Nowadays, there are many attachments containing virus and other softwares able to hack into our computer. Firstly, if there was really a h1n1 prevention medicine, won't everybody be rushing out to buy it? Also, if it was really that effective, they won't be doing advertisements via email, but encourage people who tested and prove it to inform their friends and family? This is not only much more effecient, but also safer. Thirdly, the virus is rather under control in Singapore. Although people died, the schools are not closed down, which means that there is no reason to be alarmed, as the situation is in control. Instead of speculating, people who forward this messages, people should think about what they can do to prevent themselves from getting infected. Furthermore, if such a prevention has been invented, it should be all over the news, which is not. There are many forms of computer virus. Some slowen the computer, some erase all the files and saved documents, some simply hang the whole computer. The different kind of virus have one thing in common- they both damage the computer. Therefore we should not randomly open files. :)
