I have windows XP Pro, I ran a scan on my hard drive using Windows Defender, at the end of the scan it said i had been infected by a Downloader Trojan and that I should remove it immediately, I did this Straight away thinking that my problem was gone. Then when I ran the Scan again the next day, it said I had the same problem with this Downloader Trojan. Everytime I removed it and ran the Scan again later, it kept coming back. Can someone tell me how I can manually get rid of it for good ? Johnoflynn33@gmail.com

Download AdAware Personal from lavasoftusa.com and try that one. Might have better luck than Defender.
