Solutions to slow network speeds caused by network viruses

1. Poisoning 2. Too much software.

3. Software Conflicts.

Fourth, the system has not been installed for a long time.

Fifth, the hard disk has been working for a long time, and there are problems such as speed at high temperature.

6. Bandwidth (fast speed without Internet access).

7. Memory aging.

8. Sorting out the internal garbage of the computer.

There are a number of other reasons.

Reason 1: The fault of local viruses and Trojans.

This is the answer that many netizens think of for the first time. Yes, infection with certain viruses and Trojans can indeed cause slow internet speeds. However, how many netizens will verify it?

Verification Step 1: Use anti-virus software to check for viruses thoroughly. This is the easiest way to do this, but it doesn't always work out.

Verification Step 2: Observe the CPU operation and network conditions. If the CPU is running non-stop for no reason, and the network connection is constant, it is possible that a virus Trojan is the cause.

Verify Step 3: Dos commands. Ping under DOS to see how responsive the network is.

Cause 2: Server issues.

Surfing the Internet has to go through many servers to reach your destination. Therefore, the server directly affects the user's network speed. Network congestion can also slow down internet speeds.

Cause 3: Network viruses targeting the server.

Network viruses that target servers tend to slow down or bring down networks. However, it is not the user's business to solve this problem.

Cause 4: Local system issues.

The system takes a long time and often fails. If the internet speed slows down suddenly long after the device is turned on, you may want to restart it to see if it solves the problem. Sometimes, it is even necessary to reinstall the system to solve the problem.

Reason 5: The CPU is busy working.

The CPU is busy working and will directly affect the network and computer speed. So it's necessary to check how your CPU is working when the internet is slow.

Is there a fixed IP? If so, it is likely that the resource has been stolen. Do you have a firewall? What is the setting level?

Usually, fixed IPs are easy to be implanted with Trojans and are treated as "broilers". Even if the system is reinstalled, it will be re-implanted in the Trojan soon (because the IP has not changed). Or maybe it's because the individual software you're using now is bundled with a Trojan horse, and every time you reinstall the system, you reinstall that software, and you also install the Trojan.

Solution: Reinstall the system in a clean state (no other software is installed, except for the driver), install the firewall and Trojan scanning software. Note: Do not surf the Internet without firewalls and Trojan scanning software.

Your problem is very wide, you can't judge correctly, it is recommended to upgrade your antivirus software to safe mode to disinfect first, be sure to go to safe mode, in normal mode the virus will be cross-infected, and then you can use it"Super Bunny Magic Setting"or"Yahoo Assistant"and other optimization tools to optimize and repair your system and IE! In addition, you can use batch processors to make a system junk cleaner and give your system one"Slim"The figure, if needed, can be sent to you!

The easiest and most effective way to do this is to install a genuine antivirus and update to the latest version.

Recommended Jinshan Poison Tyrant and Ruixing, the market price of Ruixing is about 100.

Antivirus, use Ice Blade software to view the process, close the illegal process.

Antivirus. Break the network cable first, and kill them one by one.

The flooding of ARP is a result of very slow and even paralyzing the Internet.

Is there such a poison? My computer has been slowing down a lot these days, I don't know what's going on, but it's not slow down at night.

There are too many factors to consider when checking for slow network speed, so let's talk about what comes to mind first.

Troubleshoot software issues first.

Thinking about physics.

Software problems include: network optimization, antivirus, program traffic monitoring, and physical problems include: network ports, network cards, access devices (modems, switches, routes), access rates, and access cables

Clean up the computer, most of the slow network speed is the operator's problem, you have to go to him.

Spend money to upgrade your internet speed.

There's really no way around the rest.

There are many possibilities, and the space is full and will be affected.

The first is to find a telecom upgrade. Second, optimize with the numerous network optimizations that come with 360. The configuration of the host is also important.

Replace the network or find a network engineer for repair.

Increase broadband speeds.

The Pro version of WindowsXP retains 20% of the bandwidth by default, which is actually useless for us individual users. In particular, it is better to make the most of it if it is idle.

Enter in Start Run to open Group Policyr. Find Computer Configuration Management Template Network QoS Packet Scheduler, select Limit Retained Bandwidth on the right, select Properties to open the Limit Retained Bandwidth Properties dialog box, and select Disable. This frees up the reserved bandwidth, which is very useful for friends who surf the Internet.

Internet speed generally refers to the length of time it takes to request and return data when the computer or hand reed hall machine is on the Internet, when uploading and returning data. To improve the network speed, it depends on the access network of the network service provider.

How to solve the problem of slow network speed and sluggishness of the electric hood.

There are several reasons for this:

According to what you said, it is likely to be poisoned, kill and kill the virus. It can be solved! Browser viruses are included.

If you don't have poison, use 360 or Super Bunny to fix the IE.

Then you can use Optimizer to optimize and clean up your computer, and you can react quickly.

Right-click on "My Computer", "Properties", "Advanced", "Performance Settings" selection"Optimal performance","OK". The computer will also respond much faster. Neither here nor the multi-visual setup is useful. Can be customized.

There are actually two types of slow internet speeds. One is that the network speed is really slow, and the reasons will not be repeated. The second is that the web page opens slowly (the network speed is normal) is not a slow network speed, it may be caused by a medium virus, or the computer is running slowly, or there is a problem with the Internet Explorer, or the system is too much junk and so on.

So treat them differently. The best way to solve the problem can only be solved by prescribing the right medicine, and it cannot be blindly said that it is a problem of network speed.

The first thing is to check the network ant problem, and if you want to do it, it's the machine.

It may be that you have too much junk on your computer.

Can be cleaned with Optimizer.

2. Your disk is too fragmented, so you have to defragment it instead.

3. You have too many boot items.

4. Your machine is old.
