I need to know how to check if i have a virus.

Okay, this is what happened: I'm on google. i click on a picture. Of a Lion. I go to the page. And then all of a sudden, the whole web page turns to something that looks like a finder window, except it's still on a Safari browser. There are folders i don't recongnize and one of them says "Trogen" and somehting was suddenly scanning my computer! Then i got a pop up that said "Serveral viruses are on your computer. You need to download virus software" or something like that (i stupidly didn't write the message down because i was freaking out) and it said something about a thing called "Hacktrack" or "hacktrap" (like i said, i didn't write down the exact word.

Anyway. It wouldn't let me leave the page until i said okay to the pop up. I couldn't even shut down the system.

I clicked okay. And nothing happened. I haven't noticed anything yet and i'm running disk utility as i type.

Was this just a joke? Is my computer in danger? Anyway, please give me some advice on what to do. And maybe a like to a virus checker.

Also, if any experts here wants the link to the website i was on, in order to check it out, or ban it, or whatever, let me know.

Macbook Pro, Mac OS X (10.5.8)

    yikes! the same thing happened to me. For example, I clicked on an article on the New York Times website and a safari window pops up that looks like a windows screen and there was a bar scanning my computer. I immediately shut down the safari window and reset everything. Now periodically I will open a regular website or click an article and another window will open. The URL first says something like, "googlesyndication.com" and then it opens a spam site. I know mac's aren't supposed to have viruses but this is highly suspect. I would also appreciate any advice!

    SlugLady: What you saw was "scareware": a sleazy advertisement designed to frighten you into buying some unscrupulous developer's anti-malware utility. There are currently NO viruses at all that can attack the Mac OS.

    You don't have a virus.
    There are no viruses for the Mac.
    You can get malware, but currently only by installing software from dubious sites. Unless you're downloading and installing truly dubious things, you're fine. If it makes you feel better run clamav. It will tell you that you don't have a virus.

    that's not true. macs do have viruses. i was told this at the macstore 6 days ago when i bought my macbook. the difference is that they have fewer users, therefore fewer viruses. as more people buy mac, there will be more viruses.

    If you can identify a Mac virus that has been spread in the wild, I'm sure we would all be very interested in hearing about it. The "there aren't that many so no one writes viruses" reasoning has been around for years. While many viruses are written to get users data and other information... there are tons of hackers out there who just take "pride" in being able to accomplish something. The fact that, to the best of our knowledge, there have not been any OS X viruses in the wild would seem to indicate that it is, in the very least, very hard to get a virus with casual use. It would definitely be a feather in the cap of a hackers hat if they were able to create a successful virus... but it simply has not yet happened.

    That statement is patently untrue and based on rumors. If there were 10 users, you'd be right, but there are nearly 100 million Mac OSX's that are living and breathing.

    The reason there are NO, let me repeat that word NO, viruses on the Mac are:

    1. Mac OSX is built on UNIX, which has a security architecture at its core.
    2. Apple browsers (Safari, Firefox, etc) are not a part of the operating system, but are separate programs. This keeps web based malware from invading the operating system.
    3. OSX lacks a registry, one of the most critical areas of attack in Windows
    4. To get administrative access, a virus needs your password. It's not 100% effective if the user decides to always enter your password without knowing what program is trying to add to your OSX, but a smart user would never see it.

    An anti-virus program pulls system resources and memory. In the world of real medicine, the risks do not outweigh the benefits, because in this case, there are no viruses. It's a waste of money and your computer's performance to gain no benefit whatsoever.

    So solarrae, I would suggest you get some information before posting such incorrect data. There are NO viruses on the Mac.

    +*Apple browsers (Safari, Firefox, etc) are not a part of the operating system, but are separate programs. This keeps web based malware from invading the operating system.*+

    Just this simple step helps to avoid nearly all viruses in Windows as well (at least those that you might get simply by visiting malicious websites). Unfortunately, apart from the tech community (and friends of the tech community who we support)... the vast majority of users still use Internet Explorer which leaves them open to all of the ActiveX nasties.

    JoeyR...I think Windows would be a much better product if Microsoft could start from the ground up, rebuilding the whole operating system.

    I'm not sure I'd be a Mac user if OSX was built on System 9. That's a scary thought.
