This is for a shared work computer. I have administration rights and Firefox is used usually for internet browsing.

I have Mcaffee Virus Scan and lately when logging into the internet, an error has been pooping up that a Trojan has been removed and then the browser I'm using, whether IE or Firefox, then shuts down. I have done a full scan of the computer twice now, and no positive results of an infection have occurred. Mcaffee is up to date on everytihng and a paid version.

Additionally, I have installed two other Virus Scan programs (Avira AntiVir Personal - Free Antivirus and AVG Anti-Virus Free Edition
) to see if they can find anything, but when I try to update their virus definitions, I get a connection error. So, I can't update the virus scan virus information.

What can I do? I am currently running full scans Ad-aware Anniversary Edition and Malwarebyte's Anti-Maleware.

Here is the McAfee notification that pops up:

McAfee has automatically blocked and removed a Trojan.

About this Trojan
Detected: Lando (Trojan), Lando (Trojan)
Location: C:\WINDOWS\system32\setup_u.exe

Trojans appear as legitimate programs but can damage valuable files, disrupt performance, and allow unauthorized access to your computer.

You should only have one AV installed on the computer
------------------------------------

The process of cleaning your computer may require you to temporarily disable 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

I ran a Full Scan MBAM and it pulled up the same infected item as the Quick Scan, after it had been removed and deleted from the quick scan.

The same Trojan is still popping up whenever I run the MBAM, even now.

Okay, I fixed the issue by following instructions on a post with similar issues. I did the following to fix my sjr.vxn Trojan.Daonol virus issue:


* Double-clicked the renamed regedit.exe to run it (a copy of regedit.exe that was renamed to copy.exe because accessing regedit.exe was not possible). The registry editor opened.
* In the left pane, navigated to the following sub-key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32

* Highlighted Drivers32 sub-key. In the right pane under Name there was a value named aux2. Right-clicked on it, selected Delete
* Confirmed the deletion and closed the registry editor.
* Rebooted computer and located the following file: C:\WINDOWS\sjr.vxn
* Deleted the file.


This resolved the issue and I am now able to update McAfee and the computer and internet is now functioning normally. I ran an Ad-aware scan again, as well as a McAfee Virus scan.
