Hi krypinaturen, welcome to the forum 
First,
Please can you modify the link, to prevent others potentially becoming infected. (change http to hXXp) Thanks.
I can’t see any scripts that would cause an alert.
I imagine that the site is blocked by the network shield because it was previously hacked, there were a few cases of wordpress blogs specifically being targeted. The sucuri blog covers it quite well.

You will have to report it to avast as a False Positive before being removed. That can be done by the online form:
http://www.avast.com/contact-form.php?loadStyles
Choose: Report False virus alert on website and include any information that may help. (A link to here may not go a miss either ;))
Virustotal.
For whatever reason, ClamAV is alerting on the script included at about line 748…I don’t really know why, or whether there is any real merit in the detection (I am guessing that it may be a FP)
The UnmaskParasites warning about the script ouside of the html block.
I don’t think this script is bad per say (no hits on VT), I think that Unmask is just warning about the fact that it is not in the right place.
Generally there shouldn’t be anything after the closing html tags ( )
