Reinfestation even after secure erase of hdd and replacing router.


Recommended Posts

So,  I foolishly tried a hacked piece of software.  I have some kind of terrible problem.  I did everything I can think of,  even booting to a USB with Parted Magic distro and choosing "Secure Erase"  option for my entire hdd. It took 3hours to complete. When finished, I installed Win10, a different os than before (Win7 originally). I also replaced my router with another I had.  

All seemed well until I tried to install Chrome. 

The install didn't fully complete because the Google home page never opened.  Instead I saw a "security alert" pop up and multiple things appear in Task Manager. 

 

The computer makes noises too,  from the speakers,  a kind of ticking. 

 

I'm afraid everything on my home network is ruined. 

 

The person behind this already tried to withdraw money from my bank. 

Please take a bit of pity on me and help me,  I can't even figure out what I'm dealing with....

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status...
 
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)

Let me see those logs in your reply...

Thank you,

Kevin: Thanks for the reply.  I don't have Windows installed any more, I've nuked the hdd for the second time.  

When I did,  I couldn't get to the desktop even before dozens of instances of weird programs would start and use all the resources. 

I could boot in safe mode but nothing I tried in safe mode "stuck" after a reboot.

I'm going to try a *second *fresh install in 9 hours after the nuke is complete,  but I am really at my wits end.  I've already done a fresh install of Win10,  after Parted Magic "secure erase" using hdpharm (sp ?), and I had all the signs of an attack as soon as I tried to install Chrome.  

I don't even have a clue what I'm dealing with... Is it something some how left even after a secure erase?  Is it in my Google account?  My cable modem?

What is happening with the initial PC you listed...?

For the second PC run the following, make intial FRST Fix from Safemode with NW:

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 when running FRST fix"
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 to Normal mode and run this:

Please download Zemana AntiMalware and save it to your Desktop.
 
  • Install the program and once the installation is complete it will start automatically.
  • Without changing any options, press Scan to begin.
  • After the short scan is finished, if threats are detected press Next to remove them.
    Note: If restart is required to finish the cleaning process, you should click Reboot. If reboot isn't required, please re-boot your computer manually.
     
  • Open Zemana AntiMalware again.
  • Click on user posted image icon and double click the latest report.
  • Now click File > Save As and choose your Desktop before pressing Save.
  • Attach saved report in your next message.


Next,

Again from Normal mode:

Download Sophos Free Virus Removal Tool and save it to your desktop.

If your security alerts to this scan either accept the alert or turn off your security to allow Sophos to run and complete.....

Please Do Not use your PC whilst the scan is in progress.... This scan is very thorough so may take several hours...
 
  • Double click the icon and select Run
  • Click Next
  • Select I accept the terms in this license agreement, then click Next twice
  • Click Install
  • Click Finish to launch the program
  • Once the virus database has been updated click Start Scanning
  • If any threats are found click Details, then View log file... (bottom left hand corner)
  • Copy and paste the results in your reply
  • Close the Notepad document, close the Threat Details screen, then click Start cleanup
  • Click Exit to close the program
  • If no threats were found please confirm that result....



The Virus Removal Tool scans the following areas of your computer:
  • Memory, including system memory on 32-bit (x86) versions of Windows
  • The Windows registry
  • All local hard drives, fixed and removable
  • Mapped network drives are not scanned.


Note: If threats are found in the computer memory, the scan stops. This is because further scanning could enable the threat to spread. You will be asked to click Start Cleanup to remove the threats before continuing the scan.

Saved logs are found here: C:\ProgramData\Sophos\Sophos Virus Removal Tool\Logs

Let me see those logs from the second PC, also give me an update on the first PC...

Thank you,

Kevin..

Ok, done all you asked, but the last one needed a reboot to clean and I forgot to get the log before I did, so they're backwards in order.

 

I'm becoming convinced this was malware installed to Google/Chrome backups. I deleted all of my Chrome auto save stuff, and I'm going to abandon my old Gmail/Google account too. I can't believe Google would make such a vicious infection possible, I don't need any of their data gathering "features" and only ever really used them just because I was too lazy to turn them off...

All the stuff found on my "second" computer  has been there for years, as the files shown are all old stuff that I know I made myself.

I'm going to cautiously say, yes, they're both recovered. 

 

I wish now I hadn't panicked so badly and totally wiped the hdd of my first computer. I'm convinced it was all Google/Chrome based issue infection/re-infection.

I'm on my second reinstall of a whole different OS on this first computer, and so far, without Chrome installed, there are no signs of any re-infection. 
I'm still dumbfounded at Google/Chrome.

Last question, is there any way to know for sure what I was attacked with ? 

There were dozens of instances of a program identifying itself as Impersario.exe  in my TaskManager while the attack was taking place, that's the only thing I can clearly remember about it.

Hiya Gn2,

Going off your explanation of what happened I believe your Chrome Browser was the problem, a nuke and repave of your hard drive with a fresh windows 10 install would not carry over the infection. Unfortunately reinstalling Chrome and resyncing has been seen many times to reintroduce an exploited account.

If you want to use Chrome again you will have to sign into your Google account from a different Browser and delete your "Synced" data. To me that is the only option that will ensure all exploitations are cleared. Personally I never use Chrome, I use Firefox and have done so for several years

Go to this link from different Browser: https://chrome.google.com/sync  and sign into your Google account. In the new window scroll "Reset Sync" that will remove all of your synced data from Googles servers...

For the second PC you can do the following to remove programs we may have used and reset system settings that may have been changed by Malware...

Uninstall Sophos AV and Zemana http://www.askvg.com/how-to-completely-uninstall-remove-a-software-program-in-windows-without-using-3rd-party-software/

Also delete this folder if still present: C:\ProgramData\Sophos

Next,

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…
