While not specifically photography-related, I thought I'd post this information, as all webmasters and people running websites should be aware of it, as AVG LinkScanner could be causing additional bandwidth usage on your websites, and falsely inflating your website hit counts.
Also, anyone with AVG Anti-Virus Free 8.0 needs to be aware of this behaviour, that it will consume additional download quota as LinkScanner queries every result on a search engine results page, and that it is having a negative impact on websites.
