you have a security problem antivirus 2009

老是跳出you have a security problem，点开来是一个网页让我安装antivirus 2009，进程里比以前多出了ert515241.exe这个进程，还有个~tmpe，结束了~tmpe，就不跳出了。请高手给出办法详解，谢谢~！

have you a book? you are have a haircut 还是you have a haircut ？ you have a nice figure have you got a computer？？ Do you have a cold ? DO you have a cold have you a friend?是什么意思？ Have you got a pen? You have a point there, Can I have a word with you?
