Hello! I hope someone can help me. Avast has found and removed the same malware 3 times. It is being moved to the chest but keeps returning. A screenshot of the virus is attached. I was not able to find anything online about “camoca mosim”. Most topics regarding VBS downloader are old or require me to download premium software. Any help or guidance would be appreciated! Thank you.
Hello,
this look like some random name. Can you post sha25 of the file in virus chest or send the file to Virustotal and post the link of the scan result, please?
Milos
In addition, can you please run these scans? https://forum.avast.com/index.php?topic=194892.0
Thanks for the responses! Forgive my ignorance, how do I create a “sha25” of the file? In the virus chest, I see an extract option. (Image attached of my virus chest with the options I see). Is this what you mean? I hesitated to do that just in case that is not what you meant. And then if that is the case, I then go to virustotal and scan the file, posting results here? Thanks for the help! 
As an FYI, I did “send the file” to Avast for analysis already. There wasn’t an option to send it anywhere else when you click “send for analysis” .
Here are the MalwareBytes results. There were 40 finds, 3 of them malicious. I did go ahead and quarantine. The first scan I did not include a rootkit scan so I’m scanning again. I did see the “camoca mosim” verbiage in these initial results.

Nothing in the MBAM logs indicates a VBS infection, just some PUA/PUPs. From the same instructions, can you run Farbar Recovery Scan Tool (FRST)?
As for hashing a file - In a powershell prompt (Hit the Windows Button, and type “Windows Powershell”, right click and run as Administrator).
Type the following command, exactly as written: Get-FileHash ‘C:\Windows\System32\Tasks\Camoca Masim’ -Algorithm SHA256
Edit: Rather then have you play around in powershell (not recommended), post the VirusTotal results, they will give us the hash.
Thank you for your time! That’s weird. The results before I quarantined and exported results showed 3 malicious files were found and the rest were PUPs. Are you referring to https://www.virustotal.com/? What file would I be submitting to them?
I am comfortable using powershell unless you feel this would reactivate any virus issues.
I did complete another Malwayrebytes scan with root kit selected and zero issues were found.
What file would I be submitting to them?C:\Windows\System32\Tasks\Camoca Masim
post link to scan result here
Here are the Farbar scan results - attached.
I used the link you gave me, that also matches what my avast showed but that file cannot be found, maybe because it was quarantined?

Anyway, @Sass Drake will check your attached logs when he is online
Ah - I’m blind. Malwarebytes removed the threat that Avast! is complaining about. Detected as Adware, not a VBS Downloader.

Sass Drake will need to double check your logs, but mrt.exe shouldn’t be blocked on a typical system.

Thanks so much guys for the help! It does appear that MalwareBytes got it, assuming it doesn’t come back again like it did in Avast. So I guess it’s not as harmful as an actual VBS downloader, that’s good news!
Let me know what I should do about this part in quotes below. I’m not sure what this is for. I use Spybot Search & Destroy, possibly blocking the mrt.exe file? I do recognize the HKLM from some Spybot scan results in the past.

I’ve sent this thread to Sass drake for review, not sure if he never saw it or what… Whilst you wait,
VirusTotal: C:\Users\lcoul\AppData\Roaming\751848~1\nelicil.exe
Save that to a file called “fixlist” with the TXT extension. Place the file in the same directory as the FRST executable. Open the FRST executable and press “fix”. It will run and save a new file with the results. Please upload that file here.

- fixlog.txt should be genereted and opened. Attach it your post and wait further instructions.
This file: VirusTotal: C:\Users\lcoul\AppData\Roaming\751848~1\nelicil.exe is no longer there. I made sure files were not hidden and triple checked. The 751848 nor the nelicil.exe are in this directory. Perhaps Malwarebytes got it too? Maybe I’m good to go now? Maybe there isn’t a need to have anyone else spend more time on this, unless you feel Sass drake should still take a look at it?
I truly appreciate all your help and time. THANK YOU!
