apple did it for me

 

It was a year old article that was pulled when it was discovered. Just because protection is recommended does not mean there is an actual virus.

 

ok heres a newer one

Its not a virus, its a trojan. There is a big difference.

Did you even read the article?

 

That's not a virus; it is a trojan that is included in pirated copies of iWork 09 that people download from torrents. A trojan is not a virus.

 

thank you very much

 

trojan/virus...whatever

both things a good virus scanner would hopefully find

 

What about helping the OP instead of fighting about the existence of viruses on macs?

 

Do you remember if the problem occurred after a software installation?

 

Corrupt font maybe?

You said it showed a strange "B".
Corrupt files can sometimes mess up a whole bunch of things.

 

Try changing the font to something else and see if it makes a difference.

 

Although there are virus for Mac, Apple has long issued the respective security updates and pushed them to a point in which a Mac today would be immune.

There were virus for Mac, just none right now and that doesn't necessarily mean there won't be. The trojan going around in iWork is not a virus. Virus by nature are destructive and do damage without a user's permission. Anything that requires user authorization to be installed is an app/daemon or simply a program. This program has capabilities that allow it to run the machine even though its not supposed to. Thus, it leave the realm of application and becomes a malware and is now known as trojan. Since it came an innocent app and turned to be evil. (to say something)

Anyways, back on topic more likely, its a glitch in your drivers. Also, maybe a problem with your screen. Try calling Apple Care or taking it to an Apple Store.

 

whats the difference between being able to capture the glitch with a screen capture or not?

 

Have you tried a PRAM reset. Might also want to run an AHT

Also check you don't have duplicate fonts running

 

no duplicate fonts, zapped the ram, but what is the other thing?
