Recently on ICQ I have received several different attempts at authorisation from somebody with a webpage that tries to install something on my PC. What happens is: I get a request to authorize this anonymous person. There is no information on the person following the request, but there is a second message. This message contains an URL. It's when you click the URL it happens. I do not know what "it" really is, as the virus software on my machine was going crazy, the Volda College network version of dropping steel doors to contain the damage.
So: for ICQ users out there: Don't click the URL if one part of the adress is "lonar". (As in the crater. Perhaps a meteorite carried the computer virus here?)
