Windows 10: McBuilder.exe - virus or real?

Hi, I scanned my computer with Eset Online Scanner and it found this:

C:\Windows\WinSxS\amd64_microsoft-windows-muicachebuilder_31bf3856ad364e35_10.0.17134.165_none_fba14b370afb4d95\mcbuilder.exe pravdepodobne neznámy CRYPT.COM vírus zmazaný

*probable Crypto.com virus* in english


I had 4 mcbuilder.exe files before,now I have 3. One is 3,041 bytes, another 2,929 bytes, another 91,136 bytes.

Fourth one was deleted due to Eset and marked as probable CRYPT.COM virus.

I asked on eset forum and they mentioned something like they have only 2 mcbuilder.exe files in their winSxS folder. I had 4.

There was a big update rolled out a few days ago, could it be that it added another 2 mcbuilder.exe (so there were 4 instead of 2) and Eset falsely marked it as virus?

I have win 10.


Could anyone verify this for me please?thanks

:)

Malware tprdpw64.exe after installing 7zip

Thank you for the reply and the suggestions. However neither link provided a working solution. I followed each set of instructions step by step, to the T, but the viruses are still there.

I killed the processes with Rkill as instructed, and it found and ended the malware process `tprdpw64.exe`. It, however, did nothing
about the adware `svcvmx` & `svcvmx client` processes. After doing so I downloaded and installed Zemana, as instructed, and let it do a full system scan. Might I add that this took over
10 hours to complete, as I have 1,396,541 files on my PC, so this whole thing wasted nearly half a day of my time with no results.

Zemana detected the malware virus `tprdpw64.exe` located at "C:\WINDOWS\System32\tprdpw64.exe"
(among other, smaller "threats"), and labeled it as malware. After it finished the scan, it said it has placed all files into quarantine, including `tprdpw64.exe`.
However, when checking the quarantine list `tprdpw64.exe` is
not listed. I then decided to have Zemana remove the files in the
quarantine list from my system and then rebooted my PC. It removed them all successfully, except for `tprdpw64.exe`
which is still on my system, and still runs (I can still see it in task manager after rebooting). So the 10+ hours of waiting were all for nothing.

I then used Zemana's "drag-and-drop" feature to re-scan just `tprdpw64.exe`
(in order to not have to wait 10+ hours again). It scanned it, and now says the file is not a threat (but it clearly is).

I then proceeded to step 2, using AdwCleaner to remove the adware. This did not work in the slightest. AdwCleaner did not detect the adware virus at all, and thus did nothing about it. I still cannot remove the viruses manually, either. However for some
reason, the adware `svcvmx` & `svcvmx client` processes no longer seem to run (my PC has been on for about an hour, and the processes
have yet to startup). However, even so the files are still on my file system and would like to delete them.

EDIT

I have just searched my registry, looking for any possible signs of tprdpw64 being listed, and there was nothing there.

 

One of my exe files is blocked in Windows but there is no explanation why

Hi Frank B.,

Corrupt registry settings or some third party product (or virus) can change the default configuration for running EXE files. This may lead to failed operation when you try to run EXE files. Having said that, you may want to turn off the
Controlled folder access in Windows Defender and see if it makes any difference. You can follow the steps below:

• Open Windows Defender Security Center.
  
• Select Virus & threat protection.
  
• Click Virus & threat protection settings.
• Scroll down to Mange Controlled folder access then toggle it
  Off.

If you have additional questions, or if the issue persists after the troubleshooting steps above, please let me know by replying to this thread. This way, I'll get notified and respond back to you as soon as I can.
