Re-occurring virus... Even after a format.


Recommended Posts

I'm using Windows 10.

I got a virus last week. Really nasty. It deleted malware-bytes & avast, prevented me from copying files, added an administrator account, prevented me from accessing certain websites, etc, etc.
Chameleon wouldn't run, any programs that might have gotten rid of it were deleted. USB drive with any relevant files resulted in a USB drive that wouldn't show up in explorer.

I decided I wasn't going to deal with it so I formatted. Two days later, got it again.

I installed a fresh windows 10 (legal), Steam, Dropbox, Malware-Bytes, and Google drive. Nothing else.

I haven't used the USB drive again, I haven't done anything but access websites I usually access... nothing shady. After the fresh install I ran a full scan from the paid version of Malware Bytes. Everything came up clean. Downloaded the paid version of bit defender, full scanned the whole computer. Everything clean. 

Virus comes back during a copy of old files from D drive. All the same symptoms, all antivirus is deleted, etc, etc.

I reformat, do it all again. Virus comes back and i'm able to confirm how to reproduce it.

I've found that I can reproduce my machine becoming unusable by copying files from one hard drive to the other. It will freeze on a random file. Canceling just freezes up explorer, then everything flickers and stops running until a restart happens. Upon restarting windows shows no icons, all anti virus is uninstalled, (This time both malware bytes & bitdefender) and I'm unable to use my computer until a couple more restarts. Eventually, I can get into windows and I am no longer the administrator. A new account is on my computer and all anti virus is gone and unreachable.

Any advice on how to clean infected files would be nice. Otherwise I guess I have to just format everything, even stuff that wasn't on C:. This would result in data loss of both backups and current files. Nothing is encrypted, but I cannot copy it without windows exploding. Anti virus, anti malware all comes up negative.

UPDATE: I'm thinking my files might be slowly being encrypted. I've run CryptoLocker Scan Tool, it says that many files may be encrypted. If ran, or copied, these files seem to reinstall whatever the virus is and the encryption process starts again. I'm reading about ransom-ware and people are saying that it isn't supposed to self replicate like that... Just letting everyone know my observations.  

I hope i'm wrong. I hope that the "may be encrypted" is a false positive. But anytime a file is copied, my computer freezes, and all anti virus is deleted. Nothing is ever detected as a virus before hand. 

What am i missing?

Hello hoduken and welcome to Malwarebytes,

Download and install McShield from here: http://mcshield.net/ that is a free to use tool that will run in the background and help to stop cross infection from USB devices, Hard drives etc...


Can you tell me if this program is known to you and trusted: GoTo Opener


Open Malwarebytes, from the main interface select > Scan > Custom Scan > Configure Scan > Ensure the following are all Checkmarked :-
  • Scan Memory
  • Scan Startup and Registry Settings

Also ensure all Hard Drives are selected...

When all of those settings are chemarked select "Scan Now" option....

Make sure any found entries are quarantined, also reboot if prompted...

To get the log from Malwarebytes do the following:
  • Click on the Reports tab > from main interface.
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply

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)

The Virus Removal Tool scans the following areas of your computer:

  • 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

Thank you,

thanks for the reply. 

I've followed your instructions. Goto Opener is gotomypc. It's legit.

I formatted again. Fresh install. All drives formatted. On first boot explorer is redirecting to malicious sites and crashes over and over. Anti virus didn't catch any issues. I can attach the files if you'd like. 

Mcshield does detect one of my usb sticks has a virus. Though, after the message comes up it says its clean... it's not though. The message that its infected comes up everytime i plug it in. No antivirus detects anything on it. Not sure how I can clean it if mcshield, bitdefender, and malwarebytes doesn't see anything.

Any thoughts?

Drive d: (Storage & Games) (Fixed) (Total:3725.9 GB) (Free:2314.12 GB) NTFS

Drive g: (ESD-USB) (Removable) (Total:7.45 GB) (Free:3.35 GB) FAT32 <-------- Is that usb used to reinstall windows...?
