upon opening my external hard drive I found a file of 117G missing. The hard drive usage was the same as usual but the file was no longer listed. After I went through the rest of the drive I found that the original file had been placed into another unknown file. along with the my original file were these two programs? mrtstub.exe. & mrt.exe._p   I ran both Bitdefender and Malwarebytes both showed no virus. I googled them and found contradicting views on whether they are virus or not. I also tried to delete them but was not able to. What are they, why did they hide my file in another. and how do I get rid of them?

 

am new to Windows 7 and not versed on how to do so.

 

Thanks for any help

Do you have the file size correct?  I know of no Microsoft file that would be 117GB.

no its not a Microsoft file. its a folder containing jpeg's and pdf's on my hard drive. Moving beyond that what is mrtstub.exe anyway, is it a virus or not and why cant I remove it and its fellow traveler the mrt.exe._p both.

Try deleting in safe mode.  If you read the link I provided, that defines what it is.  If the folder containing these files is located in C:/Windows/system32, it's valid.

Those files are leftovers from the Microsoft Malicious Software Removal tool.  But if this doesn't have a digital signature it can be malware.

 

Do you have the Microsoft Malicious Software Removal tool installed, if you do have you used it?


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

I have used the Micro MSR tool  of and on but don't have it installed now. Thanks for clearing it up.
