What is your antivirus program ? Sometimes, conflicting software can cause this problem. See this :

Yea, McAfee is a huge suspect to your problems. That is a terrible antivirus to use with Steam and games. It even has background processes that cause issues, other than the antivirus itself.

You can see them in msconfig, running that process from Windows Start. Those McAfee processes are poison for Steam and games, for many users.

Click on that and allow it to load the results. Go through the threads and see if you can find anything that might help you also. Often, the forum search, for this type of error, can be the best source of help to your problem.

You are welcome. To further show you just how bad McAfee can be for Steam, it can take a special "tool" to fully clean from your system. It does not even like to be uninstalled normally.

McAfee Product Removal Tool

The user has to go through all that nonsense to fully get rid of it.

If you absolutely must keep McAfee, you need to be SURE it is totally leaving Steam and games alone in real-time scanning, and check msconfig from Windows Start and see the services tab there. You will surely see those other processes I am speaking of.


EDIT......................

Also, I totally missed it above. Did you just say you have both McAfee AND Avast ?

That is another issue. You can't have more than one antivirus on your PC. That can cause all kinds of problems. They can even conflict with each other.

i should remove mcAfee and just keep avast?

That is what I would suggest, yes. And then you need to make sure Avast is leaving Steam and games alone in real time.

Any and all security processes need to be totally ignoring Steam and games in real-time scanning. And there can still be other software that can cause problems with Steam or games, but security programs and processes are very important ones to make sure are not.

ok so it says that the antivirus for avast is expired

So it was a trial basis and now expired then ?

You can have free versions of many antivirus programs also, if you wish. What antivirus you have is up to you. It just needs to be leaving Steam and games alone in real time.

Yea, exactly. They will do that, if they are not ignoring Steam.

And sadly, even after you resolve all software conflicts (yes, you might have others. we have not even explored that yet), then there may be even more steps to take.

For example, you might have to fix any damage all those processes may have caused.

Sometimes this is as easy as reinstalling Steam over the existing path, but DO NOT uninstall Steam first, if you do this.

Again, you have to resolve all software conflicts first, and foremost.

Then, feel free to see this, and I have to check back on the thread tomorrow, but other may post to try to help you further :

Reinstall Steam

The Steam installer can be downloaded here: http://store.steampowered.com/about/ and reinstalled to the same location where it is already installed.

This may fix potential issues with Steam client and service files. Installing into same location will preserve all installed games.

WARNING! Uninstalling Steam through any other method will delete all game and userdata content.
