3 Forms of TR/Dropper.MSIL in Malwarebytes, am I still infected?

[Hefirb]

I was doing a scan with Malwarebytes today and during the scan I got 3 beeps from Avira which found 3 forms of TR/Dropper.MSIL in the Malwarebytes folder and quickly quarantined it.

After the MB scan was completed and came back clean, Avira also detected a suspicious file in the Roaming folder called sp_data.sys and quarantined it too. I was shocked and I deleted all the files in the quarantine.

I did full scan with Avira  afterwards and it found TR/Dropper.MSIL.vvhoh, one of the 3 viruses that was previously found in the Malwarebytes directory. The virus Avira found while doing a full scan was found in the recycle bin, which makes sense because one of those shortlink ad websites automatically downloaded an infected .zip file claiming to be an update for Adobe. I deleted that file as soon as it was automatically downloaded. That file has been quarantined and deleted. Other than that, Avira came back clean. However, I'm still concerned and confused about the viruses found in the Malwarebytes directory while during a MB scan. Once I completed the full scan with Avira, I did another MB scan and it came back clean again. I'm not sure if I have cleansed my computer or it is still infected now, so here I am. 

NOTE: This only happened today and is the first time so I'm doubting that it's a false positive, especially when I found 3 forms of the same virus. The only explanation for this is that I spent the past 2 days re-downloading my music library and also scanned each file or archive on Virustotal to make sure it was safe. My only guess is that it was all those shortlink ad websites (ie. adf.ly) that I had to go through to get the download link for the actual songs even though I took all the precautions such as having Adblock, Avira's Browser Safety, etc. Still, it's eye-opening to see just how sophisticated this infection seems to be.

Overall looks good. No obvious signs of an infection.

How is the computer running now?

 

[Hefirb]

There was never any problems at all. I didn't notice anything suspicious. My computer was running fine before and is running fine now still so it was concerning when Avira's real-time protection found those 3 trojans and a suspicious file. Am I ok now?  Does everything look fine and whatever trojans were lurking around are completely removed?

All looks good @Hefirb

Your computer looks to be clean at this time.

Take care and stay safe out there

Ron
