I accidentally downloaded and opened an .htm file from an email. When I opened it, it took me to a webpage and made it look like something was loading. I realized my mistake and closed the tab, and did a system restore to 7 days ago.
When the system restore was complete I noticed that the file I downloaded was still there. I downloaded Kaspersky because I have used it in the past and am using a 30-day trial. I ran a full scan and they could not find any threats.
What, if anything, should be my next step?
