okay, i'm brand new to this forum, so if i'm doing something wrong please let me know, i apoligize in advance.



basically, my computer is slowly being destroyed by this trojandowloader:win32/renos.dl virus

I remove it, and it comes back 2 hours later. It hasn't downloaded anything to my computer to my knowledge(unless they're hidden well).

But instead, it's been crashing programs and windows on my computer, slowing processes, and the newest one is i now can't watch videos and it's giving me server execution failed when i attempt to open a video file.

I'm running a virus removal tool right now and i just had these 2 come up:
trojan.win32.agent2.cyqm
heur:trojan.win32.generic
When I deleted the .agent2 one a message popped up saying that it keeps creating a backup file, and i'm not sure if they're removing.

So I basically have no idea what to do at this point..
Anything, I MEAN ANYTHING, would help. PLEASE!

I'm running a virus removal tool right now

Hello and :welcome: to the BC forums.

What is the name of the "virus removal tool" that you are running?

Please do the following:

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 1: 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 of whether you are 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

Please post the log and let us know how your computer is running now.

I'm running the latest free Kaspersky Virus Removal Tool, initially to just get a deeper scan of my computer.

And I'm downloading MB right now

Thank you.

Please do not attempt to run more than one anti-malware scan at a time.

Please wait until Kaspersky has finished its scan and removed the malware that it has found.
Restart the computer after that. <<< Important
Then post the log or attach it to your post if it is excessively long.
(You may need to zip it up if you are going to attach a log file, as opposed to a text file.)

Then start MBAM: Check for updated definitions again.
Start the MBAM scan.
When that has finished scanning, remove what it has found.
Post a copy of the log.
Restart the computer. <<< Important

Thank you.

Fine.

Let us know how your computer is running then, and whether there are any signs of malware still being present in the system.

Alright, Here is Kaspersky. But there's something weird about this, I've had these files downloaded for around 5 months now, is it likely that they've just been hiding and are just now starting to affect my computer? let me know what you think... Because, in the past, I was hit with a large amount of trojans, and my Kaspersky was basically demolished and kept giving me false alerts and what not. So with my past experiences I wasn't sure if I should trust it or not, but I read it's one of the best free ones out there, so I went ahead and did it.

I'm gonna restart my computer now and see if anythings faster and the problems are fixed.
Is there anything I should do now to make sure I've rid of everything, or am I just gonna have to wait and see if further problems arise?

Let's make sure there is nothing else hiding on the system by running a couple more scans.

:step1: Empty your temp folders using TFC (Temporary File Cleaner) in Safe Mode
  • Please download TFC by Old Timer and save it to your desktop.
    alternate download link
  • Re-start your computer and load Windows in Safe Mode:
    • Start tapping the F8 key as the system starts to boot again, and continue tapping until you are presented with the "Windows Advanced Options Menu" screen.
    • Use the UP/DOWN arrow keys to select "Safe Mode", and press the <ENTER> key.
    • Log into your own account.

      Getting into Windows Safe Mode
      http://www.computerhope.com/issues/chsafe.htm
  • Run TFC:
    • Save any unsaved work. (TFC will close ALL open programs including your browser!)
    • Double-click on TFC.exe to run it. (If you are using Vista, right-click on the file and choose "Run As Administrator".)
    • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
    • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway allowing Windows to load normally (not into Safe Mode) to ensure a complete clean.

:step2: Please download 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.


:step3: Scan your machine with ESET OnlineScan
  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Posted Image to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • 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 Posted Image
  • Push Posted Image, 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 Posted Image button.
  • Push Posted Image

Note 1: A log.txt file will also be created and automatically saved in the C:\Program Files\EsetOnlineScanner\ folder.
If you did not save the ESETScan log, click Posted Image > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt in your next reply.

NOTE 2: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

NOTE 3: In some instances if no malware is found, there will be no log produced.


Please post the logs and let us know how your system is running.
