Steam is a popular digital distribution platform for purchasing and playing video games, but many users reported that conflict software was detected while running it. One of the errors reads like this:

An incompatible version of LavasoftTCPService.dll (related to Lavasoft Web Companion has been detected inside of the Steam process).

We suggest updating or uninstalling this software if you experience crashes or network slowdowns while running Steam or individual games.

Since many Steam users are facing this problem, we have put together this guide including all the possible solutions to fix this error on Windows computers.

What is a software-conflict error?

Because you need to be aware of any important detail implied in your issues, keep in mind that a software-conflict error occurs when two programs cannot run on the same PC at the same time.

In general terms, this kind of issue can appear due to a programming bug and typically manifests when two programs compete for the same resource (memory, peripheral device, register, etc.).

If you want to discover more about this kind of program, make sure you read this article completely, because at the end of it we’ve prepared some useful information.

How can I fix the conflict software detected Steam error?

  1. Uninstall conflicting software
  2. Run Windows Defender
  3. Run Antivirus software
  4. Reset network adapter

1. Uninstall conflicting software

  1. Hit the Windows key, type Control Panel, then open it.
  2. Now, click on Uninstall a program.
  3. Look for Lavasoft or any other software mentioned by the error message.
  4. Click on it, then choose to Uninstall it (as we show you in the picture below, with Twitch as an example).
  5. If you don’t find Lavasoft software in the Control Panel, look for any other related program like WEN Companion, etc.
  6. Click Uninstall and restart your PC.

The best guess here is that some software is creating a conflict with the Steam process resulting in the Conflict software detected message.

Depending on the error you get, try to find the mentioned software (like Lavasoft in the above example) and uninstall it.

A lot of software leave unwanted leftovers after you uninstall them and if you want to make sure you got rid of any Lavasoft remaining files.

You might thus consider other options to eliminate the issue of conflicting software and put your Steam services back on track. Hence, it’s feasible to check other efficient uninstaller software for Windows 10 PC.

2. Run Windows Defender

The conflict software detected error usually appears if you have junkware on your PC. Sometimes these unwanted applications can interfere with your system and lead to various problems.

Plus, by protecting your system with Windows Defender you can stay relaxed when browsing on different sites, or downloading certain programs, knowing you will be alerted.

What programs might interfere with Steam?

As we’ve already promised at the beginning of this guide, it is time to discover more about the programs that might interfere with the Steam app.

1. Antivirus, anti-spy software and firewall & security apps

This article already presented that antivirus software and security apps are some of the most popular elements that can generate conflict when running Steam.

Keep in mind that antivirus programs hook very deep into your system and can affect disk and network operations which will cause issues with Steam.

Aggressive spyware detection apps might also interfere with the Steam client from receiving updates or prevent connection to content servers.

2. VPNs

Some virtual private networks might also prevent your client from accessing the app’s network. If a game requires network capability, it may also interfere with that connection.

3. Peer-to-Peer (P2P) Clients & File Sharing Software

In this case, if not configured in a proper manner, you have to know that P2P clients consume a large portion of your bandwidth or other system resources.

This can limits connections or traffic that Steam depends on, while also interfering with resources required by games.

4. Download Accelerator and Download Manager Programs

These ones curate your network experience, so your Steam and game traffic may be hindered. You’ll probably also want to disable this kind of app while using Steam.
