, 1 is still upcoming but they are all on same hosting server with Bluehost. They are all coming up in google as "MALWARE SITES". When I use google chrome and try to go direct to it , it's blocked. On IE and Firefox it works, but the thing is, in Google searches it says THIS SITE MAY CONTAIN MALWARE.
I have done nothing... I haven't even been on my sites for 2 months now because I've been on holidays. I just came bcak the other day and checked my sites to see this on all of them.
Cashash.com
Topfitnessadvice.com
Both are blocked... search them in google and you'll see same thing... problem is this is also hurting traffic and search ranks... what can I do? Has this happened to anyone else??
I'm a newbie so i have no idea but its costing me business, because its even spread to my non affiliate sites on my server.
How do you all protect your servers from hackers??
Need help please, any response will be much appreciated, Thankyou,
Ashton
