I'm using an older version of AIM for chat since I'm not impressed with the current version, and got an e-mail today, supposedly from AIM, saying my account would be deleted if I didn't update.

I noted the address (do NOT go there!):

update.aol.com.pikoe.com.pl/products/aimController.php?code=6443563173248524832643549443869

The strange stuff at the end is a classic warning sign. ".pl" may indicate a Poland site. AOL is not based in Poland.

This is the actual AOL download site:

products.aim.com

That's it. Very simple and straightforward.

I checked my shields, then clicked the link. The defenses blocked two viruses trying to get in, even before I clicked the "update now" button (which I didn't). The website looked quite authentic.

Be careful out there.
