Although Avast antivirus is one of the lightest on system resources which was confirmed in various independent tests, you can make it even more faster by adjusting a few settings. Some users also reported Avast is actually slowing down their computer or Internet connection. This guide will tell you how to increase/boost your system (Windows) performance and startup time with Avast antivirus 2017 installed.
These simple tips will decrease the boot-time and increase the performance of your computer running on Windows 10, 8.1, 8, 7, Vista and XP. No matter what Avast solution you are using (Free Antivirus, Pro Antivirus, Internet Security or Premier).
1. Improve Your Computer Startup (Boot) Time by Loading Avast After Windows Services
This is a perfect solution if your computer (Windows) is starting very slow. By loading Avast services after system services you will basically turn on Avast after everything else in Windows is loaded. That will speed-up the Windows boot time but on the other hand there are also security risks because your system won’t be fully protected for a few seconds.
1.1 If you still want to try this just open your main interface and go to settings (last item in the left menu). Find menu item ‘Troubleshooting‘ and there is an option ‘Load Avast services only after loading other system services‘. By default it’s un-checked, so you have to just check it.

1.2 We suggest to test if this change got any notable impact on your computer boot time. If not, it’s better and more secure, to leave this option un-checked. Interesting is that this change doesn’t affect the protection status as the one below (you will still have a green one). But it’s definitely more dangerous in terms of security.
2. Improve Performance of Your Computer by Postponing Background Updates
Most of the Avast users know this story. When you need to turn on your computer and want to just quickly check something online. But what happens, Avast antivirus starts downloading the latest virus database update on background and everything seems to take ‘ages’. This can also happen when you are playing your favorite game and every FPS (frame per second) counts. Luckily there is a simple way how to disable these ‘startup’ updates and increase the performance of your computer after startup.
2.1 Open the main program interface and go to settings (last item in the left menu). There look for section ‘Update‘ and expand ‘Settings‘ in ‘VIRUS DEFINITIONS‘ tab. There are settings of how would you like your Avast to download the virus definitions – a) automatically; b) ask when available; c) manually.

2.2 By default option a) is selected which is causing the inconvenient background updates. So we suggest to choose option b) and have full control over when the update will be downloaded. You can keep streaming updates enabled, as they are very small and doesn’t slow your computer at all.
Every time the new virus definitions update will be available, you will get a following pop-up notification. To update the database simply click on ‘Update now‘. We definitely recommend to update your virus definitions as soon as possible.

2.3 However you have to note there is a low security risk related to this as you won’t always have the latest virus definitions in your Avast antivirus. Also it will change the green background on the main window to the yellow one as shown on the image below. Now your computer should run much faster after start-up. To turn on automatic updated simply click on ‘Turn on‘.
2.4 If you don’t like the ‘ATTENTION’ message on yellow background, you can adjust the settings and make it ‘YOU ARE PROTECTED’ again. Even if you have automatic virus definitions updates turned off and/or outdated virus definitions. Simply click on ‘IGNORE’ below the warning message and you shouldn’t see it again.
3. Other Performance and Speed Up Tips
3.1 Opt-out from Avast community and data sharing by going to settings » ‘General‘ » ‘Privacy‘ » un-check ‘Participate in the Avast community‘ and ‘Participate in data sharing‘. This means Avast won’t collect any data or information about your online behavior.
3.2 If you are not using any desktop e-mail client like Outlook or Thunderbird, feel free to disable the Mail Shield completely as it doesn’t work with online mails like Gmail or Yahoo!. Go to settings » ‘Components‘ » switch Mail Shield to ‘OFF‘ state by click on the switch and selecting ‘Stop permanently‘. Alternatively you can remove the whole Mail Shiled component from your computer (see 3.5).
3.3 Disable Software Update, Browser Cleanup and Cleanup background scans and pop-ups by going to settings » ‘Components’ » ‘Customize‘ and un-check ‘Enable Software Updater‘ for Software Update; ‘Check my browsers regularly for toolbars with bad user rating‘ for Browser Cleanup; ‘Always test this computer for performance issues‘ for Cleanup.
3.4Disable Remote Assistance, unless you are regularly using it of course. Go to settings » ‘Tools‘ » and change the switch for Remote Assistance to ‘OFF‘ state. Then go to ‘Troubleshooting‘ » and un-check ‘Allow remote control of this computer‘.
Removing Unused Avast 2017 Components and Tools to Increase Computer Performance and Speed Up
3.5Remove any Avast tool/component you are not using. Go to Programs in Windows » Uninstall or change programs » select Avast and click on ‘Change‘. Once the Avast setup window will appear click on ‘Change‘ and un-check component you would like to remove. If you are looking for the pure Avast antivirus protection, you can basically deselect everything besides the shields and even a Mail Shield if you are not using desktop e-mail client.
3.6 Invest $20 a year and buy Avast Cleanup. Our last tip is actually not free, but we still believe it’s worthy. Avast Cleanup is the PC optimization and speed up tool which will keep your computer in a great shape by optimizing the system settings, cleaning the useless file and apps, and fixing registry issues.

I'm guessing that it's a trial version as I haven't paid for anything. The product I have is called AVG AntiVirus Free and this is an AVG Protection scan

DismissAsk a question by Martin Brinkmann on May 25, 2018 in Windows - 29 comments
Some Avast antivirus users reported a blank desktop with no icons or interface elements issue or a 'boot to choose your keyboard layout' screen when they ran the upgrade from earlier versions of Windows 10 to the latest version Windows 10 version 1803 that Microsoft released on April 30, 2018.
Microsoft acknowledged the issue on May 24, 2018 on the company's consumer forum but did not link it explicitly to Avast or other antivirus or security software running on devices.
Avast published an update for affected products yesterday that resolves the issue according to the company. According to the information, the issues were caused by incompatibilities between Windows 10 version 1803 and Avast's Behavioral Shield module.
In cooperation with Microsoft we have identified an element of the latest Windows 10 1803 update that is incompatible with the Avast Behavior Shield, causing the aforementioned update to fail in some instances (related to a timing issue, Internet connectivity issue, etc).
Avast and Microsoft identified the issue which allowed Avast to fix the issue.
Luckily, we have found a way to prevent the problem and are now automatically pushing a VPS update to all customers which makes sure that the problem doesn't happen. The VPS number is 180524-08; all users running this version (or later) should be 100% safe.
Avast users who run earlier versions of Windows 10 are encouraged to update the application to the latest version before they try to upgrade the machine to the new version of Windows 10.
You can run update checks in the following way:
- Open the interface of the Avast product that you are using, e.g. Avast Free Antivirus.
- Select Menu > Settings.
- Go to Update.
- Select all update buttons on the screen, e.g. for Virus definitions and for Program.
The update should resolve any blank desktop or select keyboard layout issue that may be experienced without it.
Note: We recommend that you create a backup of the system before you run the upgrade just in case. A backup allows you to go back to the previous version of Windows without having to rely on Windows' own rollback functionality which does not work all the time. You could also uninstall Avast before you run the upgrade and reinstall the software after the upgrade completed successfully.
Avast published instructions for customers that tried the upgrade already and face a blue screen or other issues caused by the incompatibility.
Check out this post for instructions. Note that it requires that you still have access to a functioning PC as you are asked to download Windows 10 installation media which you need to resolve the issue. (via Deskmodder)
Now You: where you affected by any bug recently introduced by Windows updates?
