WinThruster: Potentially Infected PC

Hello everyone,

I'm reaching out for your help because my computer is dying...

A few weeks ago, my computer started acting up, wouldn't boot, black screens, etc...

So I decided to try resetting it to factory settings, or at least I thought so, because when my computer "resurrected," the memory was completely full and I had to delete files before adding any.

For a few days now, it seems infected, very slow, black screen at times,...

I ran an Avast scan: nothing alarming
I downloaded WinThruster: detected more than 200 errors including a Trojan but only 25 were fixed because the software isn't free.
This morning, when I turned on my computer, I noticed it's lagging, so I decided to consult Google once more and downloaded RogueKiller but I couldn't launch the setup.

Moreover, I can no longer launch Avast, CCleaner, or any other applications on my computer. At startup, several error messages appear regarding .exe files.

Additionally, I manage to access the control panel but there's no response when I click on uninstall a program.

Could someone kindly give me some leads?

Thank you

Emma

Configuration: Windows / Chrome 63.0.3239.84

Hello,

By the way... I want to mention that the new versions of Avast frequently cause the error 0xc0000005.

Wishing you an excellent evening,

Hi,

WinThruster is useless, read: https://www.malekal.com/logiciels-nettoyage-windows/

Uninstall it.

Perform a cleanup with Malwarebytes - Malwarebytes Anti-Malware free version tutorial

then:

Follow the FRST tutorial. ( take the time to read carefully - everything is well explained ).

Download and run the FRST scan,
Wait for the scan to finish, a message will indicate that the analysis is complete.

Three FRST reports will be generated:
  • FRST.txt
  • Shortcut.txt
  • Additionnal.txt


Send these 3 reports to the site https://pjjoint.malekal.com/ to share them.
In return, provide the 3 pjjoint links leading to the reports here in a new response so that we can review them.

Thank you for your quick response!
I'm already stuck at step 1. I'm unable to click on uninstall a program, so I can't temporarily uninstall WinThruster.
On the other hand, when I try to launch the Malwarebytes setup, the following error message appears (in a new small window titled mbam.exe - Application Error): The application failed to start correctly (0xc0000005).
Click OK to close the application.

Thank you very much for your help!

It should be noted that this analysis was launched in safe mode because the PC shut down and the screen went black after attempting to turn it on three times.

Just for your information, I forgot to mention in my first post that the USB devices are no longer recognized by my PC at all.

Not infected

You have programs that were installed at the time of purchase or installed later that are not necessarily useful.
They clutter Windows and can slow it down.
You can therefore uninstall them.
Go to Control Panel
then Programs and Features.
Uninstall:

CCleaner
Dropbox
Emsisoft Anti-Malware
WildTangent Games App
WinThruster


PS: CCleaner is not really useful, even though it is recommended everywhere.
Disable CCleaner's monitoring, unnecessary, it starts up with Windows and slows it down with its incessant cleanings, see: https://www.malekal.com/supprimer-ccleaner-demarrage-windows/

Here is the correction to be made with FRST. You can use this explanatory note with screenshots.
Restart FRST then on your keyboard press the CTRL + Y key.
Notepad will open, copy/paste this.

Thank you!

I will restart the PC and check its effectiveness.
I will also try to uninstall unnecessary programs after the restart as it is currently impossible.

Thank you!

After restarting, you have to wait, wait, wait some more...
When the session finally opens, the slightest action leads to a new small window titled Microsoft Windows that informs you that the application is taking an incredibly long time to respond but that you can still wait.
I decide to restart the PC, and since then, I can no longer open the Windows session after entering my password. The welcome message is there, but nothing happens.
I have access to Windows in safe mode. Still unable to uninstall programs.
USB devices are still not detected.

ok test by uninstalling Avast! to see.

Install "Real Temp" or "Coretemp" to monitor the temperature of the computer.
See how high the temperature rises during use. It should not exceed 60 degrees Celsius. If possible, attach a screenshot of the software to the message.

First, check the hard drive: How to check the health of the hard drive
For example with CrystalDiskInfo.

Open the task manager
In the bottom left, click on show all processes/details, if present.
Click on the Processes tab.
(If you are on Windows 7: Click at the bottom on "show all processes of all users").
Click on the CPU/Processor column to sort processes by CPU usage.
Provide screenshots of the task manager.

Thanks again!
I will do all that when he agrees to turn back on...
This afternoon I still have the welcome message but the session won't open!
As for uninstalling Avast, it's impossible! There's no way to click on uninstall a program...

The PC crashes again when I try to uninstall a program, launch a program (e.g. Avast to uninstall it), or when I want to type Task Manager in the start menu.
Ctrl+Alt+Delete doesn't do anything either.
I managed to run CrystalDiskInfo in safe mode, everything seems fine. The temperature is also good. I also ordered a disk check at startup by typing the command in CMD, the disk is clean.

Perform a checkdisk via the command line.
You need to enter the following command in an elevated command prompt:
chkdsk c: /R /F

This will prompt you to perform the analysis on Windows restart, accept.


And if it continues to crash, reinstall Windows 7 and see how it behaves.

Hello, this is what I meant by "I ordered a disk check at startup. So that's done too.
The response was:
checking the file system on c:
The file system type is NTFS.
The volume is clean.
I have photos of the results from Crystaldisk and the execution of chkdsk but I don't know how to attach them to my message here.
Thanks again and again for your help!

On another note, I entered the task manager in safe mode and found a bunch of things ending with .exe, here is the list:

AppleChromedav
Apsdaemon
(lots of) chrome
cmd
conhost
(two) csrss
ctfmon
explorer
icloudservices
Isass
Ism
System idle process
secd
services
smss
(lots of) svchost
system
taskmgr
wininit
winlogon


All of this with:
