I am using Windows Vista operating system with McAfee antivirus and my browser is Opera 10. The infection called Trojan.DL.Win32.Undef.egy keeps entering my system whenever I am surfing the internet. I remove it everytime when the antivirus alerts me about its entry, but again I keep getting its alerts. I dont understand why this is happening. So, I need to know how to delete Trojan.DL.Win32.Undef.egy. Anyone having information on this problem is expected to reply.
