I had a client get hit by a drive by "fake infection" trojan. Eset didn't detect anything either (v 220.127.116.11) and after I managed to get it cleaned off through a few scans of Malwarebytes, TdssKIller, and some tweaking via hijackthis, all seemed to be working again. I tried to load up Eset and noticed that half the modules were not loaded and nothing I did would get them to load correctly. I figured I'd reinstall, so I uninstalled, rebooted, and downloaded v5. Tried using the Live Installer and the Offline installer. Both failed stating that a reboot had not been completed since a previous uninstall. Even after multiple reboots. Retried using v4 again. Same issue. I followed the instructions for manually uninstalling and even used the Eset uninstaller, all of which completed successfully. But anytime I try to install NOD, it fails every time. Nothing else fails. I've updated Adobe reader, flash, java, spywareblaster, malwarebytes, etc... with success every time. Running Windows 7 64-Bit SP1. Thoughts?
