Internal Error 2771 is an internal error code associated with Kaspersky Internet Security and Antivirus software. This error pops up when Kaspersky Internet Security software fails to install on your PC successfully.
Installation of the software is interrupted and therefore it ends prematurely. This happens mostly when you try to install a new build on an existing installation.
Internal Error 2771 is displayed in one of the following formats:
Internal Error 2771, Sandbox Feature
or
Internal Error 2771, WholeProduct Feature
Error CausesThis error may result on your computer screen due to several reasons. Some of the most common underlying causes include:
To successfully overcome this problem and ensure the successful installation of Kaspersky Internet Security software on your system, try the methods given below.
Sometimes Internal error code 2771 may appear during installation due to the leftover registry key from the previous Kaspersky software removal.
A registry key is often created when uninstalling the previous Kaspersky version from the PC. This key is left behind even after you reboot your system.
This key is called AVP**_post_ uninstall, you need to delete it to ensure the new version of the Kaspersky program is installed successfully on your PC. For this, simply go to the start menu and type Regedit in the search bar.
Now navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun and then look here for the registry key called AVP**_post_ uninstall. In order to delete this file, right-click it and then select delete.
Once uninstalled, reboot your PC and then try installing the Kaspersky Internet Security program again.
Hopefully, this will resolve the issue. If the software installs smoothly, then the error is fixed, in case it still persists, then try other methods illustrated below.
Another reason for the error pop-up may be INFCAHCHE.1 corruption.
This file is basically used to store driver information and inf file locations. However, if it contains corrupted information, then you must remove it.
To do this, go to the start menu and type cmd into the search bar. This will open a command prompt. Here type del C:\Windows\infinfcache.1. Now reboot your PC and try installing Kaspersky software on again.
Security software conflict can also result in internal error 2771 code display. And when this happens, the installation of Kaspersky prematurely ends.
Security software conflict may occur if you have Comodo Firewall installed on your PC. A firewall is known to cause issues with Kaspersky software programs.
The best way to resolve this issue is to uninstall all security software programs on your PC. Once all security software is removed, then install Kaspersky on your system. If the installation is successfully completed, then reinstall the other software again.
Error 2771 can also result on your computer screen if traces of the previously installed Kaspersky software still remain in the registry despite the program removal. In such an event it is advisable to download Restoro.

Error CausesAfraid of the growing threats online? As you should be. But we’re here to show you what kinds of malware are out there and what you can do to keep them at bay.
Malware comes from the term malicious software. It’s software designed to attack and exploit devices and networks to the advantage of the hacker who made it.
Malware can be transmitted in different ways. Most commonly this happens via infected USB drives, downloadable files or malicious websites. Depending on the type and ultimate goal, the consequences of a malware attack can range from negligible to catastrophic.

A virus is typically spread via infected files, websites or links. It’s one of the oldest malware types and one of the most difficult to get rid of. That’s because, once activated, it replicates itself - hence the name.
It can perform different kinds of attacks, depending on what the creator wants to achieve. The main characteristic of a virus is that it really doesn’t show itself until you activate the host. So that’s a scary thought for sure.
Sometimes an ad blocker isn’t enough to fight off unwanted ads. And some of them can, unfortunately, be malicious. They may redirect you to infected sites or prompt downloads of risky files. Even just opening a malicious site can lead to data theft.
So, definitely be careful when clicking around. Even if an ad seems completely legitimate, you can never be too sure.
Through ransomware, cybercriminals gain access to a user’s data and use it to extort them for money. Basically, the user is threatened with data deletion or even exposure if a ransom isn’t paid by a specific deadline.
This is a particularly nerve-wracking type of malware. If it targets an individual, it preys upon their sense of anxiety, fear, guilt and even shame. If it targets a business (which is a lot more common), it preys upon not only that business’s profit but also every single one of their customers and their data.
This type of malware disguises itself very well as a legitimate-looking program. Once you download it, hackers can get full access and control of your device, data and network. They can even be hidden in games, apps and attachments. They cannot self-replicate, though, so we guess that’s… good news?
Worms can replicate, just like viruses, but you don’t need to actually activate the infected program for them to get going. They can be used for various purposes, ranging from data deletion to file encryption to support a ransomware attack.

Spyware refers to malicious software that stays hidden on your computer and monitors your activity. The best-known type is keyloggers. This can be used to steal sensitive data like passwords and banking information.
Rootkits are among the most dangerous types of malware. They allow administrative access and full control of a device, which lets hackers continue hijacking all your data and monitoring your activity without your knowledge.
Botnets are networks made up of bots - computers that cybercriminals have infected with malicious software. Bots and botnets give hackers remote access to users’ devices and allow them to spy on your camera, take screenshots, memorize passwords and launch Distributed Denial of Service attacks. This one truly makes your hair stand on end.
You know the old adage - better safe than sorry. And trust us, malware attacks are such a pain in the you-know-what that you really don’t want to be sorry.
Luckily, there are simple solutions that can shield you from most digital threats these days. What you want to be looking at is a solid antivirus program. Well, technically, you need an antimalware program, but since the latter evolved from the former, we still mostly refer to them as antivirus software.
The majority of antimalware programs these days don’t just shield you from potential risks online, but include additional features as well. For example, some Bitdefender antivirus packages also include parental control and a VPN. And Bitdefender is not just for PCs either - it offers protection for your beloved iPhone or Android as well. You can throw in a password manager in there too, for an additional layer of security.

If you aren’t too concerned about all these various threats or feel like you don’t need extra security, you can at least take a step to protect your information from being exposed to lurking cybercriminals as you’re browsing. This can be done through a good VPN like Surfshark, which hides your identity in the digital space and prevents your data from being tracked.
Choosing the right protective software is especially important if you have children with access to the Internet, since they’re unfortunately even more vulnerable to malicious attacks. If you aren’t sure what the right kind of antimalware program is right for you, you can reach out to us and we’ll be happy to help keep your entire household or office digitally secure.
The truth is that there’s no way to be 100% protected in the online world. Hackers are constantly coming up with new ways to infiltrate our devices. But malware-battling software evolves along with them and there’s still plenty you can do to keep risks away. Stay safe!
