Mac OS X Virus???

Unread postby mnorton » Sun Apr 10, 2011 6:03 pm

hi,

I have a weird situation with my Finder. It works fine for a while and then applications stop working. If I select Firefox or itunes from the dock. The icons bounce and never launch. I can't see my istat to tell me if there is a CPU hog. I opened a terminal to use ps -ef and this won't respond either when the situation occurs.

I believe it is a virus. McAffee found nothing. Any ideas on what to do? This started happening recently. I think it occurred when my son downloaded minecraft. I think it was a trojan horse.

Whatever it was. What can I do to get my imac back to health? I can reboot my machine and it's useable. The slowly the applications stop responding. I can't launch anything and I can't quit any application.

Any ideas?

More likely: a failing hard drive or some other glitch. Before you do anything else, I recommend that you boot the computer from an OS X installation disk and make a full backup to an external drive using Apple's Disk Utility. At a bare minimum, copy over any important personal files, software license information, etc. Then you can try to use Disk Utility's repair routines on the internal drive. After that, you can try a utility like Onyx to clear various system caches, etc. to see if that will help.

Depending on the non-page memory characteristics of finder, it could also be a bad memory.

Techtool for the mac can do both memory and hd testing. Backing up is a good idea, then running the tests is another.

for a quick/easy test, the mac's restore dvd set (usually disc 1) comes w/ hardware diagnostics

insert dvd, reboot, keep "D" pressed after the start-up sound, and go for the "extended test"
