I accepted a friendship from some I thought I knew then I received a message in messenger telling I was a winner a I needed to register in 15 min but at the top it showed connecting in red letters. My computer started to slow down to where I was not able to open any pages. I instantly did a full scan virus and got into the facebook acct and blocked the new friendship and noticed there were two and I only accepted 1. Turned off the computer and turned it back on and the computer has been working almost as before. Also when I opened EDGE the page was changed. My question is could there be a virus, trojen or etc. still on the computer and what else can I do to make sure it is gone. Thank you ! Tanya
