Need Help Removing Spyware.Netrat and Trojan Horse

by tonyzeng / March 15, 2008 7:29 AM PDT

My computer is affected with Spyware.Netrat and TrojanDownloader:Win32/Harnig.gen!L (trojan Horse) but my antivirus can't remove it. I use the Norton AntiVirus 2008 with Antispyware and I have Window XP. Both of the Spyware and Trojan are from a compressed file. I try to manually deleted it but i didn't find the file stated in the manual (http://www.symantec.com/security_response/writeup.jsp?docid=2003-080811-2822-99&tabid=3
http://www.symantec.com/security_response/writeup.jsp?docid=2004-021914-2822-99&tabid=3) Can you please help me out on how to remove it because the computer has been affected over a month and i don't know if any of my information was taken by a third-party? Thanks in advanced.

you posted the links to the removal advisories, you attempted to follow them but couldn't.
When your AV flags this/these, what are the detected names/paths? That would be a place to start looking.
You will need to display hidden files, which you can do via "tools>folder options" in any explorer window.
http://www.superantispyware.com/ has a good reputation for helping to remove this sort of nasty, give it a whirl.

Hi Tony,

This is Mike from the Norton authorized Support team responding to your post regarding infections on your computer. Norton AntiVirus 2008 does have the ability to detect and remove threats in compressed files. The first thing I would recommend is that you manually run LiveUpdate from the main Norton AntiVirus window. Run LiveUpdate manually as many times as needed until you are informed that no more updates are available.

After you update your installation, please reboot into Windows Safe Mode and then run a Full System scan from there.

Please let me know if you are successful after updating and running the scan in Safe Mode.

Thank you,

Did you complete the steps in the Symantec document?

Hi Tony,

I'm sorry to hear that you are still having problems removing the threats on your computer.

In your posting, you give the links on the Symantec support site which describe the instructions for manually removing these threats. Can you please let me know if you followed the instructions on the 'Removal" tab in these two documents? This would include, for example, turning off System Restore and also backing up your Windows registry and manually deleting the entries. Please let me know if you have followed all of the steps in the "Removal" tab, located in both of the documents that you referenced.

You may also want to try using the Symantec Online Security Scan, which must be run using Internet Explorer 5.5 or higher.

Please make sure that all applications are closed and then click on the following link and run both of the tests.


Thank you,

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
