Hidden malware

Hi, 

all of this started when I downloaded a program (didn't pirate, program was free) but I downloaded it from an apparently fishy website and I got some viruses. So I got rid of them, everything fine, and then I notice that System Interruptions was running on high CPU usage (up to 90%) until I opened Task Manager, and I know that because I can see that it is running high for a split second and then it instantly goes down, my room also sounded like a busy airport sometimes. I try several anti-malware, virus, etc. programs, nothing finds anything, not in rootkits, anywhere. and this continues to go on, and then RAM usage started going up to 74% while browsing Google, and I have 16GBs. I couldn't find a solution to this, so I said that I don't care and did a factory reset (deleted all my folders and reinstalled Windows). When it finishes, I am happy that I will finally be free from the panaroid me and stop checking Task Manager, and here it is again, it goes up to 90% on CPU, and goes down instantly. RAM is kinda fine, running 30% with barely anything running in the background, so I hope that it is fine. I used anti-malware programs again, and nothing. 

All I really want to know, if there is an actual virus/malware/something on my computer, so if anyone here could check for me, because I'm really paranoid the last few days.

Hi,  @vezun

My name is Maurice. I will be helping and guiding you, going forward on this case.

Please follow my directions as we go along.  Please do not do any changes on your own without first checking with me.

If you will be away for more than 3 consecutive days,  do try to let me know ahead of time, as much as possible.

 

Please only just attach   all report files, etc  that I ask for as we go along.

The initial display on Task Manager needs to be discounted.  You need to allow it a few seconds to settle in.

See this thread about exactly this same behavior   

 

NOTE:  Task Manager is not an ideal mechanism  to judge about a suspected "infection".

Task Manager is not a good way to check for infection.   We can use a number of security tools & programs to search for and find a infection.

Task Manager display on the first few seconds ought to be ignored.  Wait a minute or two for the displayed lines to settle down.

.

You report having done a factory restore.   That would have got a clean new Windows installation, without malware.   But also without Malwarebytes for Windows Premium   ( if you have a license for Premium).   You are running the Free Malwarebytes.

Malwarebytes found no malware.

Skenované objekty: 287577
Zjištěné hrozby: 0

 

Scanned objects: 287577

and Malwarebytes AdwCleaner 7.4.2.0  found no adwares / no  P U P.

Which security programs have you also run ?    Please advise.

 

This pc has Kaspersky Total Security  but is reported to be disabled.  Any idea as to why that may be so ?

 

We can run a few known security tools to further check this system for potential malware / viruses.

I would suggest a free scan with the ESET Online Scanner
Go to https://www.eset.com/us/home/online-scanner/

Look on the right side of the page.  Click Scan Now
It will start a download of "esetonlinescanner_enu.exe"
Save the file to your system, such as the Downloads folder, or else to the Desktop.

Go to the saved file, and double click it to get it started.
When presented with the initial ESET options, click on "Computer Scan".

Next, when prompted by Windows, allow it to start by clicking Yes

When prompted for scan type, Click on Full scan
Click on the radio selection "Enable ESET to detect and quarantine potentially unwanted applications"   and click on Start scan button.

Have patience.  The entire process may take an hour or more. There is an initial update download.
There is a progress window display.
You should ignore all prompts to get the ESET antivirus software program.   ( e.g.  their standard program).   You do not need to buy or get or install anything else.

When the scan is completed, if something was found, it will show a screen with the number of detected items.  If so, click the button marked “View detected results”.

Click The blue “Save scan log” to save the log.

If something was removed and you know it is a false finding, you may click on the blue ”Restore cleaned files”  ( in blue, at bottom).

Press Continue when all done.  You should click to off the offer for “periodic scanning”.
