Web Shield is currently the most sophisticated security component of Avast Antivirus, and monitors all network activities. Web shield may slightly affect the speed of your internet activity, due to its high functionality, but the difference is generally imperceptible.
Internet speed tests may be affected while scanning for connection speed if Web Shield is enabled, as the test can confuse Web Shield activity speed with internet speed and local hardware.
Why is my high speed connection slower with Web Shield on?
High speed connections greater than 20Mbits/s may see noticeable delays under certain conditions while Web Shield is enabled. For example, if a hard drive has an I/O speed of 30Mbits/s, the Web Shield can decrease the loading speed of a webpage because the hard drive I/O operations are doubled during active scans. In this case, the internet input of 20Mbits/s combined with 20Mbits/s of Web scanner data output then exceeds the maximum hard drive ability and can lead to noticeable delays.
Are there specific devices that have compatibility issues with Web Shield?
Some network components or connection types may be incompatible with a parts of Avast Antivirus or Web Shield in particular, as the default setting for some routers and ADSL modems may expect a different connection or packet type. This mismatch can cause connection resets and timeouts. Web Shield scans may also cause a device to time out if the device has a short timeout setting.
Avast monitors reports regarding specific devices and contacts device vendors about frequent issues with proposed coding solutions or workarounds. However, many issues are related to specific settings within Web Shield and can be disabled without eliminating your protection.
Are there any workarounds to improve web performance when using Web Shield?
You can customize your Web Shield configuration or if absolutely necessary, disable some settings as workarounds for the web speed issue. These features can be disabled with only a minor impact on user security.
To adjust Web Shield settings:
- Open the Avast Antivirus user interface and go to
☰
Menu ▸ Settings ▸ Components. - On the Web Shield panel, click Customize.
- Manage these settings:
- In Main settings: Untick the box next to Use intelligent stream scanning to disable the setting. When enabled, intelligent stream scan continuously scans files while they are being downloaded. When disabled, it may increase your browsing speed, as downloaded files are scanned only after download . However, in rare cases unticking the box can slow down web browsing even more.
- In Main settings: Untick the box next to Enable HTTPS scanning to disable the setting. When enabled, the HTTPS scan protects your system against the malware delivered over HTTPS connections. When disabled, File Shield still scans all downloaded content before running any files.
- In Sensitivity: Set the Heuristic sensitivity bars to Off and untick Use code emulation to disable the settings. When enabled, Heuristics consume your PC resources to continuously analyze code for malware. When disabled, Web shield will consume fewer resources on your PC and speed up your web browsing, but may not detect malicious code.

Recently my computer has just gotten so slow. I downloaded CCleaner and along with it came Avast. The former I ran and got rid of a bunch of junk slowing down my computer, but it was still slow so I decided to use Avast. I ran the Cleanup Premium test and under Programs slowing down your PC - this is what it detected:
I checked online and it seems that 'Digital TV Tuner device registration application' belongs to Windows Media Center and it enables you to watch cable TV.
According to Avast, it's slowing down my laptop by 72%. I tried to uninstall Windows Media Center via the control panel but I could not find it there. Is there any way to safely remove it or fix this issue?

If your computer is legitimately slow and you actually want to fix it, learn how to diagnose problems based on the actual indicators of performance issues, which you can find built into the system.
Windows' Resource Monitor tool is something that every user should be familiar with. To start it, first open Task Manager (Ctrl+Alt+Delete -> Task Manager). In Task Manager, click on the Performance tab, then click 'Open Resource Monitor' at the bottom.
The three tabs you'll mainly be concerned with are:
- CPU,
- Memory,
- Disk.
Basically you want to look for processes that are consuming huge amounts of one or more of these resources. These are the processes that are slowing down your computer.
If no particular process jumps out at you as consuming huge resources by itself, you might just have too many programs installed at once for the resources you have available on your system. If this is the case, you'll need to either uninstall some programs and live without them, or close them (including any background processes they might keep running when you close the window), or upgrade your system with better components, or as a last resort, get a new system.
Don't rely on shiny shrinkwrapped programs to tell you what's slow based on some heuristic. Most often they are not very accurate. Instead, dig down into the raw data and diagnose it yourself. Then figure out what program the offending process is related to, and either temporarily kill, uninstall, or delete the offending program.

just go to add/remove programs, select turn windows features on or off and scroll to media features then un-tick media center (unless you use it) as it is part of media center :)

Unneeded programs may be slowing your computer down, so take a look at how many programs you use and how often you use them, says Molnar. (Photo by Katelin Kinney)
Enter a zip below and get matched to top-rated pros near you.
Whether you use a PC or Mac, everyone’s computer slows down eventually. One highly rated provider shares 10 reasons your computer may be slowing down.
Whether you use a PC or Mac, everyone’s computer slows down eventually. Here are a 10 possible reasons your machine isn’t running as fast as it used to, and how you can fix the problem.
1. Too much in the trash bin.
You can never underestimate how important it is to take out the trash. When you delete files, they aren’t immediately wiped from your hard drive. It puts them in holding area of the hard drive. They are left there and not deleted so that they can be restored, just in case they were deleted by mistake.
You always want to check the contents for anything important before you empty it. Emptying your recycle bin can speed up the computer's performance and add room to your hard drive.
2. A dirty desktop.
A cluttered desktop makes things disorganized and hard to find, but it can also slow computers down. The purpose of the desktop is to be interactive, not to store files. Its job is makes it easy for you to navigate your computer and give you information.
If you have a large amount of files on your desktop, it is slowing down your computer. Those files need to be reorganized in your other folders. If you have multiple widgets running on your desktop or dashboard, they could be slowing your computer down also.
3. Too much in cache.
Caches helps make things faster and easier to get to, but too much in your cache could be slowing your computer down. The same goes for temporary Internet files.
If you do a lot of web browsing, this is probably the main reason your computer is slow. In Windows, close all the Internet browsers, open up “Internet Options” and click delete in the “Browsing History” section.
4. Old software.
Keeping your computer updated could be a greater part of its health than you think. When companies update the software, this software is meant to work better with your operating system.
You want to make sure your hardware, your operating system, and your software are all on the same page. Sometimes new updates have bug fixes that can improve the overall operating speed of your computer.
5. Too many programs.
Unneeded programs may be slowing your computer down. Take a look at how many programs you use and how often you use them. The more programs you have, the more connections they make to your OS, and the more it bogs down your computer.
When you remove them, make sure they are fully uninstalled. Fallout 4 gameplay overhaul. Application leftovers can use up a lot of space and slow your system down. If you have a Mac, “AppCleaner” is a great application to make sure you have all the corresponding files deleted.
6. Too little space.
Because of the way “Virtual Memory” works, RAM files get swapped out onto the hard disk. If the hard disk doesn’t have very much space, it will slow the process down. If your computer has less than 10 percent of the total hard drive space free, it will begin to slow down.
7. Too many fragments.
Fragmented data can cause the read/write function of your hard drive to slow down. Set up a schedule to defragment your hard disk regularly. In Mac OS X, it is also helpful to verify and repair the disk and disk permissions.
8. RAM.
A computer’s RAM makes all the difference in the world. It can determine a great deal regarding the speed of your computer. If you have made other improvements to speed up your computer and it doesn’t seem to make a difference, your RAM may be the problem.
First, try resetting it. On a Mac, hold down command-option-P-R right after it’s powered on. It should go black and restart normally, but a whole lot faster. Windows users will have to download a program like “RAM Def 2.6 Xtreme” to reset your RAM.
If resetting it doesn’t work, you will need to buy more RAM. Check with the machine’s manufacturer and the tech specs to make sure what you intend to get is compatible with your machine.
9. Bad fonts.
Not all fonts are good. Fonts downloaded from the web could be fine, but some are bad. Font errors can slow down your computer. Make sure all of your fonts are valid, as some of them may be harming your computer.
10. Too many processes.
Computers can slow down from low CPU performance. Check what processes are running, as some of them may not be needed. Editing the startup items can also speed up your computer.
You can do many other things to speed up your computer, but try these first. They may work for you.
