Now I run Linux and yes my system is slow because I run it on old discarded hardware that is still perfectly good (just not good enough for Windows). Vulnerable? Hardly.
I checked their DNS and the IP goes to 22.214.171.124 with port 80 and 21 open. I didn't waste too much time as it is obviously spam and probably malware.
Just curious if this is common? I've been using Skype for as long as it's been out and this is the first for me."
