A plugin is a program written through a specific standard application program interface, which can only be run under the program’s specific system platform and cannot be run separately from the specific platform.
For example, in IE, after installing the relevant plugin, the web browser can directly call the plugin program to process certain types of files. Plugin’s positioning is to develop programs that realize functions that the original system and application software platform do not have.
Characteristics of malicious plug-ins
Some plug-in programs can help users browse the Internet more easily or call online auxiliary functions, and some programs are called adware or spyware. Such malicious plug-in programs monitor users’ online behavior and report the recorded data to the creator of the plug-in program to achieve illegal purposes such as advertising, stealing games, or bank account passwords.
Because plug-in programs are issue by different publishers and their technical level is also uneven, the plug-in program is likely to conflict with other running programs, resulting in various page errors, runtime errors, etc., which block normal browsing.
The disadvantages of Plugin are mainly reflecting in three aspects:
- Very dependent on plugin developers to provide updates. When we install a plug-in, it is equivalent to handing over part of our website control to others. If you use a free plug-in, this may be particularly troublesome, because the developer does not owe you anything, and he does not need to update it.
- If some plug-in code is not perfect enough, if the optimization is not good enough, it will greatly reduce the speed of your website! Anyway, yes, my website is really slow… If you install a free plug-in, it is best to make sure that it is a plug-in with a lot of users and praise, look at the plug-in experience. The more general users there are, the greater the opportunity for developers to provide updates. After all, other people’s development is not free, they have to make money.
- Be careful with plug-ins of page generation type. Although these plug-ins can do some amazingly efficient things, most of them are resource-consuming and occupy a lot of CPU, and they will even slow down your website. In addition, if the developer no longer provides support, your website may leave many problems, and many pages cannot be open! It is advice that when continuing to use program plug-ins such as page builders, carefully consider whether all options are safe!
