Trojan Downloader

Pretty sure thats a Windows trojan you probably have sitting around in your email or was packaged in a .doc file someone sent you.

But thats not whats causing problems with your computer.

 

Run some utilities like Disk utility. Repair permissions etc. If you have a program like cocktail clean out your caches etc..

You could have too much garbage and/or you're using up all your HD space.

Check your memory too.

 

No virus for Mac! ClamXav for windows users...

I had that same "trojan" on my last mac (inside an email attachment) and did not have the symptoms you are having.
For the slow computer try resetting your PRAM memory:
1.shut down computer.
2.turn on computer.
3.press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
4.Hold the keys down until the computer restarts and you hear the startup sound for the second time.

What applications are shutting down and what are you doing when that happens?

I talked with Apple tech support today and they say there was a virus for the mac 2 years ago. All the virus did was- force the user to keep entering the network password in the user preferences. Oh NO! The fix was to keep the user preferences password locked until you wanted to modify it.

There are NO reported trojans or worms for the mac yet- according to tech support, of course I saw lots of users on this forum stating otherwise. Maybe if they called tech support Apple would resolve the issue. Until its official I don't believe it can be that bad.

ClamXav is nice to use if you sent emails to windows users. Just read their homepage:
"Today, the number of viruses actively attacking OS X users is...NONE!"


Macs Rule!

 

It's a Windows trojan.

ClamXAV doesn't detect anything that can affect OS X.

 

There are no viruses in the wild that affect Macs. No Windows application, including trojans, viruses, worms or other malware will run on a Mac, unless it's in Boot Camp or something like Parallels or VMware Fusion, which emulate Windows.
