Virus warnings when visiting blog

The blog is: Dailyructions.com

For the life of me, I can’t find anything wrong with the site. I did a system refresh on our shared host (hostmonster), deleted all FTP accounts on the host so there could be no access that way, and looked at the site from multiple computer on my end. My client at Dailyructions is saying that he is getting virus warnings when people go to his blog. I just can’t find any of this.

Any help would be appreciated.

Thank you in advance.
