Hi All, First post here,and I wanted to ask "At what stage do you stop testing"? I have just cleaned a winxp pc of various spyware threats. First was update and run Macafee virus. 0 found. Then same with AdawareSE. 27 malicious threats plus 3 that needed reboot to fix. Then run Ewido.3 found and removed. Ditto MS antispyware. Finally ran Spybot which found 94! still there including various search/shopping trash. So, when is enough enough! And why are so many threats not found when you update to the latest definitions of various programmes? Just what is the final assurance that your PC is clean? A re-format? Ewido was disappointing,considering it's reviews. I have it on my machine,but S&D picked up so much that got through My PC is totally clean,but I have about 8 different test tools and don't surf porn,warez,file sharing etc The problem comes when new users click for free stuff etc and get infested. Minutes to get in,hours to get out. That's if you KNOW you have it all.
