Your post would be more on topic. And it's where all the security mavens are.
I just wanted to let you know that the avasti 4.6 which is free is really user friendly and not only that it works. It is great for trojans, I had one on my computer and spent a day scanning for it with no luck; then went on to download and looked for new software. Avasti came up, I tried it and it found the trojan right away. The software xoftspy 410s also found it but you needed to buy in order to remove the virus, and avasti is free. I have the following on my computer and while AVG and adaware are good they could not help me with this worm. AVG free, AdawareSE, Spybot S&D, Spyware Blaster, Norton Antivirus. Further I tried Stinger 2.4.7 but it didn't work either, so removed it. Avasti is the one for you if you have a worm.
