SERIOUS VIRUS! I HAD IT & JUST FIXED IT BUT I NEED 1 QUESTION ANSWERED! PLEASE?!

Hay there my sweet peas. This is very important! I've had a serious damn virus so this is a warning to yall & also a question too. I'm really needing my little computer savvy sweeties right now! Ok, so the thing is, there's this God awful (that's not a bad word is it?) virus that goes by the name of "security tools" it pops up and will stop you from accessing anything. I was online as it happened and suddenly it wouldn't allow me to access anything and it would not stop popping up saying I had a virus & needed to purchase this "security tools" software. I freaked & so did the bf. We ran virus scans and all. We called my supposed computer pro friend person & he gave me a nervous break down saying that my computer was ruined and all this shit. I cried and this started at 4 PM. It's now almost 5 AM and I've been working on it ever since. So I followed instructions from a much more trusted friend & an online site that's for removing this specifc virus. I ran the scan it came back that no malicious stuff was detected. I ran again. Nothing. I was terrified to even turn on my computer because the self proclaimed computer pro led me to believe that it's be screwed. I finally turned it on & followed the instructions like I said. Everything went perfect.It was like nothing ever happened after the scan. I didn't even have to remove anything. There was one problem though, my internet would not connect. I have internet explorer. I finally figured it all out by going to tools, clicking internet options and all this & voila! It was like brand new. Got a connection in less than 9 seconds.

   I have one question and I'm so grateful to anyone who takes the time to read this and help me. I know I'm not very good with explaining or computer stuff so truly, I'm grateful! Ok, my question is do you think I'm safe? I mean is the virus lurking around somewhere?

 The thing is, my computer is very expensive. It's the first one I've ever owned myself & the bf bought it for me last christmas he spent over 9000 dollars on it & he will be pretty freaked when he finds out I turned it on and worked on it. I truly think it's fine. I mean it's working great, but he was told my the self proclaimed computer pro that it'd be ruined if it was even turned on & we'd lose everything so I need serious help. I'm sure he'll freak when he finds out I turned it on & he'll want to be 100% sure that I done it correctly and nothing is wrong. I will do anything, just please any suggestions would be more than helpful. Is there anything I may need to do or do you think I've got it all under control?

Love you sweeties so much! Please though, any advice?
