My users who use Avast continue to say that they get the warning. I tested pulling all the ads from the site and still got this issue from urlquery.net:

Intrusion Detection Systems
Suricata /w Emerging Threats Pro No alerts detected
Snort /w Sourcefire VRT
Timestamp Source IP Destination IP Severity Alert
2013-08-09 08:05:02 174.122.149.143 urlQuery Client 1 MALWARE-OTHER TDS Sutra - redirect received

I’ve since put the ads back up since they aren’t the cause. One ad was causing the earlier warning involving the Russian Business Network IP but I removed that.

I’m at a real loss here. I tried contacting Avast directly but nobody replied.
