Malware from KittyCatS Website?

[Oselkhandro Resident]

This is all very interesting information. I do not access any file or video sharing sites, so I did not get the infections from that. I did, however, access the web browser from inside SL on Firestorm. Usually, I access this from the Cattery portal that I keep rezzed in my livingroom. Does this mean that accessing the Cattery from the in-world option ("visit Cattery") is dangerous because it opens an SL internet browser? Is it only safe to enter the Cattery from one's own non-SL connection (Internet Explorer, Firefox, etc)?

I am a heavy user of SL and on that site a lot (I am retired, so lots of time). I also use the Cattery site heavily, but I do not use the HUD. I did recently try to access a video feed on SL to view the Kentucky Derby (unsuccessfully). Did trying to access a video on SL cause my infections?
