Linkscanner works better than blacklists!
First off, I've recently switched over to using and recommending AVG 8 as the Linkscanner technology and low resource utilisation make it stand out from the crowd.
AVG's Linkscanner works a treat and is a better solution than blacklisting. It does realtime inspection, looking for known exploits and other nasties. Blacklisting relies on someone or some systems detecting a nasty and reporting it so the website can be added to the blacklist. There is usually a delay in blackilisting whereas Linkscanner protects in real time.
No other AV / security suite that I know about has the same level of protection as Linkscanner! Most AVs rely on blacklisting or watching out for the infection to be downloaded onto your system before reacting. Linkscanner uses many other techniques to ensure the malware stays on the server in most cases!
The realtime inspection feature of Linkscanner isn't included in the free version of AVG AV. You only get the search result inspection. Previous versions of AVG also restricted some features to be in the paid for version. AVG is, after all, a commercial company that needs to sell products to stay in business. The fact they provide a free edition with good and solid free protection is a great service to those who either can't afford or are too cheap to buy a license.
The new AVG 8 is VERY light on the host computer.
Users can do a custom install or switch off Linkscanner within AVG.
Agreed, it may not be for everyone, but anyone with even a half decent broadband connection shouldn't notice any difference when browsing the web. However, dial-up and big boy broadband users that provide poor service to their customers may well find it causes a lag in loading webpages.
Here's an example of where Linkscanner worked where other security solutions failed:
It even made The Register at the time:
It appears that nearly every day there is a story of another big website, that should be trustworthy, being hacked to serve malware. Technologies such as Linkscanner will provide the real time security that is needed to protect web users.
Bandwidth is cheap these days anyway. If smaller websites can't afford to pay for it then maybe they need to find alternate suppliers or reconsider their web presence.
As for webstats, most of the time they are a flaky indication for most businesses! Much better to measure the real business impact of your web presence i.e. visitors that convert to sales, number of user registrations, etc.
Keep up the good work Roger and AVG. Some of us appreciate your fabulous technology and what it can do to protect the end users from the ever increasing threats on the Internet.
