Last week i downloaded programs from (3) sources - I had a bad IOMagic DVD drive, and the tech support people had me run a patch (for ASPI.sys, I am pretty sure). Drive is definitely bad, so moving on (does not work on the netbook either), I tried to install a utility from Autocad. Much, Much trouble. And then, on top of things, a Microsoft update showed up.

Since that day, Firefox will no longer search from the toolbar. Crashes. Checking the crash log postings on their website, it appears that I am not the only one. If I type the name of the website in directly, it does not crash - well, it goes to intermittent.

Internet Explorer will run OK, but I have started getting "Your Computer is Infected" popups.

Of the three compters on the network, this is the only one doing it.

Scanned with AVG, nothing found.

Replaced AVG with Microsoft Security essentials - scanned again - only found my VPN software.

Virtual machine will no longer run.

Cute PDF will no longer print.

Reinstalled Firefox - no change.

I have a decent handle on what is in the HJT log from earlier rtroubles on other machines - most of the software that i install intentionally ends up on the ignore list. Some suspicious stuff that i leave in the normal scan just because i don't like them.

Also ran RootKitRevealer - mostly older "stuff' from years before, but 1 new one - HKLM\Software\Microsoft\Shared Tools\(5 characters that the screen cannot interpret - actually, the center one is an asterisk) from February 2010.


Following the instructions (thinking that I am infected), I get to the step where dds.scr is downloaded to the desktop, and when I click on it, it gets opened in notepad - a bunch of characters run together. Properties on the file say that it is a "DWG TrueView Script" File (wasn't this a reserved suffix in Windows?)

OS in Win XP, SP3.

Dual boot - Vista (never really worked out - Legacy programs are just too expensive to replace all at once) - IE works fine under Vista. Memory says that Firefox did, too, but I did not log everything at that point.

I'm not sure where to go from here...... So I thought I would ask.

Please download Malwarebytes Anti-Malware (v1.44) and save it to your desktop.Download Link 1
Download Link 2
MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Download this file and save it to your desktop:

http://download.bleepingcomputer.com/grinler/rkill.scr

Double-click the file to run it. A command window will open briefly. Then run another quick scan with Malwarebytes. Post the Malwarebytes log.

Actually, the MalwareBytes did more than I thought - i must have missed a "reboot" step somewhere. This morning's boot actually failed (with a "cannot access memory location" error - I should have taken a screenshot, but nothing was operating). ******Something****** said that the computer needed to reboot (Likely MalwareBytes). Started to shut down, and computer locked up. Let it sit for a half an hour before i killed the power.

The computer not only booted properly on the next attempt, but Firefox is OK again, CutePDF works again, and Virtual Machine starts OK.
Hijack This logs and Rootkit revealer have not changed.

The (Rkill and dds).scr files still seem to be registered as DWG trueview files - won't run, only open in notepad. SCR seems to be the extension for screen savers. This looks like either an error on AutoCad's part or damage from the virus.

If I were to speculate at this point, it seems that the Malwarebytes update cured it. I've got some cleanup and security tightening to do. Some confidence building, too.
I will get the file registration issue solved, but I don't feel that it is a malware infection issue (possibly caused by it, but not likely something that can be cured by anti-malware actions).

Is it still of any value to run the dds and rKill when I get this fixed?

just an update - seems like the AutoCAD .SCR issue is AutoCAD's - they hijacked the suffix for their own use. And since it is a system suffix, it needs to be changed in the registry as far as I can tell - no other way to associate a different suffix for screen saver files.

This is crossing in to another area - don't worry about it here.

Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.

Note that the last two are programs that I know about - not anything that needs to be removed.

The E:\OldFrankenstein is an archive from an old computer - programs haven't run for years - not yet on this computer - back from '98 days.

The d: Drive is the system drive - I have no clue what CPTEOVRLY.DLL is.

I must have cleaned the cookies - not many there, and mostly from when I run Vista.

Computer is running well - I haven't been able to get the .scr issue worked out yet, but like i said before, it is not the issue any more.
