connected to the Internet or by receiving an email from some cyber-creep.

The Mac has always been vulnerable to phishing schemes and to what are called Trojan horses.


A phishing scheme is when you get an email or an Internet window opens up saying that such and such bank or credit card company wants you to log on and give one of your passwords. Banks never do that. Another scheme that has afflicted Windows users is a browser page that pops up saying it has scanned your disk and has found viruses; you are then encouraged to send money for them to clean up your computer.


Even though this scam had all the design elements of Windows OS, some Mac users someone got roped in.


Trojans are another problem entirely. These are full blown programs that purport to be one think, but, in truth, they are something quite else. Since these are full blown programs, your computer will prompt you for an administrator user name (most Macs run as Administrator Accounts meaning that YOUR id is the Administrator ID).


Once installed they can do anything a Windows virus can do EXCEPT TO SPREAD TO OTHER MACS. Meanwhile they can be recording keystrokes and stealing all sorts of data.


Some of these Trojan horses are distributed with pirated software and others now come with offers of free programs.
The example quoted later is of a really cool FREE screen saver.


I have warned friends and colleagues for years never to send me FREE greeting cards that take me to some animated web-site; ditto for those pesky party invite sites that keep a list of all guests. These sites may not be setting you up for Trojan horse, but they are mining a list of active e-mail addresses that they can sell to the folk who to hawk shady pharmaceuticals, stock market scams and the like.


Always keep this in mind: If the service is Free, it is not likely a charity: they will have a business plan to make money.


Now please have a look at the links below. These are not intended to put you into a panic. Just to educate you on proper Internet Hygiene.


Many of these reports come from people who sell Mac Anti-Virus programs, so there will be a natural bias.


As for anti-virus programs, many are more trouble than they are worth, but if you do experiment with software or do a lot of downloading of music, TV shows, and Movies, there are programs that can just monitor your “Downloads” folder without putting a lot of strain on your computer.

iPhoto 11 Upgrade, but take precautions


The last time I sent out this mini newsletter I had cautioned against upgrading iPhoto to iPhoto 11. I was remiss in not following up that Apple had repaired the program with the repair provided through
“software update.”


One never knows for sure with an iLife Install Disk if the program needs to be updated or not, so it’s a good idea to install the software and then run software update before you let the program update your iPhoto LIbrary. Also good computer hygiene is that you always have an update backup especially of irreplaceable data, typical of most photo libraries.

 

Next OSX Lion 10.7


I have some new concerns coming up. It
is still early to know for certain, but some testers of the beta versions of the next Operating System, Lion (10.7) have remarked that the OS no longer supports “Rosetta.”  Rosetta is the brilliant software that was able to convert the old Power-PC programs on the fly to function on the Intel platform.


Before you update to Lion when is becomes available, please give me a call or read various Mac news sources to see what the compatibility situation will be.


You may think that you are “scott-free” if you have never owned a Power PC (G4 G5 etc.) Mac. In fact you may still have programs that require Rosetta on your hard drive. Small software companies (like the Canadian Tax Preparation TaxTron, use the compatible style of software because their market is not very large and they need to include Power PC users as well as Intel users to make creation of their excellent economical software available to the widest audience.

 
Mac Malware


First let me assert that there is not a known OSX virus in the wild that can infect a properly updated Mac.


What I mean by a virus is some bit of malware that you can get just by having your computer connected
