There are no viruses for Mac OS X, so there was nothing to worry about with that toolbar. But if you really uninstalled it, it wouldn't still be there. Where did you install it, and what program is it supposed to work with? Have you done a Spotlight search to find any file with the names vuze, or anything else in the name of the toolbar?
It isn't a myth that Mac OS X has no viruses. File sharing doesn't matter, there are no viruses. Windows viruses are another thing entirely. If you're using Windows and sending or receiving files and email attachements to/from those users, then it's possible to spread a Windows virus.
If you didn't follow the directions to uninstall Vuze, then it's still there. If you want to remove the Vuze toolbar for Safari, just go to Finder and click on Applications, then Toolbars, then Vuze. In that folder, double click on "uninstall".
You might need to provide the administrator password to complete the process.
No viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions.
It is possible, however, to pass on a Windows virus to another Windows user, for example through an email attachment. To prevent this all you need is the free anti-virus utility ClamXav, which you can download from:
However, the appearance of Trojans and other malware that can possibly infect a Mac seems to be growing, but is a completely different issue to viruses.
If you allow a Trojan to be installed, the user's DNS records can be modified, redirecting incoming internet traffic through the attacker's servers, where it can be hijacked and injected with malicious websites and pornographic advertisements. The trojan also installs a watchdog process that ensures the victim's (that's you!) DNS records stay modified on a minute-by-minute basis.
You can read more about how, for example, the OSX/DNSChanger Trojan works here:
SecureMac has introduced a free Trojan Detection Tool for Mac OS X. It's available here:
The DNSChanger Removal Tool detects and removes spyware targeting Mac OS X and allows users to check to see if the trojan has been installed on their computer; if it has, the software helps to identify and remove the offending file. After a system reboot, the users' DNS records will be repaired.
(Note that a 30 day trial version of MacScan can be downloaded free of charge from:
and this can perform a complete scan of your entire hard disk. After 30 days free trial the cost is $29.99. The full version permits you to scan selected files and folders only, as well as the entire hard disk. It will detect (and delete if you ask it to) all 'tracker cookies' that switch you to web sites you did not want to go to.)
A white paper has recently been published on the subject of Trojans by SubRosaSoft, available here:
Also, beware of MacSweeper:
MacSweeper is malware that misleads users by exaggerating reports about spyware, adware or viruses on their computer. It is the first known "rogue" application for the Mac OS X operating system. The software was discovered by F-Secure, a Finland based computer security software company on January 17, 2008
On June 23, 2008 this news reached Mac users:

The MacScan application can be downloaded from here:
You can download a 30 day trail copy which enables you to do a full scan of your hard disk. After that it costs $29.95.
More on Trojans on the Mac here:
This was published on July 25, 2008:
Attack code that exploits flaws in the net's addressing system are starting to circulate online, say security experts.
The code could be a boon to phishing gangs who redirect web users to fake bank sites and steal login details.
In light of the news net firms are being urged to apply a fix for the loop-hole before attacks by hi-tech criminals become widespread.
Net security groups say there is anecdotal evidence that small scale attacks are already happening.

A further development was the Koobface malware that can be picked up from Facebook (already a notorious site for malware, like many other 'social networking' sites), as reported here on December 9, 2008:
You can keep up to date, particularly about malware present in some downloadable pirated software, at the Securemac site:
There may be other ways of guarding against Trojans, viruses and general malware affecting the Mac, and alternatives will probably appear in the future. In the meantime the advice is: be careful where you go on the web and what you download!
If you think you may have acquired a Trojan, and you know its name, you can also locate it via the Terminal:
As to the recent 'Conficker furore' affecting Intel-powered computers, MacWorld recently had this to say:
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 *********** 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.
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:
f you want to remove the Vuze toolbar for Safari, just go to Finder and click on Applications, then Toolbars, then Vuze. In that folder, double click on "uninstall".
You might need to provide the administrator password to complete the process.
yes, that would be entirely helpfull! i have the same problem! I go to my applications folder, and I find no toolbars folder. Furthermore, when I search my hardrrive for Vuze, toolbar, or similar keywords, I get nothing. That beings because I moved them all to the trash, and deleted them. My problem is that I still have a toolbar in Safari. Yet there's no trace of this program that I can find.
Hey man, I had exactly the same problem except I deleted the toolbars folder and then discovered how to delete it after I did that, lol stupid me !!! any way what you need to do is install vuze toolbar http://www.vuze.com/gettoolbar/ Then it will install the folder toolbars in applications. Well go into the then click on vuze and in there theres this icon that says uninstall, double click and problem solved. I hope this helps man !
Yes! macwheadon has the answer. I tried forever, hours, of scrounging around deleting files and un-installing and re-installing safari and FF.
Was loathe to download anything vuze related again but that worked! Just remember to delete everything after and find that 'conduit' file in users-library- applications support. Job done!=)
