1, pay attention to the installation of the application software
Many “free” tools with spyware are hard to kill. Use the software name you want to install and “spyware” as a keyword, search on the Internet, if you find any spyware report, do not install.
2, to keep anti-virus and anti-spyware updates
Malicious software often makes garbage in the registry, but also starts unnecessary Windows services, doing a lot of things to reduce system performance, and even lead to the system simply can not work.
3, as far as possible without “administrator” account login
Do not always log in with the “administrator” account, especially when copying files from outside to your PC. If you just log in with normal access to the user, most malware can not succeed, in the control panel “user account” can be created.
4, regular finishing hard drive
Serious hard disk debris will significantly reduce the speed of your computer response. So you need to clean up the disk on a regular basis, disk cleanup is very simple, first click “Start”, then point to “All Programs”, “Accessories”, “System Tools”, and then click “Disk Cleanup”. If you have more than one drive, you are prompted to specify the drive to clean up.
5, regularly clean up the Windows registry
Prevent Registry Spam from using tools such as Registry First Aid. Do not use Outlook Express, which stores the spam filter in the registry. But there is one thing, before the clean-up must first back up the registry.
