Had a similar problem with the McAfee anti-virus people
One day a client contacted me to say he couldn't download the software on my site as his McAfee anti-virus software had flagged my site up as hosting malicious content. Needless to say there was nothing malicious on my site but getting into touch with McAfee and getting them to remove their false positive was a nightmare and took more than a week. During which time the rumour mill got to work and I noticed someone had mentioned the "McAfee says there is malware on my site" in an internet forum and downloads of my software dropped noticeably. Eventually McAfee removed their "malicious flag", providing no explanation or "sorry about their mistake". They just ignored my requests for what they'd done wrong.
