Here is a list of routine maintenance you should be performing on your computer each and every month. If you use your computer on a daily basis or surf the net everyday, you should perform this maintenance weekly. There are other things that many people do on a monthly basis, but here is what EVERYONE needs to do, at least monthly and how to do it:
Clean out all temporary files -- you don’t need any of them and they just take up valuable hard drive space.
Clean out your "cookies"(电脑中的一些数据)—the things that lead internet trackers back to you. Remember that if you clean out all your cookies, you will have to log back into any sites you set up to log you on automatically—such as this site.

Run a Virus Scan.

[单项选择]For more than four centuries, to be Swedish was to be Lutheran (路德教派的). Every newborn there was automatically registered as a member of the Church of Sweden, the official Lutheran denomination. The marriage between church and state was so strong that it took an act of Parliament to change the prayer book, and bishops were chosen by members of the Cabinet.
But Sweden, like the rest of Western Europe, has been transformed by a wave of immigration. The Stockholm phone book is still full of Larsons and Ericssons, but there are also listings now for folks named al-Ghusan, Ng, and Singh. Many of these newcomers have brought along their own religion. To the Swedes, with their unbending commitment to egalitarianism, it no longer seemed fair to give official favour to one faith over the others.
