After Windows (10) update, my desktop PC runs significantly slow

[Luminous]

Hello,

About a week ago and after the Windows 10 update ^{(I already had Windows 10 previously)} my desktop was very slow, and only whatever had to do with the programs and the Windows. Using the Internet was fine. It took half an hour for my desktop to completely start up/shut down each time. A couple of time it did shut down faster, but only these one/two times. After about 1 to 2 minutes at the starting up process, the screen went completely black for about 30 seconds or so and only after that black screen disappeared, only then I was able to run anything in my PC (application or to work with Windows), but again all operations were very slow.

I was waiting for 5 minutes or more for Windows to load the control panel or any other program! Exactly after the Windows update, I also noticed that the Kaspersky icon appeared again on my desktop, like when we just install a program. I tried to run Malwarebytes from the arrow at the system tray, but nothing happened when I clicked the icon there. I went for a walk with my dog and after half an hour Malwarebytes still didn't launch, nothing happened. Then I went to run Malwarebytes from the installed programs, and a window from Windows opened ^{asking me if I give my permission for this program to allow to make changes in my computer} just like when we are about to install a new program … :-o

I did run a scan both with Kaspersky Internet Security and with Malwarebytes but they didn't find any threat.

Searching for solutions online I came upon a thread somewhere with the following tip to make our Windows much faster:

https://m.reddit.com/r/Windows10/comments/3fm7m8/windows_10_is_very_laggy_and_slow_after_the_update/

After I did that, my desktop run again as normal and perhaps a little faster. But lately, the past two-three days, I have noticed that when I am starting up the chrome browser, it starts from a blank screen and after 2-3 seconds loads gradually the page (I have set it to load the apps page). So, I think that the problem has not been solved, but rather postponed.

Also, on the Internet, when I am clicking on something, sometimes there’s a significant lag before I can continue with the selected action.

I did run and saved the results from the Event Viewer from Windows 10 and it found 3 critical errors and many other problems, but there’s not any relation to any file/program so I don’t know where to search.

Attached are also the results from the Farbar Recovery Scan Tool.

Many thanks in advance people! <3

STEP 01
RKill is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes so that your normal security software can then run and clean your computer of infections.
When RKill runs, it will kill malware processes and then removes incorrect executable associations and fixes policies
that stop us from using certain tools. When finished it will display a log file that shows the processes that were
terminated while the program was running.

As RKill only terminates a program's running process and does not delete any files, after running it, you should not reboot
your computer as any malware processes that are configured to start automatically will just be started again.
Instead, after running RKill, you should immediately scan your computer using the requested scans I've included.

Please download Rkill by Grinler from one of the links below and save it to your desktop.

Link 1 | Link 2

• On Windows XP Double-click on the Rkill desktop icon to run the tool.
• On Windows Vista/Windows 7 or 8, right-click on the Rkill desktop icon and select Run As Administrator
• A black DOS box will briefly flash and then disappear, this is normal and indicates the tool ran successfully.
• If not, delete the file, then download and use the one provided in Link 2.
• If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
• If the tool does not run from any of the links provided, please let me know.
• Do not reboot the computer; you will need to run the application again.

 

STEP 02

Please run a Threat Scan with MBAM. If you're unable to run or complete the scan as shown below, please see the following:
MBAM Clean Removal Process 2x
When reinstalling the program, please try the latest version.

Right click and choose "Run as administrator" to open Malwarebytes Anti-Malware and from the Dashboard please Check for Updates by clicking the Update Now... link
Open up Malwarebytes > Settings > Detection and Protection > Enable Scan for rootkit and Under Non Malware Protection set both PUP and PUM to Treat detections as malware.
Click on the SCAN button and run a Threat Scan with Malwarebytes Anti-Malware by clicking the Scan Now>> button.
Once completed please click on the History > Application Logs and find your scan log and open it and then click on the "copy to clipboard" button and post back the results on your next reply.
