hey,i dunno if tis is my prob..when i was chatting earlier, suddenly i receive a weblink message from my friend who is offline...then a minute later another same weblink message from another friend who is also offline...

is it my pc infected by virus or my friends'?

The following is a breakdown of what usually happens: first you will receive a message containing a web link and a text that tries to convince you to click on the previously mentioned link. If you do, you will be directed to a certain web page where you will be asked to provide some private info. Keep in mind that all the pictures on the site are linked to search queries and all the data that you provide will be automatically verified.

How is your data verified? By simply using it to log into your own account. Once in, all the people in your list of friends will receive the same spam message that you did (the one inviting you to click on the link). They will most likely think the message comes from you, but in fact you had little to do with it.

but the thing is,they r offline.if offline how to send the weblink to me?and besides the weblink message dint appear right after i signed in but rather after a few hours of chatting
