As I was playing a game on Pogo using Firefox the game suddenly crashed and everything was suddenly frozen. So I rebooted the computer and now my Avast antivirus program isn't operating properly and I have no sound plus it took about 3 minutes for Windows to finish loading all my startup programs which is only Avast Spybot S&D Teatimer and Yahoo Messenger. And for a while now Windows explorer crashes everytime I try to open a folder or my computer which forces me to reboot. I ran Spybot S&D and it didn't help at all. What do I do?

The 017 entry does concern me. What is that?

Turn Off TeaTimer, it can interfere with fixes done.

* Run Spybot-S&D in Advanced Mode
* If it is not already set to do this, go to the Mode menu
select
Advanced Mode
* On the left hand side, click on Tools
* Then click on the Resident icon in the list
* Uncheck
Resident TeaTimer
and OK any prompts.
* Restart your computer

Now, can I ask, what all do you have disabled from auto start? Go back into msconfig and put a check mark in Normal Start and then reboot.
Can you go back into msconfig and re-enable everything? We need to know what's on there.

Well this may seem short but the only items that actually appear on the list right now are...

ashDisp (Avast)
Yahoo! Messenger

So...I don't think rebooting would do any good.

Not just in start up programs also in services.

SBC Internet Services, is that your internet provider?

Yes my ISP is SBC Yahoo!

These are all of the services I have checkmarked at the moment.

Ok. Just wondered as I seldom see so few auto starts unless the scan is run in safe mode...
Really don't see much out of the ordinary in the log other than the small number of auto starts. Is there a reason you have never updated your browser to IE7?
How much RAM do you have on the system?
You say you ran Spybot, did it find anything and if so, what?

Do the following;
Please download Malwarebytes' Anti-Malware (MBA-M) to your Desktop.

* DoubleClick mbam-setup.exe and follow the prompts to install MBA-M.
* Be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform full scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When MBA-M finishes, Notepad will open with the log. Please save it where you can find it easily. The log can also be opened by going to Start > All Programs > Malwarebytes' Anti-Malware > Logs > log-date.txt.

Reboot the computer.
Run a new scan with HJT after the reboot and save the log.
Post back here with both of those logs.

Is there a reason you have never updated your browser to IE7?

Because I use Firefox. Should I bother to update IE?

How much RAM do you have on the system?

Right now 1024MB

You say you ran Spybot, did it find anything and if so, what?

It found one thing but it effected nothing really.

What did spybot find?

What did spybot find?

I don't remember now, but here are the results of the scan and the new log. Every problem seems to be resolved now but the WE one, I doubled clicked Recycle Bin and still get the error message.

What is the full error message you get? Have you checked Event Viewer for noted items around the time of these crashes? It should tell you quite possibly what is actually causing these crashes. I would need the full info on any of the noted items.
