I have a computer running Windows 10 Professional. I have Kaspersky Internet Security.
I was recently alerted to a detection of HEUR.Trojan-Downloader.Script.Generic. When I tried to resolve it, the exclamation point icon turned to a spinning circle for about a second, and then went back to the exclamation point.
KIS says that the detection was an e-mail attachment.
I use Thunderbird on my desktop, and webmail for Gmail and Outlook. As far as I can tell, I never received an e-mail from the account that it claims the detection was found in.
I never opened any unusual attachments.
When I click on "Go To File", it takes me to "My Documents" and I find no file there that could be the detected virus.
Please advise.
