My Windows XP 64 bit system was recently attacked by a sys32 Trojan virus. I launched Norton 360 with Threat Removal Layer and Safe Web but came up with nothing. I installed Avast Antivirus and scanned my PC and that's where I detected the Trojan. Why did Symantec Norton 360 not detecting this?
Norton 360 did not detect trojan virus
I have experienced this problem. Listen, you have to re-install your Windows. But before that, you need to ready a powerful antivirus like Norton Internet Security 360 or Kaspersky Lab.
After installing Windows, you have to install that internet security system and update as well. You have to do a full scan of your PC.
I think this will solve your problem.
