Hi everyone - I have been an avid reader of the forums here and have found many useful tips to remove malware and the like, but I have hit a bump in the road with my own infection!

To give a brief background, I believe I was infected with malware about 2 weeks ago through one of those fake anti-virus pop ups. At the time, the damage it was causing was browser redirects, unexpected /intermittent shut-down of all open programs, desktop icons and shortcuts would jump back to their original positions after dragging them to other positions, and inability to send/receive emails through Outlook (not my choice to use Outlook or Internet Explorer.. but that's another story!). I ran Malwarebytes and it cleared about 13 infections. I also ran AVG and it picked up a few issues which I quarantined. All seemed OK at this stage, the browser redirects were gone and emails were back. The desktop icons still 'jumped back' to their original positions but I thought I could live with this. Unfortunately I still can't work out where I picked up the Malware. I do a fair bit on internet browsing but nothing that I thought was too suss.

Fast forward a week or two and my system was running OK, albeit a bit slow. Then one night the computer closed all programs and restarted. On logging back in, I got a message which stated that windows had 'recovered from a serious error' - similar to what this user was experiencing http://www.geekstogo...r-virus-solved/ After this point I thought it was too risky to keep trying to fix the problem myself and have turned to the forums to try to help! Since the original infections, I've run both Malwarebytes and AVG multiple times and every time they come up clean, which confuses me as some of the symptoms are still there.

Thanks in advance to anyone that can help, I really appreciate it and could use a helping hand/guide as I have been winging it so far (I know I know, should have asked for help first but thought I could handle it!) ~ cicalany

I've followed the Guides and have posted the relevant logs below:

Thanks so much for your speedy response Ron.

I'm sorry I should have mentioned this earlier - I run through a remote desktop connection as well sometimes and anything referring to rjs or rjshot is the remote desktop connection/hotspot. I would just like to confirm whether running any of the above in your reply will damage the remote connections.

Apologies again that I forgot to mention it. Otherwise I am all ready to try your suggestions

Copy the text between the lines of stars by highlighting and Ctrl + c.

******************************************

AtJob::

DirLook::
C:\Program Files\Common
%user%\library

Driver::
zxsivdrnq
SAVRKBootTasks

NetSvcs::
zxsivdrnq

******************************************

Now open notepad (Start, Run, notepad, OK) and Ctrl + V to paste the text into Notepad. Make sure you got it all then File, SAVE AS, (to your Desktop), CFScript , OK. Close notepad. (Overwrite the old one if it's still there.) You should see a file CFScript.txt on your desktop.

Pause your anti-virus.

Drag CFScript.txt over to Combofix and let go Combofix should start on its own.

Post the new log.

We need to clean up System Restore.

Copy the following:


:Commands
[CLEARALLRESTOREPOINTS]
[Reboot]

Run OTL. In the Custom Scans/Fixes box at the bottom, paste in the copied text (Ctrl + v) and then hit Run Fix.

That will remove what I hope is the last of the malware. Are you seeing any problems?

If you really want to be sure you can run an ESET scan. Takes hours but is very thorough.
Use IE and go to http://eset.com/onlinescan and click on ESET online Scanner. Accept the terms then press Start (If you get a warning from your browser tell it you want to run it).

# Check Scan Archives
# Push the Start button.
# ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
# When the scan completes, push LIST OF THREATS FOUND
# Push EXPORT TO TEXT FILE , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
# Push the BACK button.
# Push Finish
# Once the scan is completed, you may close the window.
# Use Notepad to open the logfile located at C:\Program Files\EsetOnlineScanner\log.txt
# Copy and paste that log as a reply.

Note that files it finds in subfolders of C:\qoobox and C:\_otl\ have already been rendered harmless by Combofix or OTL.

Let's also try the bitdefender quickscan.

http://quickscan.bitdefender.com/

When it finishes there is a View Report option at the bottom. Click on it and copy and paste the report (even if it says nothing found).

Hi Ron - everything is running smoothly and I can't see any evidence of the previous symptoms I had, yay! I'm keen to make sure it is as clean as possible though, so I have performed the additional steps:

I can't really tell if ESET removed the thing it found. Let's make sure with OTL:

Copy the text in the code box by highlighting and Ctrl + c


:OTL
[2012/05/25 15:39:32 | 000,000,000 | ---D | M] (Mozilla Safe Browsing) -- C:\DOCUMENTS AND SETTINGS\KATHRYN\LOCAL SETTINGS\APPLICATION DATA\{B1DB09DF-A62B-11E1-8270-B8AC6F996F26}

then Rightclick on OTL and select Run As Administrator to start. Under the Custom Scans/Fixes box at the bottom, paste (ctrl +v) the text. Verify that you got it all and make sure all browsers are closed Then click the RUN FIX button (NOT THE QUICK SCAN button!) at the top
Let the program run unhindered, OTL will not need to reboot. If you see the log please save it then copy and paste it.

That should be all so we can now cleanup.

We need to cleanup System Restore:

Copy the following:


:Commands
[CLEARALLRESTOREPOINTS]
[Reboot]

Right click on OTL and Run As Administrator. In the Custom Scans/Fixes box at the bottom, paste in the copied text (Ctrl + v) and then hit Run Fix.

That will get the last of the malware off the system.

You can uninstall or delete any tools we had you download and their logs.
To uninstall combofix, copy the next line:

"%userprofile%\Desktop\combofix.exe" /Uninstall

Start, All Programs, Accessories then right click on Command Prompt and Run As Administrator.
then right click, Paste, then hit Enter.

OTL has a cleanup tab if you go there it will remove itself and its logs.

To hide hidden files again (OTL may do it for you):

Vista or Win7

# Open the Control Panel menu and click Folder Options.
# After the new window appears select the View tab.
# Remove the check in the checkbox labeled Display the contents of system folders.
# Under the Hidden files and folders section select the radio button labeled Do not Show hidden files and folders.
# Check the checkbox labeled Hide protected operating system files.
# Press the Apply button and then the OK button and exit My Computer.

Also make sure you have the latest versions of any adobe.com products you use like Shockwave, Flash or Acrobat.

Whether you use adobe reader, acrobat or fox-it to read pdf files you need to disable Javascript in the program. There is an exploit out there now that can use it to get on your PC. For Adobe Reader: Start, All Programs, Adobe Reader, Edit, Preferences, Click on Javascript in the left column and uncheck Enable Acrobat Javascript. OK Close program. It's the same for Foxit reader except you uncheck Enable Javascript Actions.

To help keep your programs up-to-date you should download and run the UpdateChecker:
http://www.filehippo.../updatechecker/
(You don't need to download Betas and if there is a program you don't use you can just uninstall it rather than update it. Exception is MSN messenger which appears to be part of Windows.)
If you get a blocked program notice after installing updatechecker then change it to not run at start then manually run it once a week.
Seems to work best if Firefox is the default browser. You can also try Secunia PSI http://secunia.com/v...l/download_psi/ Same kind of info. You don't need both.
If you use Firefox then get the AdBlock Plus Add-on. WOT (Web of Trust) is another you might want to try.
The equivalent to AdBlock Plus for IE is called Simple Adblock and you should install it too: http://simple-adblock.com/
The free version only blocks 200 ads a day so another reason to use Firefox or Chrome.

If Firefox is slow loading make sure it only has the current Java add-on. Then download and run Speedy Fox.
http://www.crystalidea.com/speedyfox . You can run it any time that Firefox seems slow.

Be warned: If you use Limewire, utorrent or any of the other P2P programs you will almost certain be coming back to the Malware Removal forum. If you must use P2P then submit any files you get to http://virustotal.com before you open them.

If you have a router, log on to it today and change the default password! If using a Wireless router you really should be using encryption on the link. Use the strongest (newest) encryption method that your router and PC wireless adapter support especially if you own a business. See http://www.king5.com...-120637284.html and http://www.seattlepi...ted-1344185.php for why encryption is important. If you don't know how, visit the router maker's website. They all have detailed step by step instructions or a wizard you can download.

Sorry, I gave you the cleanup routine for Vista/Win 7.

To uninstall combofix, copy the next line:

"%userprofile%\Desktop\combofix.exe" /Uninstall

Start, Run, cmd, OK then right click, Paste, then hit Enter.

OTL has a cleanup tab so if you run it again and select cleanup it will remove itself and its backup files.

To hide hidden files again (If you do not run OTL cleanup):

XP

# Close all programs so that you are at your desktop.
# Double-click on the My Computer icon.
# Select the Tools menu and click Folder Options.
# After the new window appears select the View tab.
# Uncheck the checkbox labeled Display the contents of system folders.
# Under the Hidden files and folders section select the 'Hide protected operating system files (recommended)' option.
# Check the checkbox labeled Hide protected operating system files.
# Press the Apply button and then the OK button and exit My Computer.

Also make sure you have the latest versions of any adobe.com products you use like Shockwave, Flash or Acrobat.

(You don't need to download Betas and if there is a program you don't use you can just uninstall it rather than update it. You can right click on the updatechecker icon (looks like a downward green arrowhead) and select Settings and tell it no betas. If you don't use MSN Messenger I would not upgdate it. MS installs a bunch of stuff when you do. You can tell the program to not show you that update.)
If you use Firefox or Chome then get the AdBlock Plus Add-on. WOT (Web of Trust) is another you might want to try.
The equivalent to AdBlock Plus for IE is called Simple Adblock and you should install it too: Adhttp://simple-adblock.com/

If Firefox is slow loading make sure it only has the current Java add-on. Then download and run Speedy Fox.
http://www.crystalidea.com/speedyfox . Click on Speedup my Firefox. When it finishes click on Exit.

No we still want to do that just to make sure it is gone. ESET may have removed it.

Copy the text in the code box by highlighting and Ctrl + c

:OTL
[2012/05/25 15:39:32 | 000,000,000 | ---D | M] (Mozilla Safe Browsing) -- C:\DOCUMENTS AND SETTINGS\KATHRYN\LOCAL SETTINGS\APPLICATION DATA\{B1DB09DF-A62B-11E1-8270-B8AC6F996F26}

then run OTL and Under the Custom Scans/Fixes box at the bottom, paste (ctrl +v) the text. Verify that you got it all and close all browsers then click the Run Fix button at the top
Let the program run unhindered, OTL will reboot the PC when it is done. Save the log and copy and paste it to a reply.

After that then we can do the clean up.
