Just received alert that looks as though it's from Windows Security. Address is: Link removed by moderator

Said my computer is infected with over 200 trojans and other viri and malware.

How can I tell whether this is for real? Seems scammy but I don't know. Am running avira but nothing has shown up yet.

Another popup now says Warning! Your computer contains various signs of viruses and malware programs presence. Microsoft Security Assessment Toll will perform a quick and free online checking of your pc.

The bugger just "scanned" my computer and told me to download program to remove all the viri. Yikes!

Thank you.

Thank you.

Malware didn't find anything. Could it have missed something?

Or, were the popups a marketing thing to sell software to unsuspecting newbies?

Hello there :cool:
My name is NeonFx. I'll be glad to help you with your computer problems. Logs can take some time to research, so please be patient with me.


Please note the following:
  • The fixes are specific to your problem and should only be used on this machine.
  • Please continue to review my answers until I tell you your machine appears to be clean. Absence of symptoms does not necessarily mean that the system is completely clean.
  • It's often worth reading through these instructions and printing them for ease of reference. I may ask you to boot into Safe Mode where you will be unable to follow my instructions online.
  • If you don't know or understand something, please don't hesitate to say or ask!! It's better to be sure and safe than sorry.
  • Please reply to this thread. Do not start a new topic.



Step 1

Download OTS to your Desktop

  • Close ALL OTHER PROGRAMS.
  • Double-click on OTS.exe to start the program.
  • Check the box that says Scan All Users
  • Under Basic Scans please change the radio button under Registry from Safe List to All.
  • Under Additional Scans check the following:
    • Reg - Desktop Components
    • Reg - Disabled MS Config Items
    • Reg - NetSvcs
    • Reg - Shell Spawning
    • Reg - Uninstall List
    • File - Lop Check
    • File - Purity Scan
    • Evnt - EvtViewer (last 10)
  • Please paste the contents of the following codebox into the Custom Scans box at the bottom
Code:
%SYSTEMDRIVE%\*.exe
/md5start
eventlog.dll
scecli.dll
netlogon.dll
cngaudit.dll
sceclt.dll
ntelogon.dll
logevent.dll
iaStor.sys
nvstor.sys
atapi.sys
IdeChnDr.sys
viasraid.sys
AGP440.sys
vaxscsi.sys
nvatabus.sys
viamraid.sys
nvata.sys
nvgts.sys
iastorv.sys
ViPrt.sys
eNetHook.dll
ahcix86.sys
KR10N.sys
nvstor32.sys
ahcix86s.sys
nvrd32.sys
symmpi.sys
adp3132.sys
mv61xx.sys
/md5stop
%systemroot%\*. /mp /s
CREATERESTOREPOINT
%systemroot%\system32\*.dll /lockedfiles
%systemroot%\Tasks\*.job /lockedfiles
%systemroot%\system32\drivers\*.sys /lockedfiles
%systemroot%\System32\config\*.sav
  • Now click the Run Scan button on the toolbar.
  • Let it run unhindered until it finishes.
  • When the scan is complete Notepad will open with the report file loaded in it.
  • Click the Format menu and make sure that Wordwrap is not checked. If it is then click on it to uncheck it.
Please attach the log in your next post. To do so click on the blue "Reply" button or "Go Advanced" and click on the "Manage Attachments" button

Step 2

GMER Rootkit Scanner
Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs. Make sure you disable your security programs as well, as they may interfere with the program.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.


  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable your security programs when done.


If you have trouble running GMER, please try running it in Safe Mode. To get to Safe Mode you'll need to repeatedly tap the F8 key on your keyboard as you turn your computer on until a black and white menu appears with the option.

If you continue to have trouble with it, try running it without the "Files" scan checked.

Alright. Let me know if you have trouble with GMER after you've tried it in Safe Mode and without the "Files" scan checked.

OK. Tried it and, after a long time a message flashed on that the program was doing something to my system and my computer went down. Let it sleep all night and will try again now. Thank you.

Tried several times (all morning) with and without files and safe mode. Windows shut down with blue screen saying they are protecting my computer. Couldn't save screenshot because computer went off and rebooted.

Is there another scanning program I can use? Did anything show up in ots scan? Thank you.

Let's try the following program. There are a couple infections that only GMER will see and that's why I was wanting you to try it several times. Sorry for the trouble.

Download RootRepeal from one of the following locations and save it to your desktop:
  • Double click
    to start the program
  • Click on the Report tab at the bottom of the program window
  • Click the
    button
  • In the Select Scan dialog, check:


    • [*]Drivers
      [*]Files
      [*]Processes
      [*]SSDT
      [*]Stealth Objects
      [*]Hidden Services
      [*]Shadow SSDT
  • Click the OK button
  • In the next dialog, select all drives showing
  • Click OK to start the scan
    Note: The scan can take some time. DO NOT run any other programs while the scan is running
  • When the scan is complete, click the
    button and save the report to your Desktop as RootRepeal.txt
  • Go to File, then Exit to close the program

If the report is not too long, post the contents of RootRepeal.txt in your next reply. If the report is very long, it will not be complete if you post it, so please attach it to your reply instead.

You can allow that, it's normal. It's one of Windows' components.

You did good. Let's start fixing:


NOTE: ComboFix should NOT be used without supervision by someone trained in its use. It does a whole lot more to a system than just remove infected files.

Download ComboFix from one of these locations:

Link 1
Link 2


* IMPORTANT !!! Save ComboFix.exe to your Desktop



  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. Note: If you are having difficulty properly disabling your protective programs, or are unsure as to what programs need to be disabled, please refer to the information available through this link : Disabling Security Programs
  • Double click on ComboFix.exe & follow the prompts.

    Note: Combofix will run without the Recovery Console installed.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.


**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.




Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:




Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.

Notes:

1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. ComboFix may reset a number of Internet Explorer's settings, including making I-E the default browser.
3. Combofix prevents autorun of ALL CD, floppy and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you please let me know. A increasing number of infections are spreading using Autoplay and leaving it disabled is a good idea.
4. CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.
