Internet blocked by virus, how to fix

Why is my internet connection so slow?

No matter how fast your internet connection is, there are times when things slow down to a crawl. This article describes what problems can occur, how to fix them, and how to optimize your Internet connection.

Windows has a built-in troubleshooter that can automatically find and fix some common connection problems.

Open the Internet Connections troubleshooter by clicking the Start buttonand then on Click Control Panel. Enter the text in the search boxTroubleshooting and then click Troubleshooting. Click belowNetwork and internet onConnect to the internet.

The connection type plays a role

The type of internet connection you are using is the most important factor in your connection speed. The three most common types of home Internet connections are dial-up, DSL, and cable. If your choice is yours, cable is the fastest, but both DSL and cable are faster than dial-up connections.

Many Internet providers also offer the Fiber Optical Service (FiOS), which connects to the Internet using light over an optical network. In your home, the computer is still connected by copper wires. The advantage of FiOS is that higher speeds than traditional copper wire connections such as B. DSL or cable are possible. Some internet service providers offer several options depending on the region. FiOS is more likely to be available in most populous regions. Contact your telephone company or Internet service provider for more information.

If you are using a dial-up connection, there are a number of good ways you can optimize your Internet speed. First, use the fastest modem possible. The fastest possible modem sends and receives data at 56 kilobits per second (Kbit / s). Most of the time, the full speed of 56 Kbit / s is not achieved, but with a good telephone connection at least 45-50 Kbit / s should be achieved.

Second, make sure your phone line is in good working order. If the phone wiring in your home or office is old or damaged, it can pick up stray signals or crosstalk from other phone lines. These problems slow down your Internet connection because the modem has to send data repeatedly until it can be transmitted without interruption. Check your phone cords to make sure they are not damaged, worn, or tangled with other power or telephone cords. If you notice crackling on the phone, contact your telephone company to check that the lines inside and outside the home are in good condition.

Tips for wireless network users

When you connect to a wireless network (WI-Fi), Internet connection speed can affect both your computer's location and other wireless devices in the same area. Wireless networks use frequencies that are different from those of other devices such as B. Microwaves or cordless phones. A cordless phone with 2.4 gigahertz (GHz) next to your WLAN-enabled 2.4 GHz laptop can cause interference or completely block the wireless connection. If you want to make calls while browsing the Internet, use either a wired phone or a cordless phone that uses a frequency other than the wireless network.

Proximity to the wireless access point or router, as well as physical obstructions, can affect the quality of your Internet connection. To improve the connection speed, move closer to the access point and make sure that there are no physical obstructions between the access point and your computer.

Computer ailments: spyware, viruses and other programs

The health of your computer can affect your Internet connection. Spyware and viruses can undoubtedly cause problems, but the speed of your Internet connection can also be affected by add-on programs, the amount of RAM on your computer, the amount of free space and condition of the hard drive, and the programs that are running.

Two of the most common causes of poor Internet performance are spyware and viruses. Spyware can slow down the system by affecting your browser and consuming the internet connection on its own. Spyware monitors your internet usage and keystrokes, causing delays. The problem is exacerbated when multiple spyware programs are running at the same time. If the problem is extremely serious, you can lose your connection entirely. To get Internet performance back, you should regularly run antispyware to get rid of all spyware infections.

Computer viruses can also cause poor internet performance. When a virus hits a computer, it installs computer code to spread itself. Usually they send out copies of themselves via email. Some viruses can multiply with hundreds of e-mails per minute, leaving little processing power and Internet connection bandwidth for other purposes. Often times there is no obvious sign that a virus is running. Therefore, the anti-virus software should be kept running.

Browser add-ons also cause performance issues. Browser add-ons are programs such as B. Multimedia add-ons, search bars or other programs that are usually displayed on the browser toolbar. Many browser add-ons can contribute to optimal browsing by adding multimedia or special document views. However, some add-ons can slow down your internet connection. If you suspect that add-ons are causing the slow performance, try starting Internet Explorer in a mode with the add-ons disabled. The add-ons are only deactivated for the current session. However, if you find that the performance improves, you can turn it off permanently through the add-on management. To access Internet Explorer Add-On Management, click the button Extras and then on Manage add-ons.

Like all computer programs, Internet Explorer requires a certain amount of processing power, memory, and storage space to run efficiently. Each web page displayed is first downloaded to the main memory and then saved in temporary files. Other high-performance and memory-intensive programs can compete with Internet Explorer and cause delays. If you think your Internet connection is slow and other programs are running, close those programs. If you have multiple programs to run, consider adding more memory. Low disk space can also lead to performance problems. You can increase disk space by deleting temporary Internet Explorer files.

Occasionally, settings in Internet Explorer are changed that could affect the way Internet Explorer works. You can reset Internet Explorer to its default settings. Resetting Internet Explorer is irreversible. Therefore, you should check the list of settings that will be affected by the reset.

External factors affecting the connection speed

Unfortunately, there are events and conditions that are outside of your control. Even with a fast connection, external factors such as For example, congested websites or spreading computer viruses slow down the entire web. Popular websites can collapse due to a large number of visitor traffic. For example, many people may be trying to visit a website at the same time if it is mentioned in the television commercial. Delays can occur if the website is not prepared for traffic.

The internet can slow down during times of severe computer virus outbreaks. Many viruses spread by causing computers to send hundreds of thousands of copies of the virus. This can slow the internet down by its sheer bulk. You can see what major outbreaks are currently occurring by visiting your antivirus provider's website or the Security at Home website.

Local internet congestion can also result in slower-than-normal connection speeds. These slowdowns occur when many users are connecting to the Internet at the same time. This is especially true at peak times, e.g. B. when students surf the Internet at home after school.

If you are on a corporate network, general network and proxy server usage can affect your Internet performance. Most network administrators monitor Internet usage and try to prevent users from e.g. B. Download large files during peak hours. If you find that your Internet access is sometimes too slow, contact your network administrator.
