Steam Fatal Error

[arao]

I am having problem with Steam Client for a few weeks. I have tried many of the solutions. First it shows error code-130. Then I uninstall Steam. When I install again it and tried to run Steam it shows "Steam - Fatal Error" dialogue box.
I have tried the following steps.
1. Run Steam Client as administrator.
2. LAN Setting solution.
3. Uninstalling software which can affect on Steam like BitTorrent, Driver Booster, Proxy Switcher.( I have uninstalled all of the Driver Booster related services like Scheduler)

For antivirus I have Kaspersky. I didn't use Windows Defender and Windows Firewall.
I made a few changes in Kaspersky like putting Steam in exclusion. Noting seems to work.
I connect Internet from my phone through tethering or hotspot or EV-DO data card.
I have done System Restore but it didn't work. I want to hear suggestion or solutions from you guys.

Kaspersky is on the list of known programs konwn to interfer with Steam.
Try whitelisting Steam and its folders.
If that doesn't help, try uninstalling Kaspersky temporarily.

I have uninstalled Kaspersky. Still it didn't work. Formatting my laptop is the last thing I want to do.

Your Steam Client is most likely trying to update itself, but blocked in doing so (this could be file writing, file lock, or downloading issue for the client)...

Exit Steam.

Delete all of the files in the steam folder except:
- \Steamapps\ folder (which contains your games)
- Steam.exe (to be able to run it)

Right-click the "Steam.exe" and select "Run as Admin". It will attempt to redownload those removed files again.

Under your Kaspersky, check under "More Tools" > "Application Control" and set all the Steam files to "Trusted" (right-click them > restriction > trusted).

Check under it's "Network activity", for "Steam Client Bootstrapper" and "Steam Client WebHelper". Right-click and select "Application Network Rules", ensure they are allowed.

Also, ensure you have enough free disk space, the files aren't locked/restricted (ensure you are on an admin account) and your internet ports required for steam isn't being blocked by router (or another firewall).

Required Ports: https://support.steampowered.com/kb_article.php?ref=8571-GLVN-8711

Kaspersky Internet Security (and other Kaspersky products) have no issues with Steam, if not blocked on purpose. I personally use it myself and it's a fine application to use. (the ones with the green star next to them, they only recommend removal, but at least you can rule it out)

It was fine a few weeks before. Tried your steps it didn't work.
