AVG Driver Updater
AVG PC Driver Updater is an application designed to scan and easily update outdated device drivers on Windows computers.
AVG PC TuneUp
AVG PC TuneUp is an application designed to speed up the computer by removing files that may slow down the operating system and optimizing some of its settings. If a user does not purchase this product when purchasing the anti-virus product, then AVG will intermittently display popup ads to entice one to purchase the product.
AVG features most of the common functions available in modern anti-virus and Internet security programs, including periodic scans, scans of sent and received emails (including adding footers to the emails indicating this), the ability to "repair" some virus-infected files, and a quarantine area ("virus vault") in which infected files are held.
AVG Online Shield
AVG Online Shield is a feature, designed to check files and ensure that they are safe. Only then it downloads them on your computer. AVG Online Shield also ensures your safety while you exchange files via instant messenger and VoIP clients like MSN and Yahoo! and ICQ.
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.
When AVG 8.0 was first released, its LinkScanner safe search feature was shown to cause an increase in traffic on web sites 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, web site usage logs showed incorrect and overinflated site visitor statistics. The prescanning of every link in search results also caused web sites to transfer more data than usual, resulting in higher bandwidth usage for web site 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.
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 web site in real-time to ensure it's safe being opened. Concerns regarding web analytics have made LinkScanner a controversial component (see below "LinkScanner Concerns").
