Hello,

Background:
I run a router with firewall, hostbased firewall(zonealarm) and a virus checker(symantec) with auto updates daily. I'm on windowsXP pro version 2002 SP3 with auto update set to download and prompt me for install. I usually install patches as long as they apply. Most recently something set it to full auto as I haven't been prompted for new patches but I set it back as before.

First sign of infection was during browsing the mallware tried to install antivirus2009. I knew about the antivirus2009 issue and tried to cancel right away. Side note: is there a way to post screen captures of errors? I saved most windows in word document and posting caps would make my post more accurate and save a lot of typing. The firt window was a windows run/save/cancel prompt titled File Download - "Security Warning". File name: InstallAVg_770522170802.exe type: Application, 160KB From: bestantivirusscanner.com. I did not initiate this so I know right away something was up. Hitting cancel closed the window but started the install. Then a full screen window of antivirus 2009 opend with a small window titled Microsoft Security Warning. The heading was "Antivirus 2009 Web Scanner detected dangerous spyware on your system!" with more verbge strongly recommending I remove malicious programs it "detected". The list showed Spywre.IEMonster.b, Zlob.PornAdvertiser.Xplisit, and Trojan.InfoStealer.Banker.s. with risk level Critical/high/medium respectively. At the same time zonealarm poped up a prompt "suspicious behaviour": LVCom Server is trying to set 'CPMd3cd69ef' to run each time your compter is started. I managed to close the antivirus2009 installer and clicked deny on the zonealarm prompt. I also got two more windows one titled Windows Internet Explorer: "Dont close this window if your want you PC to be unsoiled". I don't use IE. The other one was titled Windwos Internet Explorer:"Destructive and damaging software founded. It can casue harm to your machine and corrupt your peronal information.Online Security Scanner demands Anitvirus 2009 elements to fix your computer. Please click Ok to download and install Antivirus 2009 components. Yet another also titled Windows IE:"Internet Explorer cannot download 85qcs1exx.dll.html from 77.74.48.105.
Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later."

At this point symantec identified trojan.Vundo which it was able to clean. Just to be sure I downloaded their removal tool and it didn't find it suggesting it was removed ok. Since then zonalarm has been going off every time I start a program with the warning: "QuickCam Framework Server is attempting to monitor user activities on this computer. If allowed it may try to track or log keystrokes (user input), mouse movements/clicks, web sites visited, and other user behaviours. Application:FxSvr2.exe. No smart adviser info was available. I clicked deny to all of them.

The antivirus2009 install would periodically try to reinstall again. It looks like the malware reloads itself despite symantec having cleaned it. Symantec would detect it again and clean.

Now I don't get the install anymore but periodically IE starts up and opens multipe tabs and tries but fails to open pages then a new IE window opens and repeats the process. Unfortunately I didn't make a note of the IPs it was trying to load. This seems to be a timed launch as it hasn't happened for a a day or two.

What I have done: Aside from cleaning the infections I tried to follow the guide on this site and ran autoruns in hopes of finding the malware but no cake yet. I posted in the startup forum about a couple of suspicious entries I found:

http://www.bleepingcomputer.com/forums/t/198065/help-identify-startup-programs-on-infected-machine/

I tried installing spybot and adaware but I get a an error whenever I try installing something: "unable to execute file in the temporary directory. Setup aborted. Error 5: Access is denied.

I checked permissions on the \temp and it looks fine.

Please help!

is there a way to post screen captures of errors?

Hit the Print Screen key, then open Paint. Click on Edit and select Paste
As I said in your other thread, if it doesn't show in a Google search. it's not a good sign
-----------------------------------

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

---------------------------------

If mbam won't install

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

When I download mbam I get the "unable to execute file in the temporary directory. Setup aborted. Error 5: Access denied." error. Tried renaming it, same outcome. I'll try it from safe mode see if it helps....

P.S. I'm familiar with how to capture the errors but when try to paste it into the posting box it doesn't work. Tried saving it in paint as a jpg and dropping it in the dialog but the browser opens it to display it. Hmm. I'm using opera, not sure if it has somethig to do with it. I'll try firefox too.

Things are getting interesting...when I rebooted to go into safe mode there was no recovery console. pressed F8 and the only option was to load winxp. Aslo, during shutdown a number of programs were running that needed to be ended. One name I noticed was weird but I couldn't write it down in time. It was something like _acroS_Win. Not sure if I got the case/underscores right. It deffinitely started with the "_". Also, during shutdown, I got the IE message saying unable to download 8jnOq4.dll. No hits on it in google. The O could have been a 0.

I have to see if I can install the recovery console. I will google for instructions but any pointers would be welcome as I never had to do this before. It was always there.

EDIT: Sorry wrong terminology. Googled recovery console and that's not what I want. I want to add safe mode to the available OS list when I press F8. Is there any point to running the windows install CD to do repair?

You can neither install or remove Safemode. It is not an application, it is a integrated part of the operating system

Is there any point to running the windows install CD to do repair?

Right now that sounds like your only option
