My brand-new iMac keeps freezing. HELP!!

You don't need, and should not use, commercial anti-virus software on the Mac side. For Windows, use Windows anti-virus software if you consider it necessary.

LInc is correct.

If this is antivirus software installed from OS X, you do not need it!

Antivirus software running in OS X causes more issues than it solves.

Usually,,slowdowns and freezes.

I, usually, ask about this, but forgot based on what everyone else was going with your issues.

Get rid of this software. If the Antivirus software has its own uninstaller, use it to uninstall the antivirus software.

If you run Windows, install Windows antivirus on the the Windows side of things, if you must.

It seemed like CrashPlan's backup software was causing the issue, but after uninstalling the software, the problem only happend much less frequently.

There was a known issue with CrashPlan and Java 7 that required the user to patch it, but it would appear that they are in the process of rolling out a new version that is fully compatible. I'm still using Java 6 and CrashPlan 3.4.1, so I can not speak from experience on this.

CrashPlan Update 3.5.2

You may notice that CrashPlan is running leaner and meaner today. That’s because the CrashPlan team has delivered another tune-up: v3.5.2.

As usual, performance enhancements come standard. And, if you are one of those Mac users with a nifty Retina display, you also received a new, high-resolution interface. Oracle’s Java 7 is now fully supported as well.

So once you get all the bits and pieces of the older version cleaned out, you might give this one a try.

This reply is a general comment. First, perhaps you have a Mac problem and perhaps there is a CrashPlan intersection - I can't tell based on the information provided. Next, there is a lot of advise in this thread, some of which I agree with and some that is just opinion.

More information needed: 1) What version of CrashPlan? And have you called CrashPlan - the company?

My opinions:

1) Based on several years of experience, CrashPlan ( the software system ) is rock solid and to an such an extent that I occasional wonder why it is never effected by the dozens of Java updates in a Java unfriendly world. I run a CrashPlan server and have many Crashplan client backing up to it and it is amazingly stable across many versions of Mac OS - Currently 10.5 thru 10.8 clients backing up to a CrashPlan Server..... With that said, today I am hunting for a java related instability on my Mt.Lion MacPro..... So, perhaps Crashplan is having problem......

2) All new Mac users should buy AppleCare! It is the cheapest, best tech support you will ever get. Yes, sometimes their tech support procedures and request will make you work at a problem but they are good for newer users in particular. Second, if you are close enough to a AppleStore, go to the genius bar - you will learn a lot about your Mac if you are so included.

3) Oracle and Apple need to make friends and get Java 6 and Jave 7 patches out in a timely fashion.

4) Turn off Java in your web browser. But Java is generally good otherwise.

Finally, if you a sure it is CrashPlan, or Apple contends it is CrashPlan - get help there from CrashPlan, Inc. or if you have the free version of CrashPlan, uninstall and find a supported backup method. Everyone need support sometimes and free backup is not your friend. When you need your backup you are going to need help bigtime so pay a good company and you will get good help.

I may also be able to help on specifics. But you probably are best off with Apple and CrashPlan, Inc. to start.

This is a relatively old thread. Not sure why you are replying to me as I've never had a CrashPlan problem and the OP apparently didn't either as he said the problem was solved by not doing an anti-virus scan of his Bootcamp partition.
