- LinkScanner – The patent-pending LinkScanner technology acquired from Exploit Prevention Labs and built into most AVG products, provides real-time updated protection against exploits and drive-by downloads. LinkScanner includes : Search-Shield – a safe search component that places safety ratings next to each link in Google, Yahoo! and MSN search results; plus Active Surf-Shield – a safe surf component that scans the contents of a website in real-time to ensure it’s safe being opened. Concerns regarding web analytics have made LinkScanner a controversial component.
- LinkScanner Concerns – When AVG 8.0 was first released, its LinkScanner safe search feature was shown to cause an increase in traffic on websites that appear high in search engine results pages. Since LinkScanner disguises the scans as coming from an Internet Explorer 6 browser when it prescans each site listed in the search results, website usage logs showed incorrect and overinflated site visitor statistics. The prescanning of every link in the search results also caused websites to transfer more data than usual, resulting in higher bandwidth usage for website operators and slow performance for users. AVG initially said site administrators would be able to filter the LinkScanner traffic out of their site statistics, leaving the problem of excess bandwidth usage still to be solved. Pay-per-click advertising was not affected by the increase in traffic.
- AVG Online Shield – AVG Online Shield is a feature, designed to check files and ensure that they are safe. AVG Online Shield also ensures the safety of exchanging files via instant messengers and VoIP clients.In response to complaints, AVG announced that as of 9 July 2008 “Search-Shield will no longer scan each search result online for new exploits, which was causing the spikes that webmasters addressed with us”, releasing a new build on that date that applies a local blacklist, then prefetches and scans only those links clicked on by the user
