I scanned my computer with Norton Anti Virus before i knew about TDS, it found 3 trojans, but were unable to delete them from my computer. When i scanned my computer with TDS it only found one of the 3 listed by Norton, but it also found 2 different kinds that Norton never detected. TDS got rid of the trojans no problem, but the trojans still remaining on my computer are still causing trouble. My problem is, is that i dont know where to scan my computer in order to find those hidden trojans. Norton says that the trojans are located in C:\system volume information\_restore. Help would be greatly appreciated. Thanks. By the way TDS is great, i have been looking all over the internet and couldnt find a single program that could even detect the trojans that i had.
