Antivirus slowing down computer causes
Antivirus software needs to be in memory or look for virus signature file. This is a huge amount of computation, low profile machine speed impact is obvious.
In addition to CPU resources, the anti-virus software will need to run the program, the file open/save time for additional disk read operation. Frequent hard disk read blocking other processes and virtual memory of your hard disk read and write operations, making the CPU and the machine must be waiting, thereby holding back for a machine.
(In process management overhead? please know friends added)
Optimal use of anti-virus software
Eliminate unnecessary scan operation
There will be no threat of files to exclude from the scope of the scan checks, will greatly reduce the antivirus software on the system pressure and delay, and improve overall operating efficiency.

Because not all files can cause the spread of viruses; at the same time, even if the computer has a virus of the original data, it also needs to be running the opportunity may be activated. Thus, under normal conditions, the following should be excluded from the scope of killing the antivirus software:

Compress documents: * .zip .rar/*/*/* .cab .gz
Note: If the compression package really viruses, they are only in the extracted may be running. In the extract, realtime protection antivirus software has to be clean, compact package with a virus and will not cause harm.
Because of the extract is high intensity calculation process, therefore cancel the scan compressed files will effectively reduce the CPU usage of antivirus software.
QQ chat: * .db
QQ chat, this data file is repeatedly modified, thus also be anti-virus scanning repeatedly, seriously affecting the hard drive performance. This type of file is not a virus, don't cancel the scan when more pending! (* .db is also possible that other software's database files)
Large media files: * .wav .mp3/*/*/* .bmp .tif
These huge media file is not a virus. Cancel their scanning can accelerate the speed of the open folder.
*.ttc/*.ttf/*.txt
These files can be excluded from the scan, but is not a major problem. More work needs to be excluded data can search your hard disk > 2 MB file, depending on the circumstances excluded (for example you are the artists, you might also need to be * .psd excluded).

Reduce manual scans
All scan all disks will spend a lot of time, usually no need to do so.

In General, scan the system disk, other spare ProgramFiles directory, download software, storing them in the directory. Typically, if a virus, in most cases, one or two minutes you will have to reflect the (usually scan the windows directory on alarm).

If you feel there is an exception, then the machine and a full scan.

Security expert usage
That is, use the previous method, the anti-virus software will still cause the system speed. Antivirus capability higher users tend to have their unique usage.

Intermittent virus checking
Many experts usually does not turn on antivirus software, are only used when exceptions to check them.

Ordinary users can learn the practice, generally without anti-virus software, every couple of weeks set out idle time scan. In this way, the usual computer speed is guaranteed.

The truth is: episode too soon or ** large vicious viruses can cause particular concern, thus affecting dissemination; but mild virus, spread the opportunities even greater. As a rule of thumb, computer data in one or two weeks by virus seriously ** is unlikely, therefore, that the above-mentioned intermittent antivirus method.

Need a reminder about are:

Even if you turn on the best protection measures, important data backup is necessary!
And antivirus software, firewall best always.

With system monitoring tools replace the virus checking
If you are on your own computer is very confident that may wish to turn off antivirus software. Usually only often enable Task Manager, System Monitor taskinfo software view health, is an exception and then start the antivirus software to check. This approach eliminates the huge overhead. anti-virus software

Avoid using multiple antivirus software
Multiple anti-virus software at work, not only slow, system also may deadlock, crashes, and between competing for the system of control over the antivirus software.

If you want to use multiple anti-virus tools to guarantee system security, please note that while only one in the work.

In addition, the data show a lot of antivirus software is installed at the same time (not run) has already begun "many elephants are charging", such as "destroyer" discovery system equipped with Kaspersky Anti-virus will refuse to install, uninstall some antivirus software may cause other anti-virus software stop working or an exception occurs.
