Scammed PC advice


Recommended Posts

I recently fell for a scam and allowed a 'PC Tech Support' company access to my PC.  I have McAfee Internet Security installed and have run a full scan and a rootkit scan using their tool.  I also have run a full scan with rootkit with Malwarebytes.  Both have come up clean  and the only thing they installed is CCleaner.

I have changed all passwords to my accounts using a different machine.

Is there any other checks I should do just to be sure?

Thanks

Hello @Bartor

One should never change passwords on any computer believed to possibly be infected or compromised. Let's go ahead and do some scans and checks to make sure it's clean and then at that point I'd recommend you change passwords again.

 

Please read the following and post back the logs when ready and we'll see about getting you cleaned up.

Before we proceed further, please read all of the following instructions carefully.
If there is anything that you do not understand kindly ask before proceeding.
If needed, please print out these instructions.

  • Please do not post logs using CODE, QUOTE, or FONT tags. Just paste them as direct text.
  • If the log is too large, then you can use attachments by clicking on the More Reply Options button.
  • Please enable your system to show hidden files: How to see hidden files in Windows
  • Make sure you're subscribed to this topic:
  • Click on the Follow This Topic Button (at the top right of this page), make sure that the Receive notification box is checked and that it is set to Instantly
  • Removing malware can be unpredictable, it is unlikely, but things can go very wrong! Please make sure you Backup all files that cannot be replaced if something were to happen. You can copy them to a CD/DVD, external drive or a pen drive
  • Please don't run any other scans, download, install or uninstall any programs unless requested by me while I'm working with you.
  • The removal of malware is not instantaneous; please be patient. Often we are also in a different Time Zone.
  • Perform everything in the correct order. Sometimes one step requires the previous one.
  • If you have any problems while following my instructions, Stop there and tell me the exact nature of the issue.
  • You can check here if you're not sure if your computer is 32-bit or 64-bit
  • Please disable your antivirus while running any requested scanners so that they do not interfere with the scanners.
  • When we are done, I'll give you instructions on how to clean up all the tools and logs
  • Please stick with me until I give you the "all clear" and Please don't waste my time by leaving before that.
  • Your topic will be closed if you haven't replied within 3 days
  • (If I have not responded within 24 hours, please send me a Private Message as a reminder)

STEP 01
RKill is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes so that your normal security software can then run and clean your computer of infections.
When RKill runs, it will kill malware processes and then removes incorrect executable associations and fixes policies
that stop us from using certain tools. When finished it will display a log file that shows the processes that were
terminated while the program was running.

As RKill only terminates a program's running process and does not delete any files, after running it, you should not reboot
your computer as any malware processes that are configured to start automatically will just be started again.
Instead, after running RKill, you should immediately scan your computer using the requested scans I've included.

Please download Rkill by Grinler from one of the links below and save it to your desktop.

Link 1 | Link 2

  • On Windows XP Double-click on the Rkill desktop icon to run the tool.
  • On Windows Vista/Windows 7 or 8, right-click on the Rkill desktop icon and select Run As Administrator
  • A black DOS box will briefly flash and then disappear, this is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
  • If the tool does not run from any of the links provided, please let me know.
  • Do not reboot the computer; you will need to run the application again.

STEP 02
Backup the Registry:
Modifying the Registry can create unforeseen problems, so it's always wise to create a backup before doing so.

  • Please download ERUNT from one of the following links: Link1 | Link2 | Link3
  • ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.
  • Double click on erunt-setup.exe to Install ERUNT by following the prompts.
  • NOTE: Do not choose to allow ERUNT to add an Entry to the Startup folder. Click NO.
  • Start ERUNT either by double-clicking on the desktop icon or choosing to start the program at the end of the setup process.
  • Choose a location for the backup.
    • Note: the default location is C:\Windows\ERDNT which is acceptable.
  • Make sure that at least the first two check boxes are selected.
  • Click on OK
  • Then click on YES to create the folder.
  • Note: if it is necessary to restore the registry, open the backup folder and start ERDNT.exe

STEP 03
Please run a Threat Scan with MBAM. If you're unable to run or complete the scan as shown below, please see the following:
MBAM Clean Removal Process 2x
When reinstalling the program, please try the latest version.

Right click and choose "Run as administrator" to open Malwarebytes Anti-Malware and from the Dashboard please Check for Updates by clicking the Update Now... link
Open up Malwarebytes > Settings > Detection and Protection > Enable Scan for rootkit and Under Non Malware Protection set both PUP and PUM to Treat detections as malware.
Click on the SCAN button and run a Threat Scan with Malwarebytes Anti-Malware by clicking the Scan Now>> button.
Once completed please click on the History > Application Logs and find your scan log and open it and then click on the "copy to clipboard" button and post back the results on your next reply.

the computer has been running fine.  I hadn't seen any signs of a virus or anything and had run McAfee and MBAM before but wanted to get some expert advice to see if there was anything else I should check to make sure nothing malicious had been planted in it.

Thanks you for your advice and guidance.

At this time there are no more signs of an infection on your system.
However if you are still seeing any signs of an infection please let me know.

Let's go ahead and remove the tools and logs we've used during this process.

Most of the tools used are potentially dangerous to use unsupervised or if ran at the wrong time.
They are often updated daily so if you went to use them again in the future they would be outdated anyways.

The following procedures will implement some cleanup procedures to remove these tools.
 
bwebb7v.jpgDownload Delfix from here and save it to your desktop. (you may already have this)

  • Ensure Remove disinfection tools is checked.
  • Click the Run button.
  • Reboot


Any other programs or logs that are still remaining, you can manually delete. (right click.....Delete)
IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST folder, FRST-OlderVersion folder, MBAR folder, etc....AdwCleaner > just run the program and click uninstall.


 
If there are any other left over Folders, Files, Logs then you can delete them on your own.
 
Please visit the following link to see how to delete old System Restore Points. Please delete all of them and create a new one at this time.
How to Delete System Protection Restore Points in Windows 7 and Windows 8

Remove all but the most recent Restore Point on Windows XP

A lot of reading here but if you take the time to read a bit of it you'll see why/how infections and general damage are so easily inflicted on the computer. There is also advice on how to prevent it and keep the system working well. Don't forget about good, solid backups of your data to an external drive that is not connected except when backing up your data. If you leave a backup drive connected and you do get infected it can easily damage, encrypt, delete, or corrupt your backups as well and then you'd lose all data.
Nothing is 100% bulletproof but with a little bit of education you can certainly swing things in your favor.


If you're not currently using Malwarebytes Premium then you may want to consider purchasing the product which can also help greatly reduce the risk of a future infection.
