Parse error message - JS/TrojanDownloader.Iframe.NES - how to fix it?

I changed to a new host back in May but last couple of days my website https://www.day2remember.com.au won't open, instead this message is showing:

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ',' or ';' in /home/day2reme/public_html/index.php on line 107

Can anyone tell me what I need to do, to permanently fix this problem. I'm using the latest version of Zen cart

Thanks in anticipation.

I should have mentioned, my friend fixes it, but doesn't last long and it happens again. Also when I tried to open it, twice NOD32 warned me that the trojan virus has infected the index.php file. this is the message NOD32 displayed:

12/06/2009 12:21:28 PM IMON file http://nyfilmlife.cn:8080/index.php JS/TrojanDownloader.Iframe.NES trojan Connection terminated

What should I do???

Put your cart in maintenance mode and contact your webhost immediately.

Thank you. I had a new template installed yesterday and it hasn't happened today.. I have contacted the webhost, however haven't heard back from them. See what they say. In the meantime, I've turned on down for maintenance mode on.

By the way, I love your recent zen cart project (dog store). I hired someone thru elance to re-design my old site. I wish I would have gotten a quote from you before :(

Thanks for the compliment =-)

You got it right, its best to make sure you are clean before reopening your store. If Google finds these issues on your site it will hurt you very deeply and for some time.

You can check your shop here to see if Google knows already.

Pleasure!

I checked it and it's not. So hopefully it stays that way. Thanks for all the tips. I've bookmarked your site, one never knows...one day I might need a re-design again :)
