I've reported this case to the ISP and waiting for their reply.
Furthermore, system technician is now working on it. The reason why the icon didn't show up this morning becoz' system technician has removed the icon. However, it shows up again after 5 pm and I still don't know what happened of our server, it still needs time to investigate and fix it. From what I know, if you didn't click that icon, there would be no problem. However, if you have already clicked it, I suggest that you should run any anti-virus software and also any anti-spy ware as well as ad-ware in your computer in order to prevent infection.
The following link is the free anti-virus / Anti-spyware website:
