I just tried this utility after about one year and tried it against some spyware/ adware downloads. I just enabled the worm intrudor blocker and security watch dog function of it and tried to download following spywares/ malwares: WinFixer UnSpyPC Jessica Simpson Screensaver( so called) Kazaa Mediapipe SpyAxe Waterfalls 3 And surprizingly it blocked the download attempts of all except one of these malwares( except JS screensaver). That,s great. I am really impressed. I have not seen any free/ paid software that is so good in this regard. I tried same with SpySweeper and it blocked only three of them ( WinFixer, SpyAxe, Mediaptpe)- blocking access to the download. It functions as web communication shield, so it blocks possible malware download, however if the malware is already downloaded on ur PC, it will not prevent its execurtion. I executed few of above spyware installers, and it remained dead silent. But its web shield function is really great, and I think it can eb a nice add-on to a real time Antispyware scanner. It has a Worm Hunter( and many other things) as well but can,t say how good it is. Currently i am using it and activated following components, Security watch dog Intrudor blocker Banner blocker Movie Blocker Privacy Protector Its, GUI is not good but if it works well that should not be any problem, especially that it is free. Here is a pop up that it gave during my testing.
