Team Fortress 2 will not launch. [RESOLVED]

[Fract]

Here is what I have ALREADY DONE:

- Restarted Steam
- Validated files (x3)
- Reinstalled TF2 (x2)
- Restarted Computer
- After uninstall, deleted any remaining files, then reinstalled (Fresh Install)
(Edited in)
- Antivirus is AVG, in previous years I have allowed TF2 to be allowed through my firewall

I do not have any custom files inside Team Fortress 2.
Yes, I have looked in the Discussions to try to find a solution.
The last time the game launched correctly was 2 days ago, I have not tried to launch the game again until recently. Then this started happening.

I have no idea what to try now. Any help would be greatly appreciated.

EDIT: ISSUE HAS BEEN RESOLVED:
- Temporarly disabled my antivirus, and it worked.

TF2 Won't Start

Either:

• Restart your device
  
  
• Reinstall TF2
  
  
• Verify your cache (Right click TF2 in your library > Properties > Local Files > Verify Integrity Of Local Game Cache)
  
  
• (Suggested By Dog)Check for any outdated and/or incompatible mods and delete or update and/or replace them
  
  or
  
  
• It's An Engine Error

According to what you said, you probably have an outdated file.

What does this mean?
If you are implying that there may be some incompatible mods within my Team Fortress 2 folder, that is not the case. My entire Team Fortres 2 folder is a fresh install, since I deleted ALL REMAINING FILES after a previous uninstall. There is NOTHING remaining from any previous mod. It is as if this was the first time installing Team Fortress 2 on a computer.

If you mean mods outside of Team Fortress 2, I would need an explanation as to why a non-TF2 related file would make Team Fortress 2 incompatible.

Thanks.

Oh true (sorry about that), forgot that when you reinstall completely you get fresh folders.
Really weird, there could be a chance that some program affecting TF2, I don't know exactly how they do this, but some do.

Uhh, what antivirus do you have? Check the quarantine and see if hl2.exe is in there.
Also I need to know the specs (Type of computer, OS, processor, graphics, RAM, etc.)

You fixed it?
