Hi picasso :)

 

My reference was to this line in a Search.txt log:

C:\Users\Public\Documents\iWin\engine\QwMSjsxFAJ.b3e3
[2016-11-11 19:00][2016-11-11 19:00] 0006036 ____A () A91761697A10479462BBF4A67AC337A4 [File not signed]

I understand that the archive bit is not helpful at all in this sense but I just wanted to make sure that the A actually meant what I thought it meant.

 

Thanks for your assistance.

The tutorial description refers to FRST.txt output only. "A" is not present in FRST.txt log. But yes, the attribute is still listed in Search.txt log.

 

EDIT: Later removed too.

I'm a long time ComboFix user and as everyone knows by now it doesn't work on Windows 10 and probably all versions thereafter.   I would like to learn to fish and not just eat one day.  I reviewed a few post and the forum is helpful with helping people out with getting them the fixlist.txt that will correct their problem but not with actually teaching them how to do it themselves and what to look out for.  Below is FRST from a computer recently obtained.  Can anyone mark the entries they would paste to the Fixlist.txt and provide a brief reason why?

 

Edit

 

Log removed see post #144.

This topic is not meant to provide any logs analysing. Please see posts #85 and #116.
 

If you are interested in learning about malware removal you might consider applying to one of the training institutions.

Go here to find a list of approved malware removal schools.

 
 

For now I moved the log you posted to the spoiler. But I think it should be removed.

Hello and welcome to Geekstogo DARYLN357357,

 

I confirm picasso's comments.

 

You can open a topic here if you wish help with that log. Alternatively if you are looking to learn about fighting malware you can apply to one of the schools listed in the link picasso provided.

 

As this is not the place for log analysis I have removed it from your post.

 

regards

emeraldnzl :)

Does This Directive can be used in Recovery Environment? Although that the Alternate Data Streams Scan is not available in Recovery.

AlternateDataStreams:

Refer to "Default Scan Areas". You can't take detections specific only for Addition.txt not produced in Recovery Environment and process them from Recovery Environment. And that is not a directive in a meaning used in the tutorial: you can't type "AlternateDataStreams:" with a path not detected by FRST (manually chosen by you), only lines visible in Addition can be processed.

I have not had to use FRST in the Recovery Environment now for a long time. However, I recently ran across an infection that was proving difficult to remove in Normal Mode so I went ahead and updated the canned message a little and thought I would share.

Maybe FRST can add a directive, which it can place a dummy file (same name and extension) after move a file to quarantine.

 

Thank you..

I am not sure of the purpose of that.

 

Perhaps I am missing something. Can you say why you are suggesting that?

I'm also not sure what is the purpose of that. Anyway, you can already imitate that functionality using command line directives (eg. Powershell). To create an empty file (path and file name to be filled) :

 

Powershell: New-Item -Path FolderPath -Name FileName -ItemType File

 

If needed, other extra commands could be added to lock the file ("R" attribute + permissions).

I understand the purpose of that. It might be useful sometimes when a bad file will be recreated after removal.  Of course the dummy should be removed after completing the removal when the infection doesn't return any more.

It will be included in the next update.

The directive is:

CreateDummy: path

 

Example:
 

CreateDummy: C:\ProgramData\test.exe

 

The dummy is a locked folder with hidden, write protected and system attributes.

Yes, the purpose of create a dummy file is like that.

 

Sometimes when we has deleted any bad file, it will be recreated. Due to User fault (accidentially run a bad file again in another Drive) or due to this sistem still have another bad process that still running. It will mess our fix.

 

 

The directive is:

CreateDummy: path

 

Example:
 

CreateDummy: C:\ProgramData\test.exe

 

The dummy is a locked folder with hidden, write protected and system attributes.

 

Thank you, you're very responsive.

 

 

The dummy is a locked folder with hidden, write protected and system attributes.

 

 

I already try it and yes, this folder is Write Protected. But i just wondering how can it be? Is it due to permission set like Picasso just said above?
