n65adserv virus

[frankp]

Over the weekend, I was infected with the n65adserv virus.   It blocked Malwarebytes, deleted entries for restore.  It apparently deleted the chameleon file.  What next?

Kevin, I have tried twice to get the F Bar tool but each time the system restarts.  I have premium version btw

 

[kevinf80]

What version of windows do you have, is it 32 or 64 bit. Do you have access to another working PC, also a USB flashdrive...

[frankp]

I have a 64 bit system.  Downloaded FARBAR from another computer to flash drive. Tried to run it both as a file and from the flash drive.  Both times is immediately closed down, much as Malwarebytes does.

[kevinf80]

Please download Farbar Recovery Scan Tool from here: http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/ save it to a USB flash drive. Ensure to get the correct version for your system, 32 bit or 64 bit... Next, From your Desktop select the start Flag (bottom lefthand corner of screen) Hold down the "Shift key" of your keyboard, keep it down and select "Restart" Your PC should open to the "Choose an Option" window.... release shift key. From that window select "Troubleshoot" From the next window select "Advance Options" From that Window select "Command Prompt" Ensure to plug the flash drive into a USB port... You should now be in Recovery Environment with the Command Prompt Window open...... Continue with the following:   In the command window type in notepad and press Enter. The notepad opens. Under File menu select Open. Select "Computer" and find your flash drive letter and close the notepad. In the command window type E:\frst64 or E:\frst depending on your version. Press Enter Note: Replace letter E with the drive letter of your flash drive. <<<----vey important The tool will start to run. When the tool opens click Yes to disclaimer. Press Scan button. It will make a log (FRST.txt) on the flash drive. You will need to boot back to Normal windows to post the log, or if applicable do that action from a spare PC... To boot back to windows, type exit at the prompt and hit enter Please copy and paste or attach FRST log to your reply. Thanks, Kevin...

Kevin, I went to the Bleep site, down  loaded the F tool to a thumb drive.  Took to my computer and moved it to a file site and tried administrator load. It was shut down immediately after a flashing scan page.  I  tried to run it from the thumb drive and got the same  results.  Appears there are a list of programs this virus has that stops them from operating.  Frank

Hiya Frank,

Can you follow the instructions from my last reply and run FRST (from Flashdrive) via Windows Recovery Environment...?

Thank you,

Kevin..

[frankp]

I was able to run the FRST64 on  the thumb drive using safemode with command.

FRST.txt

[kevinf80]

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

Boot back to Normal mode, run FRST again and post both produced logs FRST.txt and Addition.txt

Run FRST one more time, ensure all boxes are checkmarked under "Whitelist" but only Addition.txt under "Optional scan" Select scan, when done post the new logs. "FRST.txt" and "Addition.txt"

Let me see those logs in your reply...

Thanks,

Kevin...

 

fixlist.txt

[frankp]

Here are the fixit log from the first FRST64 run under safe mode and then the logs run the next time.  I am running the third time now and will send that separately.

Fixlog.txt

Addition.txt

FRST.txt

Thanks, post fresh logs whenever ready...

Here are the frst64 txt and addition from the last try.

[frankp]

Thank  you, Kevin.  I did the delete & install of Chrome yesterday and will go back to add the items in your message.

You recall Malwarebytes was changed by the virus so it would not open.  After the remedial items done earlier, it would still not start the web protection and kept turning off the root kits  one. I deleted the root kit errors and then I ran the MB clean ap.  Subsequently I did a new mb restore manually and it worked.  I ran it several times and all protections seemed to be working..

I will run the fixes  in this message and let you know if any problems and if there are any restore points added. Thanks for  your help.

Frank

[kevinf80]

Cheers Frank, unless you have any remaining issues or concerns run the following to clean up...

Download "Delfix by Xplode" and save it to your desktop. Or use the following if first link is down: "Delfix link mirror" If your security program alerts to Delfix either, accept the alert or turn your security off. Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator Make Sure the following items are checked:   Remove disinfection tools <----- this will remove tools we may have used. Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created. Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection Now click on "Run" and wait patiently until the tool has completed. The tool will create a log when it has completed. We don't need you to post this. Any remnant files/logs from tools we have used can be deleted… Next, Read the following links to fully understand PC Security and Best Practices, you may find them useful.... Answers to Common Security Questions and best Practices Do I need a Registry Cleaner? Take care and surf safe Kevin...
