Avast isn't the only one thinking this site is at least suspect WOT has it as poor reputation, image1.
However, I didn't get an alert on the main domain, but visiting the toolbarservice sub domain results in two alerts by avast (image2&3), on image2 there is a redirection to hXXp://toolbarservice.freecause.com/2.6/.
This scan has two detections,
http://www.urlvoid.com/scan/toolbarservice.freecause.com/, the one from WOT plus this one,
http://www.avgthreatlabs.com/sitereports/domain/toolbarservice.freecause.com/Nothing found here though,
sitecheck.sucuri.net/results/toolbarservice.freecause.com/.

You can ask for it to be analysed/reviewed:
- There is an on-line contact form,
http://www.avast.com/contact-form.php?loadStyles for: * Sales inquiries; Technical issues; Website issues; Report false virus alert in file;
Report false virus alert on website; Undetected Malware; Press (Media), issues.
- If you are reporting an FP, then you get another input field open (image4), click Browse button and navigate to the file or enter the web URL for the site you wish to submit for review, etc. A link to this topic also wouldn't hurt.
