Hi, I'm 90% sure I've got a trojan, and TDS3 does not detect it. The symptoms are: - the infected system started producing application (mainly Firefox and Java/Eclipse) and system (BSoD) crashes; - every attempt to reinstall (repair) the operating system on the infected drive resulted in a failure with complaints that some files cannot be copied (the files that really exist and are not corrupted); this "bad" file list was different for every new installation attempt; the result was the same whatever system (WinXP, Win2003) was installed/repaired and whatever distribution source was used. - an installation to a fresh HDD on the same system block completed without any problems; - the infected HDD operates as a secondary drive under the new operating system without any problems. I have a strong suspicion that I got a trojan that resides in the boot area and runs the normal bootstrapper in the VM mode. I have some time (not too much ) that I can spend on investigation of this phenomena before I have to reformat the infected drive (or try to repair the MBR), but I'll need guidance and instructions. Anybody willing to participate?
