what is this malware?

So I have tried downloading a file maybe 10 times and I never found it in the download folder. I finally figured out that the files were quarantined by Comodo because of “malware@#93slvthtaw2s”. It would have been nice if there was prompt before this happened and a link so I can read up on the treat and make a decision on how to proceed. I tried to look up malware@#93slvthtaw2s and did not find anything indicating that this actually exists. What is going on and how can I restore one of the downloaded files?

To get alerts disable Don’t show antivirus alerts.

The Quarantine folder can be accessed from General Tasks. To get to General Tasks look for the green arrow and the word Tasks towards the upper right corner of the main screen; when found click on it.
