How true can this be? I am at a school that uses Windows pc's 100%. I am the only person in the entire school system that uses an iBook, personal iBook as I refuse to use the laptops at school. A tech came into my room this morning inquiring if I was iBook. I answered yes, and he asked me to disconnect from the network as my laptop was broadcasting a network Trojan virus. I did as was told and ran Virex on my system, came out clean. Virex has the current update. This has me wondering since I was working on my laptop last night, it froze. I couldn't reset, force quit, nada! I had to remove the battery to shut down. This had never happened before. It was the first major freeze on my laptop in two years. Then what happens? I am told that I am broadcasting a virus the following day. Coincedence? Is there any other way I can check to see if there is a trojan on my computer? How could I have gotten one? The only software I downloaded recently were yesterdays updates through Apple. Any suggestions? Oh, when the freeze occurred, I wasn't even connected to the internet. I was working on iPhoto creating a slideshow.

Your tech guy should get another job, period. It's definitely NOT a virus. There is no known virus to date on Mac OS X, and in addition to that, even if it was real one, it wouldn't affect any PC, as it would be Mac specific.

What he saw was your iBook broadcasting packets (problably rendez-vous). That's all. Nothing to worry about.

About your freeze, there is a known bug in Mac OS X 10.3 which causes freeze of the whole system (for a few minutes sometimes). See the long thread in the Mac OS X forum. It hasn't been fixed so far by Apple. Hopefully soon... fingers crossed.

try the software, or the osX, or the networking forums.

not the hardware specific ibook forum.

The Macs broadcast on port 445 for SMB related stuff. I've seen this show up on firewalls. This occurs on a regular basis. On the PC side, there are PC viruses that broadcast on this port. The guy likely saw this and assumed you were broadcasting one of these PC viruses. It caught me off-guard the first time I saw it, as I thought some of the PCs had viruses, but it was the Macs.


and yes, this is the wrong forum.
