T-bone, I just got two of those 'danger' PMs also, from that dominic and liasanne, claiming to be members, along with that computer warning, etc....I checked the member lists, and they aren't on there.....
DO NOT open these...Some time ago, I had one of those things sent me E-mail, claiming that I had been exposed to that virus that was masquerading as something else, and to go to this site to get protection....Well, dumbass me, I did, and THAT gave me a virus that I had to buy a REAL protection program for $40 to eradicate, since McAffee couldn't....So now I have 2 protection programs.
The one I bought, by the way was Stopzilla, And I really like it....It does a real good job keeping me virus-free.
