AVG released a new version of their flag-ship security products and will discontinue the current 7.5 version by end of May 2008. Starting next month, computer that still has 7.5 version installed will not get updated anymore including the virus definition. So it's vital to get this one upgraded. Fortunately, AVG still offers the free edition for private use only, though it isn't that obvious to find out on its website. Here is the shortcut.

One nice feature in this new version is LinkScanner that scans all links on search engine results page and indicates which links are good and which are dangerous. A very nice way to protect your computer. It works with all major search engine providers on both IE and Firefox.
And yes, of course, this feature eats your bandwidth quite a bit. So to disable if you want to, you can simply check off the option "Enable AVG Search-Shield" on Advanced AVG Settings under LinkScanner tab.
