... scanning my computer now. It could be a false positive, the scan is almost done and picking up nothing. Haven't run malware scan yet. Never had my anti-virus alert to anything on here before.
Full V-scan and malware is done and detected nothing, no problems with any other web pages or anything either. The URL seems to be a visual basic script for burst media ads, could be related to your issue or could just be an Avast false positive, have had that happen before a long time ago with a different site.
