...SOLVE/REMOVE THEM? My colleague sent me a PC prank, which I thought of course was a clean link. Now I can't save any file because my laptop is using this temporary setting anything I save will be lost once I go back to the normal setting. The problem is he also doesn't know how to undo what he sent me.

The desktop shows: "WARNING! Spyware detected on your computer! Install an anti-virus or spy-remover to clean your computer!"

Then I suddenly have this Anti-virus XP 2008 magically installed on my desktop... Please, please help! I have a deadline today and I can't work properly...
And by the way this thing seems to block my access to pages if a page is idle or I click on the Browser for the first time it shows a white page that says: Insecure Internet activity. Threat of virus attack
-----------------------------------------------------
Due to insecure Internet browsing your PC can easily get infected with viruses, worms and trojans without your knowledge, and that can lead to system slowdown, freezes and crashes.
Also insecure Internet activity can result in revealing your personal information.
To get full advanced real-time protection for PC and Internet activity, register Antivirus XP 2008.

something like that.... 10 points for the pereson who can help me... PLEASE!!!!
