THEN

Download and Install Combofix

Followed the instructions to the letter. Did a FSRT scan and log file attached. Then ran ComboFix which scanned and then rebooted after completion, on returning to the Desktop another window opened and started to create a log file, unfortunately it came up with an error because of disk error, damaged or something like that. I was unable to take a screenshot because my was sort of frozen and had to reboot once more. I’ve only had one pop up for the last hour or so.

essexboy · 2015-07-26T13:17:52.000Z

OK could I have a fresh FRST scan please so that I can be sure the malware has gone

system · 2015-07-26T13:32:14.000Z

Still getting pop-ups

Attached screenshot of pop-up and new Scan.

essexboy · 2015-07-26T14:34:01.000Z

OK the only thing I can think of at the moment is that an MBR type rootkit is re-installing after I am removing it

So I will check that out. Are you downloading anything after running the FRST fix ?

Download the latest version of TDSSKiller from here and save it to your Desktop.

[*]Doubleclick on TDSSKiller.exe to run the application

https://dl.dropbox.com/u/73555776/tdss%20start.JPG

[*]Then click on Change parameters.

https://dl.dropbox.com/u/73555776/tdss%20Change%20param.JPG

[*]Check the boxes beside Verify Driver Digital Signature, Detect TDLFS file system and Use KSN to scan objects , then click OK.

[*]Click the Start Scan button.

[*]If a suspicious object is detected, the default action will be Skip, click on Continue.

https://dl.dropbox.com/u/73555776/tdss%20threat.JPG

[*]If malicious objects are found, they will show in the Scan results and offer three (3) options.
[*]Ensure Cure is selected, then click Continue => Reboot now to finish the cleaning process.

[*]Get the report by selecting Reports

https://dl.dropbox.com/u/73555776/tdss%20report.JPG

[*]Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.

Please copy and paste its contents on your next reply.

Nothing found but a pop up came up while it was scanning. - Probably best thing for me is to back-up and rebuild.

Extremely greatful for your help. If you were really in Essex I’d buy a pint!

Bests

Joaquin

essexboy · 2015-07-26T15:59:47.000Z

Do you have anything on your system that is protecting the registry as that is where the malware is hiding

system · 2015-07-26T20:21:18.000Z

Sorry for the delay. I checked the services and Windows Defender was active so I switched it off, ran Adwcleaner followed by Combofix and after the reboots no more pop ups. All going well for a number of hours.

Thanks

Joaquin

essexboy · 2015-07-26T21:02:03.000Z

Could you post the combofix log please and a fresh FRST

system · 2015-07-27T16:25:44.000Z

Sorry for the delay. Will post this evening when I get home.

Regards

Joaquin

system · 2015-07-27T22:04:23.000Z

I guess I shouted victory prematurely. Last night no pop ups appeared, but this evening they are back in force.

Attached the requested files.

Regards

Joaquin

essexboy · 2015-07-28T14:13:14.000Z

This malware is normally monitored by a blank run key which is not showing in your logs. I wonder if they have now changed the monitor file.

Could you attach the combofix log as that should show any hidden entries

Thanks.

Combofix refuses to create a log and the Fix’s logs also attached.

No pop-ups so far since turning on PC 1:15 minutes ago.!

essexboy · 2015-07-28T19:22:19.000Z

Could you attach the fixlog as that is the previous scan that you have attached

system · 2015-07-28T20:20:49.000Z

Sorry about that.

essexboy · 2015-07-28T20:27:45.000Z

Well that states that it removed it successfully, so lets see if it has had the grace to give up now

system · 2015-07-28T20:32:44.000Z

So far so good. Much obliged for all your hard work.

Regards

essexboy · 2015-07-29T14:01:13.000Z

The one difference I did this time was to remove the amazon music start entry … I wonder if it was related to that
