So I am not sure how I got this virus or what happened...but somehow --a virus logged into my gmail account and sent out 500 random messages.
The messages themselves are odd...they have no subject.
then it has a random link to a website with a domain ending co.cc.
Anyone know what this virus is? Importantly, how do I get rid of it?
From what you have reported, this is a one-time incident, despite the way you describe it which makes it sound like its going on continuously.
What apparently happened is that 500 messages were sent, at the same time that you were logged onto gmail on your Mac.
From that you have made the huge leap of faith that it
only happens when you are logged on , and that you have a virus on your Mac ! (congratulations, you'll be a celebrity, the only Mac with a virus (and its very rare as its only infected your Mac ! )
You use phrases like "its only doing it...,and its simply activating" which make it sound like its going on all the time, then you say it just sent one single batch of 500.
Remove all your assumptions and just state the facts, what actually happened.
Which as far as I can see from your piecemeal accounts is,
1. you found 500 sent messages in your gmail account (exactly 500? Or is that a guess?).
2. They were sent at the same time you were logged on to gmail.
Are those the only two facts?
If they are, the most likely explanation is that someone else connected to your gmail account at the same time period you were logged in, and used it to send spam. There are numerous ways this could have happened, many of them not going anywhere remotely near your computer. A virus is the least likely, by a long long
long way, probably number 1,246 out of 1,247. (and number 1,247 is that Aliens did it )
