Forged Physical Sector

[mercat]

Malwarebytes Anti-Malware and Anti-Rootkit caught the forged physical sector threat and the location is Master Boot Sector on volume #0.  The threat was caught again after applying the suggested cleaning option and the computer restarted.  This has gone on for over two weeks. Please help!  Thanks

Hello,

They call me TwinHeadedEagle around here, and I'll be working with you.

Before we start please read and note the following:

Limit your internet access to posting here, some infections just wait to steal typed-in passwords.

Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time.

Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.

Do not paste the logs in your posts, attachments make my work easier. There is a Attach Files option below which you can use to attach your reports. Always attach reports from all tools.

Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.

Note that we may live in totally different time zones, what may cause some delays between answers.

Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.

If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

I can't foresee everything, so if anything unexpected happens, please stop and inform me!

There are no silly questions. Never be afraid to ask if in doubt!

Can I see that report?

I need you to run one more tool:
 

 

 

Scan with TDSSKiller

Please download TDSSKiller by Kaspersky and save it to your desktop.
 

• Right-click on icon and select Run as Administrator to start the tool.
• Click on Change parameters and put a checkmark beside Loaded modules. A reboot will be needed to apply the changes, allow it to do so.
• Your machine may appear very slow and unusable after that - it's normal.
• TDSSKiller will run automaticaly. Click on Change parameters and click OK.
• Click the Start Scan button and wait patiently.

If anything will be found follow this guidelines:

• If a suspicious object is detected, the default action will be Skip, click on Continue.
• If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  If Cure is not available, please choose Skip instead.
• Do not choose Delete unless instructed!

A report will be created in your root directory, (usually C:\ drive) in the form of TDSSKiller.[Version]_[Date]_[Time]_log.txt. Please include the contents of that file in your next post.

Attached are the logs.

That looks clean, let's run one more tool for final scan:

Please download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatibale with your system. 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.

• Double-click to run it. When the tool opens click Yes to disclaimer.
• Press Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
• The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

Hi,

Your PC seems clean, there is no active malware

[mercat]

Two days ago scan using Malwarebytes Anti-Malware and Anti-Rootkit did not catch the forged physical disk. Today scan using Anti-Malware was negative.  However, today scan using Anti-Rootkit was positive.

 

Could it be the Acronis True Image 2013 imaging of mechanical hard drive to SSD hard drive causing the intermittent positive result?  The SSD is OCZ Vertex 460.  BTW, I scanned the mechanical hard drive and there was no positive result.

[TwinHeadedEagle]

Yes, it could be some false detection, because we checked with two Rootkit scanners and there is no threat.

 

If everything is ok now, we can finish?

[mercat]

Yes.  Thanks again.

Click Run button and wait a few seconds for the programme completes his work.
