Why is my computer slow after installing antivirus software, but fast if I don t install it?

Because a good antivirus is very memory-intensive, because of your daily operations, he has to monitor you, including when you open documents (word, excel, etc.), open web pages, open programs, it has to access and scan it, so as to achieve the purpose of monitoring viruses at any time, since it resides in memory, that is to say, it consumes system resources, such as memory capacity, Processor time, etc., will inevitably have an impact on the speed of the computer, so it is normal for the boot speed to feel slow, and for some computers with poor configurations, it will even affect the speed of opening applications, so it is normal to be slow.

Because a good antivirus software manages a lot of things, including your chat tool, online banking, ** account or something, so there is a contradiction, a little slow, but I think it is much better to be slower than to deal with it after being poisoned.

There is no complete solution, but there are some suggestions that can greatly mitigate the effects of system inefficiencies or even make them feel at all if they are properly disposed of. The first suggestion is to increase the memory of the system, when the system memory is more than 512MB, the memory occupied by the antivirus software is insignificant;The second suggestion is to upgrade to a faster processor, only on computers above P42G, the CPU resources used by the antivirus will not be felt;The third suggestion is to turn off unnecessary services. After the computer boots up, the default system services and anti-virus software services may not all work for you, so turning off all the services you don't use is a good way to speed things up.

Just turn off the firewall while you're playing online games, but don't turn it off until you're playing!!!After entering, switch out and close it, close the method: start the column in the lower right corner, find the firewall icon, and then right-click and select "Exit".

It's normal to be slower, sacrificing speed, but keeping your computer safe, so it's worth it!!!

Maybe your computer configuration is not very high, antivirus software takes up resources, and some of them take up a lot of resources.

It's like a person, if you work too much, you will definitely do it slowly.

Because the antivirus software runs in the background, when it runs, you don't see it with your own eyes, so you get the feeling that the antivirus software only works when the antivirus is done, in fact, it runs automatically as soon as the computer is turned on, and as the gentleman above said, it is also quite resource-intensive.

Upstairs is so detailed, but not to the point, because the antivirus software has a "monitoring center", this thing takes up a lot of memory, but the station CPU is relatively small, it is recommended to use Jiangmin antivirus software, save resources, Kaba is also good.
