Malware-gen??

So Avast locked up Malware-gen into the threat chest and I absolutely noticed nothing wrong with my laptop and it said on February 23rd is when it locked up the threat and I checked the browsing history on Chrome to see if maybe one of my family members accidentally pressed a link or went to a website and nothing was downloaded and only Pinterest was on the search history which a family member likes to go on there and they never pressed anything or downloaded anything and Malwarebytes and Adwcleaner never picked it up, my computer is clean since I let Avast delete the file but how did it get on there and was it possibly a false positive??

and was it possibly a false positive??
Impossible to answer from the info given

Upload and check file at www.virustotal.com

And detection/false positive issues should be posted in Viruses and Worms section

I meant to post this in Viruses and Worms, sorry about that! And I wish I would’ve but I let Avast delete it without thinking

There is no rush to delete files in chest … files moved to chest (quarantine) can not harm your computer

Thank you for informing me on that! And in the notifications I checked the alert for it and the file that was infected with malware-gen and put in the chest was msl.dll
