Skype online check

[Crazy_Ewok]

I'm just sitting there, working in Blender, when the Skype bubble in the corner comes up with this

Hidden/Spoiler:

And then a link here

What does this mean? I did a really quick google search and I don't think Skype does this regularly. I did read the Terms of Service and Use, but I don't remember online checks. I'm running a scan now. Is this just someone with nothing to do messing with me?

[Edit] Ok, longer search says that this is just a user trying to get me to download nasty virus junk. I'm fairly certain that that is what this was. Still, has anyone else encountered this?

Never follow links given through online chat. Never ever ever. If your virus scan doesn't turn up anything (and this should be your first check) and you don't have any symptoms of a virus (popups, sketchy processes running, etc.), then you probably don't have a virus.

Trust reputable antivirus/antimalware. Never trust chat programs.

Haha, thanks Maveritchell! I thought so, but its always good to be reminded. No chat program was ever made to scan your computer.
