Getting AVAST alert during program update/upgrade in Kali Linux

Kali Linux contains a ton of malicious tools, so it's expected that antivirus software complains about them. This can happen if it scans the network traffic during upgrade, which is probably the case now, as the upgrade uses plain HTTP connections. Some antivirus software might also scan the disk images of virtual machines. Both may cause problems to or break your Kali installation, so it might be a good idea to add some exceptions.

Despite technically malware, these aren't a security problem per se, but they are powerful tools that may cause problems if you don't use them wisely. You might end up weakening your security if you attack against your host machine.

As cybercrimes become more prevalent and more damaging, it’s important to be proactive to protect your devices. One of the best ways to do that is by installing an antivirus program. There are lots of these to choose from. Most will give you the protection that you need to use your devices safely.

But you might have problems with your antivirus software from time to time. For example, maybe you have Avast antivirus. If so, you could run into an issue where Avast AV Service stops responding.

If Avast AV Service stops responding, you need to start by changing your remote desktop services startup type to automatic. If that doesn’t work, try repairing the Avast application on your PC. If the problem persists, you may have to uninstall and reinstall the Avast application entirely.

What is Avast AV Service?

Avast AV Service is an antivirus program that’s designed to keep your computer safe. Avast is a cybersecurity company that specializes in antivirus software. The company’s AV Service should protect you from various types of malware. This is a list that includes viruses, spyware, adware, malware, ransomware, and more.

But in order for Avast AV Service to do its job, it needs to be working properly. If you’re getting an “Avast AV Service is Not Responding” error, then that’s not happening. You can keep reading to learn what might be causing the problem and how to fix it.

What is Avast UI?

Let’s start with a quick overview of how Avast works. Users access the antivirus program through an application. This is sometimes called Avast UI. When you open up Avast UI, you should be able to control how the software interacts with your computer.

But sometimes Avast UI can run into problems as well. Some of the most common Avast UI problems and their solutions are covered in the sections below.

How do I fix Avast UI failed to load?

Avast UI failed to load is one of the more common UI errors for Avast. This can happen for a few different reasons. But generally, it means that a module in Windows is interfering with the antivirus software. Or, it could mean that you have a corrupted installation file.

The first thing you should to do try and fix the problem is enable remote desktop service. Make sure that it’s set to run as automatic. Once you’ve made that change, closeout of the remote desktop service, restart your system, and reopen Avast. This could solve your problem completely.

But if that doesn’t work, you may need to reinstall Avast Antivirus. This is typically necessary if there are Avast files on your computer that are corrupted or improperly installed. Instructions for how to do this are included in the next section.

How do I reinstall Avast Antivirus?

Reinstalling Avast Antivirus is a fairly straightforward process. The first thing you need to do is uninstall Avast from your computer. To do that, you need to download the Avast uninstall utility from the Avast official website.

Once that’s done, reboot your system in safe mode. Then, run the Avast uninstall utility. Follow the prompts that appear on your screen to remove Avast from your system. The process should be self-explanatory once you begin it.

Next, you need to reboot your system and redownload Avast from the company’s website. Make sure that you’re logged in as an administrator so you don’t run into any problems while doing this.

The installation process should be pretty straightforward, especially if you’ve already done it in the past. Simply follow the on-screen instructions and prompts until you’re finished. Completing this process can help you resolve a wide variety of Avast AV Service problems.

Why will Avast not open?

Another common problem with Avast is the program simply not opening up on your device. This can be annoying to deal with. But the good news is that the fix for it is pretty easy. The most common solution is to repair the software. Don’t worry if you’re not sure how to do that. Here are instructions for the process.

Begin by clicking the start button on your PC. Then, type “control panel” into the search bar. The Control Panel icon should pop up for you. Click “launch” when you see it.

Next, navigate to Programs. Then click on the button that says “Uninstall a Program”. Don’t worry, we won’t actually be uninstalling Avast during this process.

Here, you should see a list of the programs on your PC. Scroll down until you find the Avast file. Click on it once so that it’s highlighted. Then click on the “Repair” button at the top of the menu.

Once this process is complete, you should try restarting your computer. There’s a good chance that the problem will be fixed after you reboot.

Avast Antivirus won’t update

This can be a very frustrating issue to deal with. You need your antivirus software to update so that it can detect the latest types of malware. If you’re experiencing this problem, then there are a few different fixes that you can try.

First, make sure that your operating system is updated to the latest edition. You can do that by going into your PC’s settings. Then click on “Update & Security”, “Windows”, and “Updates”. Once there, you’ll find a button that says “Check for Updates”. Click it and install any updates that are available to you.

Another solution is to try temporarily disabling your firewall or VPN. These can sometimes interfere with Avast’s auto-update feature. You can do this by clicking “Start”, then type “firewall” in the search bar that pops up. 

Next, double click on “Windows Firewall”. Click on the option that says “Turn Windows Firewall on and off”. Then click on “turn off firewall protection”. You can try updating Avast again after this and see if it works.

Avast Causes Black Screen in Windows 10

This is another issue that you might encounter while using Avast on a Windows 10 device. If you’re experiencing the problem, then here’s a solution that you can try.

Start by opening up your Avast UI. Then go to the settings tab and click on general. Here, you’ll see a tab called “exclusions”. Click on it. Then add this address to the exclusions list “C:WindowsExplorer.exe”. 

Add this one as well, “C:WindowsImmersiveControlPanelSystemSettings.exe”.

Once you’ve done that, save your changes and restart your computer. This should resolve the black screen problem that you’ve been having.

Is my Avast working?

It can sometimes be a challenge to know whether or not your Avast antivirus is working. If you’re not sure, then you should look out for one of these signs.

First, try navigating to the main Avast application screen. Once there, do you see a red status? For example, you might see the phrase “Firewall is turned off” in red letters. If you see something like this or another message, your Avast isn’t working.

You can also take a look at the Avast Antivirus icon in the taskbar from time to time. This will update when the program stops working. If your Avast isn’t working, you will see a message that says, “You are unprotected”.

Finally, another sign that Avast isn’t working is if you can’t find the app on your device. It’s possible that it was inadvertently deleted from your PC if this happens. Similarly, if you can’t open the application, then it’s likely not working properly.

But if you don’t see any of these issues, then Avast is very likely working as intended. So you would have nothing to worry about in that scenario.

How can I activate my Avast Antivirus?

You need to activate Avast Antivirus before it will start protecting your computer. Doing this is a pretty simple process.

To start, make sure that you have the latest version of Avast installed on your device. Then, open up the user interface and go to the menu. From there, you should see a “sign-in” option. Click on it.

Once you’re here, you should go ahead and enter your Avast security credentials. Then click the sign-in button to complete the process. Finish up by clicking “continue” to complete the activation process.
