received a forward – via ppt. – on old mac w/ no anti-virus, and now i have email virus. any hope 4 me? the forward had some great pix of a new hotel in singapore, but now i have all these squiggly thingz which, once hit on, erase what you’ve written. they show up on any new emails i try to write as well. also, am concerned about all my friends i forwarded that stupid hotel to.
