Yesterday afternoon, windows defender popped up warning me of a virus: trojan.downloader Win32/Renos.dz. This was surprising because I have AVG 8.5 free which did not catch this virus and I have never gotten any messages from Windows defender. I clicked "remove" and thought everything was ok... Maybe 30 minutes later I get the same message. Again, I clicked "remove" and decided to do a full scan with AVG. AVG did not find any threats. I thought maybe I would install Malwarebytes anti-malware, but when I went to the website I encountered an error saying the server could not be contacted. I next tried to download Superantispyware... I got to the website fine, but when I tried to download it I got the same error saying the server could not be contacted. Using another computer I downloaded Malwarebytes anti-malware and installed it but it would not run. I renamed the program and it ran, but it froze while it was scanning a certain file. Later on that evening AVG started its scheduled scan and found and healed 4 threats. My computer has a second partition on which I've installed the Windows 7 release candidate. Today I installed Malwarebytes anti-malware on windows 7 and did a complete scan of my infected vista partition. It found and healed 3 infections. I thought that finally the problem was solved. I started up my Vista partition and what do you know, I get that same old windows defender message about that same virus. I can't get rid of it! Can anyone help me?

Can you post your malwarebyte scan log. -------------------------------------------------

Here is the malwarebytes log (I was mistaken when I said it found 3 infections... it only found 1): ------------------------------- Malwarebytes' Anti-Malware 1.37 Database version: 2192 Windows 6.1.7100 5/29/2009 3:04:01 PM mbam-log-2009-05-29 (15-04-01).txt Scan type: Full Scan (E:\|) Objects scanned: 335771 Time elapsed: 2 hour(s), 9 minute(s), 7 second(s) Memory Processes Infected: 0 Memory Modules Infected: 0 Registry Keys Infected: 0 Registry Values Infected: 0 Registry Data Items Infected: 0 Folders Infected: 0 Files Infected: 1 Memory Processes Infected: (No malicious items detected) Memory Modules Infected: (No malicious items detected) Registry Keys Infected: (No malicious items detected) Registry Values Infected: (No malicious items detected) Registry Data Items Infected: (No malicious items detected) Folders Infected: (No malicious items detected) Files Infected: e:\Users\sensenigsm1\AppData\Local\Temp\tmp3B58.tmp (Trojan.Downloader) -> Quarantined and deleted successfully.

Can you please post your AVZ log: Note: Run AVZ in windows normal mode. If avz.exe doesn't start, then try to rename the file avz.exe to something else and try to run it again. 1) To create the logfile, download AVZ by clicking HERE. Please save this file to your desktop or "My Documents" folder. 2) Next, unpack the file to a new folder using the Compressed (zipped) folders wizard built into Windows XP/Vista, or a zip utility of your choice. 3) Once you have unpacked the contents of the zip archive, please launch the file AVZ.exe by double clicking on it or right clicking and selecting Open. Note: If you are running Windows vista launch AVZ.exe by right clicking and selecting Run as Administrator You should now see the main window of the AVZ utility. Please navigate to File->Custom Scripts. Copy the script below by using the keyboard shortcut CTRL+C or the corresponding option via right click. begin ExecuteStdScr(3); RebootWindows(true); end. Paste the script into the execution window by using CTRL+V keyboard shortcut, or the "paste" option via the right click menu. Click on Run to run the script, the PC will reboot. After the reboot the LOG subfolder is created in the folder with AVZ, with a file called virusinfo_syscure.zip inside. Upload that file to rapidshare.com and paste the link here. Image Tutorial -------------------------------------------------

Here is a link to the file: http://www.4shared.com/file/108634190/3eea25d0/virusinfo_syscure.html

Follow these Steps in order numbered. Don't proceed to next step unless you have sucessfully completed previous step: 1) Run this script in AVZ like before your computer will reboot. begin SetAVZGuardStatus(True); SearchRootkit(true, true); QuarantineFile('C:\Users\SENSEN~1\AppData\Local\Temp\20334.exe',''); QuarantineFile('C:\Users\SENSEN~1\AppData\Local\Temp\3328.exe',''); QuarantineFile('\\?\globalroot\systemroot\system32\gxvxcpogdrplwexhbsxxxugoqpppidtjybbqn.dll',''); DeleteFile('\\?\globalroot\systemroot\system32\gxvxcpogdrplwexhbsxxxugoqpppidtjybbqn.dll'); DeleteFile('C:\Users\SENSEN~1\AppData\Local\Temp\3328.exe'); DeleteFile('C:\Users\SENSEN~1\AppData\Local\Temp\20334.exe'); BC_ImportAll; ExecuteSysClean; BC_Activate; RebootWindows(true); end. 2) After reboot. Attach a Combofix log, please review and follow these instructions carefully. Download it here -> http://download.bleepingcomputer.co... Before Saving it to Desktop, please rename it to something like 123.exe to stop malware from disabling it. Now, please make sure no other programs are running, close all other windows and pause Antivirus/Sypware programs (http://www.bleepingcomputer.com/forums/topic114351.html Programs to disable) until after the scanning and removal process has taken place. Please double click on the file you downloaded. Follow the onscreen prompts to start the scan. Once the scanning process has started please DO NOT click on the Combofix window or attempt to use your computer as this can cause the scanning process to stall. It may take a while to complete scanning and this is normal. You will be disconnected from the internet and your desktop icons/toolbars will disappear during scanning, do not worry, this is normal and it will be restored after scanning has completed. Combofix will create a logfile and display it after your computer has rebooted. Usually located in c:\combofix.txt, please upload that file to rapidshare.com and paste the link here. -------------------------------------------------

I completed the first step with no problems, however I encountered problems with the second step. I downloaded combofix.exe and renamed it to 123.exe. When I ran the program, the console window displayed error messages saying that access was denied to certain areas and it needed administrator privileges. I got a message saying that rootkit activity was found and displayed the locations of three infected files, which I wrote down. The computer then restarted. I looked for the log but was unable to find one. There was a file in C:\ named 123 (the same as I renamed combofix to) but there was no file extension and I was unable to open it, even with notepad. I tried to upload this file but was told I do not have permission to open the file. I ran combofix a second time by right clicking it and selecting "Run as administrator" but the same thing happened. Here are the locations of the files that ComboFix displayed: C:\Windows\System32\drivers\gxvxciunvvjknfpdxcmqtexjtorkbsurtichy C:\Windows\System32\gxvxcacqfqbtsivpupmceteymbevvdjiqeqiy.dll C:\Windows\System32\gxvxcpogdrplwexhbsxxxugopppidtjybbqn.dll Thank you very much for all of your help and your quick responses.... it is greatly appreciated!
