Need Help w/.RAR Downloads + uTorrent doesn't open

I can't hep you with RAR video files (I never knew there was such a thing), and your software seems fine except you have missed some useful plug-ins:

Flip4Mac WMV Player from http://www.telestream.net/flip4mac-wmv/overview.htm (Windows Media Player for the Mac is no longer supported, even by Microsoft)

Perian from http://perian.org/

You should read this support page http://perian.org/#support in case you need to delete older codecs.

The latest version of Adobe FlashPlayer can be obtained from here:

(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.

You should first uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):

and also that you follow the instructions closely, such as closing ALL applications first before installing. You must also carry out a permission repair after installing anything from Adobe.

But beware of downloading from torrent sites:

Although any content that you download has the possibility of containing malicious software, practising a bit of care will generally keep you free from the consequences of anything like the DNSChanger trojan.

1. Avoid going to suspect and untrusted Web sites, especially p'orn'ography sites.

2. Check out what you are downloading. Mac OS X asks you for you administrator password to install applications for a reason! Only download media and applications from well-known and trusted Web sites. If you think you may have downloaded suspicious files, read the installer packages and make sure they are legit. If you cannot determine if the program you downloaded is infected, do a quick Internet search and see if any other users reported issues after installing a particular program.

3. Use an antivirus program like ClamXav. If you are in the habit of downloading a lot of media and other files, it may be well worth your while to run those files through an AV application.

4. Use Mac OS X's built-in Firewalls and other security features.

5. Stop using LimeWire. LimeWire (and other peer-to-peer sharing applications) are hotbeds of potential software issues waiting to happen to your Mac. Everything from changing permissions to downloading trojans and other malicious software can be acquired from using these applications. Similar risks apply to using Facebook, Twitter, YouTube and similar sites which are prone to malicious hacking: http://news.bbc.co.uk/1/hi/technology/8420233.stm

6. Resist the temptation to download pirated software. After the release of iWork '09 earlier this year, a Trojan was discovered circulating in pirated copies of Apple's productivity suite of applications (as well as pirated copies of Adobe's Photoshop CS4). Security professionals now believe that the botnet (from iServices) has become active. Although the potential damage range is projected to be minimal, an estimated 20,000 copies of the Trojan have been downloaded. SecureMac offer a simple and free tool for the removal of the iBotNet Trojan available here:
