On demo @ virushuo (http://www.donews.net/virushuo/), you can see against avast! Introduction, installed a try, as it is true: free, powerful, small resource occupation, many types of virus detection and removal. It is really worth recommending.
For individual users, avast! The only requirement is that if you want to get a free upgrade, you can perform a free upgrade for 14 months after registration. If you do not buy an upgrade after expiration, you can register it again. That is to say, you can always get updates for free, including software updates and the latest virus database.

There can be one more pirated software on the computer. We look forward to oo2.0 (OpenOffice 2.0 ).
PS: Recently, the computer ie opened the page. If the selected content often pauses, I wonder if Google Toolbar 3 is a problem. It seems that this problem has not existed before.
