1. Organize the hard drive regularly
Serious hard disk fragmentation can drastically reduce your computer's response speed. So you need regular disk cleanup, Disk Cleanup is very simple, first click Start, 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 you want to clean.
2. Regularly clean up Windows registry
Prevent registry garbage from using tools such as registry cleaner. Do not use outlookexpress, which stores the spam filter in the registry. Registry cleaning Tools There are many online, I recommend two models of vacuum cleaners and regclear. However, there is a point where you must back up the registry before you can clean it.
3, as far as possible without the "administrator" account login
Do not always log in to the admin account, especially when copying files from the outside to your PC. Most malware will not succeed if you only log on with a user with normal privileges. Creating a limited account is simple, you don't need to introduce it, you can create it under User accounts in Control Panel.
4. Be careful what you install
Many "free" tools with spyware are hard to kill. Use the name of the software you want to install and "spyware" as the keyword, search the internet, if you find any spyware reports, do not install.
5, keep antivirus and antispyware software update
Malware often makes garbage in the registry, it also starts unnecessary Windows services, does many things that degrade system performance, and even causes the system to not work at all.
