I've seen this one mentioned on other threads here... perhaps one of you guys can HELPPPPPPPPPPPP MEEEEEEEEEEE.... -- I've got some hijack that A) Makes sure I have an IE shortcut to "Casino Palazzo" on my desktop -- and B) Causes a world of other problems... I'm getting error messages that I've never seen before and occasional IE crashes, and I'm getting virus alerts from symantec detecting the downloader trojan (and other trojans) I'm getting pop ups from windows file protection telling me I "must install" spyware blocking software now -- click here -- (<----- that's a spoof isn't it... it sure looks spoofy).

I've got adaware and spybot S&D and X cleaner all working and they all have found and cleaned stuff... but I'm still getting weird errors and I'm still getting occasionally redirected to a bogus search page... oh did I mention the kiddie porn pop-ups? This is some really evil sh-t.

Norton 2003 AV doens't seem to recognize the problem at all (although it has recognized some viruses that have tried to hop aboard my compromised immune system).

Is taskngr.exe a real program?

So. Now what do I do? I've downloaded Hijack this and it doesn't seem to want to run... I'm working on that problem now.

Thanks in advance.

Doug

Doug,

Delete taskngr ang telnetxp (in win sys 32). My Norton actually zapped taskngr.
Is your AV up to date?

Download and run CWShredder too.

Cheers,

Bigbuck.

Thanks Buck, I'll try those fixes.

My nav is 2003 and is up to date... sort of... I tried to use Symantec support--for-hire (at 70bucks a phone-call-fix, but I was desperate, err, still am desperate) and they wouldn't even take my money! They said 2003 and just didn't recognize adware at all and I should get NAV2004... on top of that, get this, the tech said that Norton didn't want to get involved with adware because it's LEGAL and they could be sued... I can understand that some stuff is legal (if hateful) but the tech really peeved me because this thing on my machine is dl'ing absolutely vile porn (and I ain't that easy to shock either) and calling out to every virus on the net "party at Doug's house," it's rewriting files and just making my life hell... there's just no way it's legal. No way... a BS answer if I ever heard one...

I really hope your fixes work. By the way, I can't get Hijack This to run on my machine, in fact I managed to get one copy dl'd, but now I've tried to dl another and I can't get it to download. I suspect the virus is to blame... paranoid?

Do you, or anyone, know what I can do about this?

Doug.

Doug,

I'm pretty much in the dark too, but I did have the casino icon on my desktop (no porn thank god).
& telnetxp & taskngr in the win sys 32 files. I just kept deleting telnetxp and it came back. CWShredder got rid of it I think. It might keep coming back because of system restore? if you're on Me or Xp you might have to turn system restore off because the infection might be in a restore file??
My old Norton 2003 zapped taskngr from my backup harddrive after I had deleted it from C:. Norton called it a Downloader Trojan.

Copied this stuff from symantec response centre for you.

Your Norton is the same as mine, it should get this one.

Cheers and Good Luck,

Buck

Various worms and backdoor Trojans use Downloader.Trojan to spread themselves over the Internet. Thus, Downloader.Trojan accesses and downloads from various sites.

Some of these Web sites and downloaded Trojans are:
Web site: www.alibabanet.net
Trojan: Backdoor.IRC.Aladinz

Web site: www.starsea.as.ro
Trojan: IRC.Momma.Worm

Web site: www.kamerali.com
Trojan: W32.Ronoper.Worm







Symantec Security Response encourages all users and administrators to adhere to the following basic security "best practices":

Turn off and remove unneeded services. By default, many operating systems install auxiliary services that are not critical, such as an FTP server, telnet, and a Web server. These services are avenues of attack. If they are removed, blended threats have less avenues of attack and you have fewer services to maintain through patch updates.
If a blended threat exploits one or more network services, disable, or block access to, those services until a patch is applied.
Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services.
Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
Configure your email server to block or remove email that contains file attachments that are commonly used to spread viruses, such as .vbs, .bat, .exe, .pif and .scr files.
Isolate infected computers quickly to prevent further compromising your organization. Perform a forensic analysis and restore the computers using trusted media.
Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.


The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.


Disable System Restore (Windows Me/XP).
Update the virus definitions.
Restart the computer in Safe mode or VGA mode.
Run a full system scan and delete all the files detected as Downloader.Trojan.
Edit the registry and look for references to the Trojan.

For specific details on each of these steps, read the following instructions.

1. Disabling System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.

For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles:
"How to disable or enable Windows Me System Restore"
"How to turn off or turn on Windows XP System Restore"

For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article, "Antivirus Tools Cannot Clean Infected Files in the _Restore Folder," Article ID: Q263455.

2. Updating the virus definitions
Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions:
Running LiveUpdate, which is the easiest way to obtain virus definitions: These virus definitions are posted to the LiveUpdate servers once each week (usually on Wednesdays), unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, refer to the Virus Definitions (LiveUpdate).
Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted on U.S. business days (Monday through Friday). You should download the definitions from the Symantec Security Response Web site and manually install them. To determine whether definitions for this threat are available by the Intelligent Updater, refer to the Virus Definitions (Intelligent Updater).

The Intelligent Updater virus definitions are available: Read "How to update virus definition files using the Intelligent Updater" for detailed instructions.

3. Restarting the computer in Safe mode or VGA mode
Shut down the computer and turn off the power. Wait for at least 30 seconds, and then restart the computer in Safe mode or VGA mode.
For Windows 95, 98, Me, 2000, or XP users, restart the computer in Safe mode. For instructions, refer to the document, "How to start the computer in Safe Mode."
For Windows NT 4 users, restart the computer in VGA mode.


4. Scanning for and deleting the infected files
Start your Symantec antivirus program and make sure that it is configured to scan all the files.
For Norton AntiVirus consumer products: Read the document, "How to configure Norton AntiVirus to scan all files."
For Symantec AntiVirus Enterprise products: Read the document, "How to verify that a Symantec Corporate antivirus product is set to scan all files."
Run a full system scan.
If any files are detected as infected with Downloader.Trojan, write down the path and file names, and then click Delete.

5. Editing the registry


--------------------------------------------------------------------------------
WARNING: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified keys only. Read the document, "How to make a backup of the Windows registry," for instructions.
--------------------------------------------------------------------------------

Click Start, and then click Run. (The Run dialog box appears.)
Type regedit

Then click OK. (The Registry Editor opens.)


Navigate to each of these keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run


For each one, in the right pane, delete any values that refer to any files that were detected as Downloader.Trojan.


Exit the Registry Editor.

Thanks Buck,

I'm going to try the NAV solutions -- (especially as I can't seem to get hijack this or cwshredder to work) the problem is definitely that deleted infected files keep coming back. I am definitely getting deleted files returning to life, almost certainly because of Windows File Protection. I deleted the files you suggested but the hijacking continues unabated, in fact worse than ever.

I've get downloader trojan alerts from NAV regularly... but my machine is trying to download the downloader trojan and NAV is blocking it, I believe. I think the infection is something else... but it won't hurt to try the process you reccommended anyway.

Wish me luck,

Doug.

The thread in http://www.computerc...ostp226121.html discusses the same problem.

In particular, read the responses by jbrown7711 and brkerez -- one of them should be relevant to your situation.

Hope this helps.

Thanks Gasp. That did help. Both jbrown and brkerez's posts were pertinent to me. I had resolved _most_ of my probs, but those guys helped me get rid of the stragglers.

By the way... my main solution was simply to get rid of my vulnerable MS apps (but I haven't gotten rid of XP yet) and go open source.

Along with the spyware issues I was having trouble with some infection of MS word that had completely polluted the normal.dot file -- after reading online about other folks struggles with MS word and the normal.dot file... I threw in the towel and said -- I'll bet there's an open source software outthere that isn't getting massacred by viruses and spyware.

A few days later and so far (fingers crossed) I'm very happy with firefox browser, thunderbird mail, and abiword word processor. They use less resources and appear less vulnerable to attack.

Okay, IMHO it's the absolute WRONG reason to let the spyware and virus writers push me around, but, well, in this case: the terrorists won. :-(

I guess the moral of the story though, is that like so many millions of others users out there, I don't have any loyalty to Microsoft and takes very little to get me to switch. I guess I wish I'd had the sense to switch _before_ I got all infected.

Thanks for the help.

Doug.
