Hello,


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.

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 Upload a File button which you can use to attach your reports. Attach all reports.

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.

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!



I still need Addition.txt report.

Sorry Thought i attached this file already.

First, go to Control Panel and uninstall following (skip lines that cannot be uninstalled):
- Advanced SystemCare 7
- IObit Uninstaller
- File Type Assistant
- Mozilla Firefox Free Download Packages

Fix with Farbar Recovery Scan Tool

This fix was created for this user for use on that particular machine.

Running it on another one may cause damage and render the system unstable.

​

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

• Right-click on
  
  icon and select
  
  Run as Administrator to start the tool.
  (XP users click run after receipt of Windows Security Warning - Open File).
• Press the Fix button just once and wait.
• If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
• When finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please attach it to your reply.




Please download AdwCleaner by Xplode and save to your Desktop.

Double click on AdwCleaner.exe to run the tool.

• Click on the Scan button.
• After the scan has finished click on the Clean button.

Press OK when asked to close all programs and follow the onscreen prompts.
Press OK again to allow AdwCleaner to restart the computer and complete the removal process.

• After rebooting, a logfile report (AdwCleaner[S0].txt) will open automatically.
• Post logfile will also be saved in the C:\AdwCleaner folder.

Hello,

Followed your instructions.
- File Type Assistant was not in the list, so i could not remove this one

attached are the requested log files.
Have not started Google Chrome yet, will wait until you say it is ok to do so.

 

[TwinHeadedEagle]

Run Chrome now and tell me how is it going?

 

[f.van.zwol]

Nothing changed.
Still the same symptoms.

Scan with ZOEK

Please download ZOEK by Smeenk and save it to your desktop (preferred version is the *.exe one)
Temporary disable your AntiVirus and AntiSpyware protection - instructions here.

• Right-click on
  
  icon and select
  
  Run as Administrator to start the tool.
• Wait patiently until the main console will appear, it may take a minute or two.
• In the main box please paste in the following script:
  

  createsrpoint;
  process;
  services-list;
  installedprogs;
  systemspecs;
  startupall;
  filesrcm;
  firefoxlook;
  chromelook;
  skipfix-iedefaults;

• Make sure that Scan All Users option is checked.
• Push Run Script and wait patiently. The scan may take a couple of minutes.
• When the scan completes, a zoek-results logfile should open in notepad.
• If a reboot is needed, it will be opened after it. You may also find it at your main drive (usually C:\ drive)

Attach report into your next reply.

here is the log file from zoek.exe

Okay, run one more Zoek script on the same way:

Surfing Protection;u
LiveUpdateSvc;s
C:\Program Files (x86)\IObit;fs
Undetermined;ff
Advanced SystemCare Surfing Protection;ff
C:\Program Files (x86)\IObit Apps Toolbar;fs
bbmegnmpleoagolcnjnejdacakedpcgd;chr
autoclean;
emptyalltemp;
ffdefaults;
chrdefaults;

Ok Thanks
Attached the new log

No changes in Chrome, symptoms are still present

 

[TwinHeadedEagle]

Try this please

[f.van.zwol]

Sorry no succes.
The browser window is black.
No menus or screens are visible, so i can't see what is happening or what i am doing.

 

[TwinHeadedEagle]

This isn't caused by malware, probably some bug in latest version.


Try this solution

[f.van.zwol]

That's it.
Did not find this on google help myself.
A new version (without notification) which did change the startuppage and a black screen surely looked like malware to me.
But it was a bug afterall.

Thank you very much for your help. I will make a donation shortly.

 

[TwinHeadedEagle]

Thanks
