I recieved a reply to one of my craigslist for sale posts today. They asked if it was my best price and mentioned my actual item I was selling. I've always been good at being careful not to open attachments from others, "even from those I know if it looks funny" but today I was fooled when the attachment showed up as if it were only a photo. It displayed the typical box with view slide show or download as zip in the upper left corner before their message. When I hover over the download box cursor it briefly says, Download rn.jpeg (2.4 KB) Needless to say all I get is a white photo so I'm sure it's not good nor really a photo.

How will I know how bad or how serious I was compromised? I'm even afraid to sign into my account as I don't know if they are recording keystrokes and will steal it.

I ran full system scan with 360 Norton then downloaded and ran free version of Malwarebytes Anti- Malware. Both found nothing.

Thank You Sincerely
