Virus question

it is totally safe. yes you will have to install. but no .exe files. im pretty sure that apples do not use exe files. i have never had a prob with my comp with all the P2P file sharing i have done.

The zip will likely contain a 'dmg' which is a disk image. Your application will be sitting in there as a 'bundle' with a .app extension that you drag to where you want to run it from (usually Applications). Occasionally, it will have an 'install' icon which will install it there for you.

Aside from the 'proof of concept' Widgets of Doom or a dodgy installer of Office from the P2P networks, there hasn't been any other malware for OS X

If you're really concerned, you could have a look on versiontracker for the apps you've downloaded and check through the comments for any reviews that suggest odd behaviour after installation.

Enjoy your new software...

Mac executables are generally not in zip format, rather bin, hex, sit, .dmg, etc. No exe's to worry about unless your emulating a x86 and running some form of Windows.

Best advice, watch your sources. Don't install what you don't need if it is suspect.

Mac's can get undesirable programs running, and social engineering is still the way most computers are engineered. If you don't know where it is from or don't trust the source, then don't use it.

Macros if your running VB, Trojans (though I haven't seen any for osX), and Java can still cause problems, but it isn't likely that that has happened. You can still transmit viruses, even if your system isn't affected. For instance if you download an infected .exe and post it on your website hosted through your computer, people could still download the infected file. If you download an attachment and send it off to somebody else, you can still infect them.

Now for the bad news. Not all compressed files can be scanned well. Not all compressed viruses can be detected. Lastly, the best vector for infection is you.

In all honesty, your safe, especially if your running Norton. Peer to peer is likely safe for Mac users, though there is a lot of garbage out there on the Windows platform.

Your safe, but a healthy amount of fear is good.

If you are really worried, email the expanded program to your self through Hotmail or someother service that offers free virus check.

Look, if Symantac isn't really selling a product to you, it is likely that you don't need it.

Try this. It will check your computer for it's security level. Most PC's fail. It dosn't do a virus check. I can't find a free Mac virus check online, which means there isn't a market for it.

You can search a virus database here for OS 10 virusus. You won't find any. Part of the reason is how the OS is constructed. There is now way to reliably generate 2 simultainous buffer overflows.

Interesting. It's insisting that my port 80 is open but my sharing services have nothing checked, and my firewall isn't telling me that it's open. My router doesn't have it forwarded either... hmm, I wonder whether this is worth investigating further...

You will know if you have something to worry about, the day a virus for OS X is released, it'll make serious headlines. Relax.

Altho you're smarter than most PC users for even knowing that viruses can hide in compressed files!

It reported all my ports as closed/stealth except for PING. But most of them reported back as closed and not as stealth, which seems strange. One of the other online checks reported these as being in stealth mode. I wonder if it is getting a response (to know my ports are closed, rather than stealth, and that your 80 is open), from the router and not the computer?

EDIT: After reading Mitthrawnuruodo's post, I should probably add, if my idea is right, what kind of router I have. AEBS.

Have you updated to Tiger...? When I ran the check I got the green OK (Stealth) on ALL ports... the only open thing was ICMP Ping...

Yes. I'm on Tiger and I went into Advanced and checked all those 'stealth' boxes etc (all 3 of them basically) but it's only telling me that my ports are closed, not stealthed

EDIT: A restart (since I can't recall if I restarted my Mac after making the Advanced changes to the firewall) has resulted in me having a few ports stealthed (up from none) but port 80 still showing as open along with the PING

Great! For PCs it's an ActiveX download, so you have to use MSIE - a security risk to check for security risks? And it tells me I don't have a virus checker installed although I do. It's just not Norton anitvirus.

I think that since the programs I downloaded are .zip, they are probably PC versions and not Mac anyway!

That is not necessarily the case. I downloaded a new widget today that was in .zip format.
