Mac Virus Attack?

Lakers!
My Norton Anti Virus says something called Portscan blocked my vulnerability protection?
Is this some type or mac virus? Or maybe a hacker.
And I have a lot of credit card information on this computer; I only use my mac to buy stuff.
What can I do to prevent my credit card numbers from getting stolen?
 
"Lock up" your credit card info in a password protected disk image or store it in Keychain Access. Just make sure you don't store it in your login keychain.

If you want to keep information on your computer like this, then I would suggest using a DMG image that is encrypted.

Only open and mount it when you need access to this information.

And of course, put a password on your screen protector. That way, if someone steals your laptop, and they cannot log into your laptop via the screen protector, most will just simply restart the computer. When it starts, if they get by your log in password, they will still need to try to mount your DMG images, which are encrypted and password protected.

Even if they take out your HD and connect it to another computer, you DMGs are still encrypted and password protected.
 
THERE ARE NO VIRUSES on OSX.

Since there are no viruses, anti-virus cannot determine what is a virus at this time.

Damn close.:p

@Consultant, OP: read these. One of them says that adding anti-virus software to a mac just adds layers that can be exploited in effect putting your computer at more risk than before. I have NEVER had anti-virus software on a mac and have NEVER gotten a virus.
 
The warning comes back every time I turn my computer on. Or whenever I turn my wi fi on then off.

Is there any known virus called Portscan for mac?
Kinda paranoid.. I don't really save my credit card numbers or anything on the computer, but I use it to buy stuff on ebay and manage my bank accounts.
Can they still access my info?
 
Portscan = the process of port scanning. Port scanning happens all the time, especially on college campuses. It only means that someone is running port-scanning software against the IP addresses the user knows or suspects are active on the network. It's looking for an open port it can exploit in some way. I suspect it's Norton's firewall that's raising the alarm, not the anti-virus.

Basically, it's like saying "a thief is casing my house."

True, if Norton is using some other concept of a port scan, then I'm wrong.

But when I was a college prof and was on the college network on my PC, the firewall I used (Zone Alarm) constantly told me I was being scanned, and I'm sure it was true. But since my ports were locked down, I didn't care.

If you'd like to see how vulnerable you are, check out

www.grc.com

click through to ShieldsUP, and then get your machine tested. Ask to have "common ports" and "all service ports" checked. Don't bother with the other tests, because they're Windows-specific.

My Mac, for example, has its ports hidden but does respond to a ping, which is not good. I'll have to fix that.

Oh Thanks,

Your first problem is having Norton AntiVirus installed on a Mac.

+1 Norton is easily one of the worst antiviruses out there. Same with its big brother symantec. I wont even attempt to guess without scientific notation how many times either of those said a machine was clean only to scan with Nod or Kaspersky or AVG (free version) and find all kinds of "goodies"
 
WTF? I have never seen this before.

So, all of a sudden I notice this page has opened in Firefox, all on its own.

Now, I don't EVER go to porn sites and no one has used this computer other than me. My wife has possibly used it once or twice but I can guarantee she didn't go to any porn sites or any sketchy sites.

So I didn't think too much about it, just closed the window and then a few days later it popped up again! all on its own. Its done this a few times in the last couple of weeks and again last night. I'm not on sketchy websites, I'm on Macforums or Ebay, P.O.T.N. or CBC, (where I pull credit)

I don't know what could be causing it? I haven't installed anything and given my admin password. I manually checked for the OSX.RSPlug.A Trojan Horse and don't have it, I even installed and ran virus barrier X5, that didn't find anything and I quickly uninstalled it.

I just cleared all the data from Firefox and restarted. If it comes back I will try reinstalling the browser I guess.

EDIT:
Sorry, I meant to post this in its own thread. I didn't realize I was replying in this one........If any moderators want to move this, that would be great.
