If you’re playing Roblox and suddenly see a popup from Kaspersky Internet Security blocking something, it’s not a glitch it’s your antivirus doing its job. But that doesn’t mean you have to stop playing. Learning how to handle these popups correctly keeps Roblox running smoothly without leaving your system exposed.

Why does Kaspersky block Roblox in the first place?

Kaspersky scans network activity and file behavior in real time. When Roblox tries to connect to its servers or download game assets, Kaspersky may flag it as suspicious especially if the connection uses unusual ports or downloads unsigned scripts. This is common with games that update frequently or use peer-to-peer features.

What should you do when the popup appears?

The popup usually gives you two choices: “Allow” or “Block.” Don’t just click “Allow” blindly. First, check what exactly is being blocked. Is it robloxplayer.exe? A specific IP address? Or an SSL certificate issue? Knowing this helps you decide whether to trust it.

If you’re unsure, you can temporarily pause real-time scanning to test if the game runs but only for a short time. You’ll find steps for that here, along with how to turn protection back on afterward.

How to add Roblox as a trusted exception

Instead of clicking “Allow” every time, tell Kaspersky to trust Roblox permanently. Open Kaspersky > Settings > Additional > Threats and Exclusions > Manage exclusions. Add these paths:

  • C:\Users\[YourUsername]\AppData\Local\Roblox
  • C:\Program Files (x86)\Roblox

You can also exclude robloxplayer.exe specifically. Just make sure you’re excluding the official Roblox files not random .exe files downloaded from third-party sites.

What if the popup keeps coming back after adding exceptions?

Sometimes, even after adding exclusions, Kaspersky still interferes. That’s often because the firewall is blocking Roblox’s network ports. You might need to adjust port settings so Roblox can communicate freely. A walkthrough for that is available in this guide.

Is it safe to allow Roblox through Kaspersky?

Yes if you downloaded Roblox from the official site or app store. Roblox is digitally signed and widely used. But if you’re getting popups about unknown scripts or .dll files inside your Roblox folder, that’s a red flag. Malware sometimes hides there. Run a full scan before adding any exceptions.

SSL certificate errors? That’s different

If Kaspersky blocks Roblox because of an SSL warning, it’s likely intercepting secure connections for scanning. Some users fix this by disabling HTTPS inspection for Roblox domains. More details on handling certificate-related blocks are explained here.

Common mistakes people make

  • Clicking “Allow” without reading what’s being allowed
  • Disabling the entire antivirus instead of just adding an exception
  • Adding exclusions for the wrong file path
  • Forgetting to re-enable protection after testing

Quick checklist before you proceed

  • Verify Roblox was downloaded from roblox.com or official app stores
  • Note the exact file or process Kaspersky is flagging
  • Add exclusions only for verified Roblox folders and executables
  • Check firewall rules if connection issues persist
  • Re-enable full protection after troubleshooting
