The machine is relatively broken, and it runs very slowly after installing antivirus and firewall, c

Since your machine is relatively broken, then I will provide you with a better solution.

First of all, all antivirus software is slowing down, and it's seriously slowing down, so the best thing to do is not to install antivirus software, don't rush, what's the problem, keep reading to find out.

Secondly, if you don't have antivirus software installed, what if there is a virus, so you have to do it here.

1. After installing the system and the necessary application software, install the anti-virus software and carry out a comprehensive anti-virus on the machine2, and uninstall the anti-virus software on the premise of ensuring 100% virus-free, that is, delete the anti-virus software and install the "Restore Wizard".

3, and then you can rest assured that you can use the computer boldly If the machine is unfortunately infected with a virus, you only need to restore it with one click and return you to a pure XP system within 5 seconds.

Finally, good luck

Since it is a broken machine, then do not install antivirus software, installing antivirus software will be slower than a cow, it is recommended that you install a freezing point or shadow system on this machine so that you will not suffer from virus invasion Moreover, the speed of the machine will be several times faster than before

If you feel that there is a virus in the machine, restart it and the virus will be gone

No, some poisons can't be killed, you just go and buy a memory module, which can improve the running speed of the machine.

Seriously, if your machine is really not good, you can not install antivirus software, but for safe use, it is recommended that you install a 360.

If you have access to the Internet, it's best to turn it on, and if you're just playing with a single machine, do a homework or something, turn it off.

Regular anti-virus, that's it.

No problem, Security Guard 360 is better, I recommend you try it.

What can be turned off is that the safety factor of the computer will be reduced.

Antivirus software doesn't take up much memory. It's okay if it's not closed. I do this every day. But I don't get into some boring **.

It is indeed a resource that is taken up and monitored at all times. I believe that the landlord's computer configuration is lower.

Do you want to be fast? Occupy the resources must be slow to sprinkle.

If there is more software, will it become faster if it is not slow?

There are a lot of people, and your house still occupies space, not to mention the computer?

This is common sense, and of course many people have encountered it. As long as it's not a classic machine, it's generally not too much of a problem.

This is a normal phenomenon, but you can compare and choose a soft kill that occupies less system resources. On the other hand, it is recommended to turn off the computer's own firewall after installing the killing software, which is useless and troublesome.

Both antivirus software and firewalls will take up system resources, and the impact will be more obvious on old computers with low configurations. It is recommended that you install Kingsoft Poison and Kingsoft Net Shield, which do not occupy a lot of resources.

1.Too many cached files on a long-term web page will significantly affect the speed of the Internet, so if you want to improve the speed of surfing the Internet, you must regularly delete the temporary files in the cache.

The specific operation steps are: open the Internet Explorer tool Internet Options to delete all Internet browsing records and junk.

2.Malware can severely slow down the internet, scan for "malware" and empty all the malware that comes out.

3.Your computer has been infected with certain viruses and Trojans, which can cause your internet connection to be slow.

First, use anti-virus software such as Kingsoft Anti-Virus to comprehensively check the poison and anti-virus. The anti-virus software should be upgraded every day, and the virus should be checked once a week, so don't be afraid of trouble.

Rising is garbage, it is recommended that you use 360 + small A

The main reason is that our memory is large, and it is not possible to install anti-virus software, which is easy to be poisoned.

It's a bit of an impact, but the impact shouldn't be too big, there are too many browser plugins? The toolbar, or the browser itself, is recommended to start with this.

Don't do that, landlord! It's too dangerous not to install antivirus and firewalls.

In addition to its own butler cloud anti-virus engine, Eagle Eye's second-generation anti-virus engine and system repair engine, Xun Computer Manager also integrates the Kingsoft anti-virus engine and the anti-virus engine of the world-renowned anti-virus software Xiaohongumbrella, which has strong anti-virus capabilities.

In addition, it occupies less system resources and occupies less memory and CPU, as shown in the figure below.

Hope it helps.

What anti-virus, what fire prevention is better than your own prevention. We should pay attention to the following points in the process of daily use: (1) Try not to use pirated or unknown software.

2) Back up the hard disk pilot and master boot sector data, and back up important data frequently. (3) Develop a good habit of frequently checking the hard disk and each foreign disk with antivirus software. (4) Antivirus software should be upgraded regularly, and the general interval should not exceed one month.

5) Install a real-time monitoring antivirus, which is not a one-and-done solution, antivirus software may not be effective against all viruses, and viruses update quickly. (6) Pay attention to all kinds of abnormal phenomena of the computer at any time, and once found, you should immediately check it carefully with anti-virus software. Antivirus software is an effective tool to prevent virus infection, and you should try to have as many sets of antivirus software as possible, because each antivirus software has its own characteristics.

7) Some viruses are mainly transmitted through e-mail, which is called "mail virus". They are usually spread through the entrainment of an "attachment" in an email, and if you run a virus program in that attachment, you can poison your computer. So, don't easily open the attached file in a letter from a stranger.

It is necessary to install,Three software to protect the computer system from external viruses,It will occupy a part of the computer's memory,But it will not affect the running speed of the computer,You can not install it on the C drive,Hehe。

Well, every time the computer starts but it runs automatically, then it takes time to start Rising, and it is not the main reason whether it occupies memory or not,

No, but the computer will be slower when running Rising and the upgraded version! Be sure to put it on, Rising is very easy to use. If there is a virus in the computer, the system will run slowly or the system will be paralyzed!!

No, after the installation of Rising antivirus software and firewall, it was just going to be upgraded, so it felt a little slow, but it won't be after entering the normal track, and the reason for the slowness may be because there are too many things on the desktop, so it affects the boot speed.

The installation of any software will affect the speed of your computer.

If you know more about computers, you can use 360 security guard, little red umbrella, plus comodo firewall, this is a very good combination, if you are still a computer novice, you can use 360 security guard, plus 360 antivirus software, you can meet the needs of protecting computer security! Of course, no matter what system security software you use, the most important thing is to have a good online habit.

I have been using Kaspersky and 360 Security Guard combined, this combination has been used for at least five years, the effect is good, believe me, free 360 antivirus has never been able to catch up with world-class antivirus software, otherwise what do people charge, of course, whether you want to buy or not to buy it depends on yourself.

360The protection software occupies a relatively small amount of memory, and it has always been used in this combination, and indeed the recognition of this combination is very high, and the surrounding computers are installed like this, and the memory occupied by the computer is not very large when the three protection software are opened.

I think 360 is too troublesome, Kaspersky costs money but the effect is very good, you can also use Rising + 360 Security Guard, it is better not to use 360 Antivirus.

Comodo firewall and ESET NOD32 work best.

360 antivirus is not very memory-intensive, the computer configuration is low, change the computer.

Kaba super occupies memory,And open**,Kaba will first scan that**for viruses,Open,You go to the next NOD32 bar,More than Kaba input。

That's right, if you install antivirus software, it takes up a lot of memory, and the computer is very slow.

You load 3 programs at once,512M memory can't bear it,It is recommended that you either reduce the process,Or increase the memory,1G DDR667 should be fine!
