writes "The Register is running a story about a new feature in the AVG virus scanner.
Six months ago, AVG acquired Exploit Prevention Labs and its Linkscanner, a tool that automatically scans search engine results before you click on them. If you search Google, for instance, and ten results turn up, it visits all ten links to ensure they're malware free.
Then, in late April, AVG rolled Linkscanner into its anti-virus engine, which has about 70 million active users worldwide. The company estimates that 20 million machines have upgraded to the tool's new incarnation, AVG version 8, and this has already cooked up enough ghost clicks to skew traffic not only on The Reg but any number of other sites as well. What will the effect be when AVG rolls this new fewture out to all of its 70 million users?"
