Windows Explorer and Internet Explorer won't run

Hey all

Windows 2000 sp4 +all other updates to date
256MB memory
Dell Optiplex GX150

After installing sp4 and rebooting, the comp was working fine. Shutdown the machine. My bro logged on, used the comp, it was working fine. He logged off. I logged on and then the explorer taskbar flashes and the disapears.

Now neither his account nor mine is getting explorer to run. I even tried creating a new account and that did not work either.

There is no desktop and if I try to run explorer from the task manager it just flashes the task bar and terminates. Internet explorer won't run either from the task manager.

All other applications seem to run fine and I can use the computer otherwise.

I tried renaming the shdocvw.dll file to .old but that did not help. That's all i tried so far from seaching the net.

Any help thanks.

Safe mode? Command prompt?

In reply to: Windows Explorer and Internet Explorer won't run

Try the last known good config as well.

Just FYI, no mention of what firewall you use and other nasties prevention tools. The damage is consistent with what I'm running into but repairs are not always the same. Sometimes I get to do a parallel install to remove a nasty item, sometimes a safe mode boot and SFC /SCANNOW works.

Best of luck in recovery.

What do you do to detect rootkits and examine HIJACKTHIS reports?

I tried...

In reply to: What about ...

I tried the safe mode thing and i still get a flashing tasking bar.

But what in the world is "detect rootkits and examine HIJACKTHIS reports?"

Any other help.
Or do I have format and einstall the whole OS.

RootkitRevealer by sysintenals shows I have (how to remove?)

In reply to: (NT) Oh now I see what rootkits are (I used google)

I have some and the discription says

Windows API length not consistent with raw hive data.
Data mismatch between Windows API and raw hive data
Data mismatch between Windows API and raw hive data

how do I remove these.

but how is it that this is the first time that I am hearing about rootkits. I mean there is so much hype about spyware that practically everyone including my grandparents knows about them. I have never read any articles before about rootkits. They see to be a greater threat.

May be fine.

In reply to: RootkitRevealer by sysintenals shows I have (how to remove?)

From memory that's a common entry or "false positive." The tools are not filtering the findings yet since it's still in the beginning stages of development. You can't filter since a rootkit could use that to hide.

Keep looking.


PS. Google that message since it may also appear as a result of Registry values that change during a scan.

They all reference Mc Afee I think

In reply to: May be fine.

the reg keys point to
\On Acess Scanner\Mc Shield\szLastSanned
\On Acess Scanner\Mc Shield\dwFilesSanned
\On Acess Scanner\Mc Shield\szLastModified

Very common if...

In reply to: They all reference Mc Afee I think

The other program was active at the time.

In reply to: I tried...

Safe Mode and Last Known Good fail, you are looking at trying a REPAIR INSTALL or a PARALLEL INSTALL to attempt the rescue.

Since you don't know what a rootkit is, please read this link and GOOGLE more about them. The detection kits are still free ->

The same story for HIJACKTHIS. If you type HIJACKTHIS into, you get most of your answer. I consider this place to not be "tech support" but a forum where we learn to learn.

-> I rarely have to reinstall the entire OS unless the damage ran so deep that it takes less time to reinstall and then restore from backups.

2 things.

In reply to: Windows Explorer and Internet Explorer won't run

1. Since you can run "things', try running SFC /SCANNOW

2. What's in the EVENT VIEWER?

Accoding to UnkackMe I have HackerDefender100

In reply to: 2 things.

should go ahead and remove this.

I had cleared the event viewer and rebooted but had no luck.

Some find...

In reply to: Accoding to UnkackMe I have HackerDefender100

Removing McAfee, ZA, Hackme or other items clear it up.

Since you are not responding to my queries in full, I can't offer much more. No note about how SFC /SCANNOW turned out, etc.

Sorry for that

In reply to: Some find...

sfc scannow did not yield any help either.
It ran fine but did not solve the problem.

Collapse -
Then keep at it.

In reply to: Sorry for that

Keep an eye on all 3 areas of Event Viewer for a clue.
