I clicked a link in a gmail message, and arrived at a page that looks like a news site. I clicked a similar link in the next gmail message, and arrived at a page that warns that this is an "attack page": https://docs.google.com/open?id=0B-mMfXyy8lylSkZTY2hNZG8zNUk

Now, I am sure that the first link I clicked was sent to me from the same email address, so I already entered an 'attack page'. How can I check if my computer has been attacked?

What operating system are you using? Also, do you use any antivirus software? – Anderson Green Dec 25 '12 at 22:01
    
I have Ubuntu 12.04, with no anti-virus. But the "attack-page" speaks not only about viruses but all sorts of other attacks... – Erel Segal-Halevi Dec 26 '12 at 9:03
    
What was the first link you clicked? – Anderson Green Dec 26 '12 at 20:30

I got the emails from the same person, one after the other. That person told me that his computer was hijacked. So, I conclude that the same evil source sent the two emails. – Erel Segal-Halevi Dec 29 '12 at 17:19

If you have an anti-virus that didn't flag anything, chances are you are fine. Refresh the virus definitions and run a "full" scan to make sure.

If you are running an Linux OS like Ubuntu, I'd bet a month's salary that, unless you gave an attack site personal information, nothing happened and you can safely forget it happened.

Worse case is that the link in the email contained a code that let the attack site know that your email address is valid. Just be careful about phishing attacks in the future. I personally never click a link in an email from a financial institution, I type the address in manually--for example if paypal tells me I owe them money, i type in www.paypal.com instead of clicking on a link because there are some awfully good phishing emails.
