PC very slow and freezing HELP!

[kristins1877]

Hi, for the past 6 months my Dell Dimension 3000 has been running fine. For the past 2 weeks it has been very slow opening programs and freezes after about 30 minutes. I have run AdAware Pro, Windows Defender, SpyBot, Norton AV and nothing is comming up. I took my case off, vacuumed all the dust and cleared the fans from dust. Installed EVEREST and PC temp is 25C and 77F. PLease HELP! I am OK with software applications but please walk me through techical stuff if you can recommend something.

THANK YOU!!!

Hi and welcome to techspot. Have you cleaned your system latelY? Please download ccleaner at ccleaner.com . Run that program and see if it helps.

 

[kristins1877]

I will try it now....

 

[akaivan]

ok keep me posted

Sounds like you have some ilk on your PC, i highly doubt ccleaner will take care of everything. (although it is a nice little app)

My friend howard has a good set of solutions.

Follow his instructions exactly, and whatever junk yo have on your PC will be gone.

What your describing sounds like classic spyware symptoms,although you say
you can`t find anything.

These two links cover most of the bases,also links to other great sites.

Update

OK, I ran ccleaner. It found and cleaned a bunch of junk, temp files, cookies, etc, but it did not solve the prob. I tried to run several of the other programs recommended but only 1 would work properly and completed the scan - ewido which cleared 7 adware stuff - but still not the problem as I am still freezing. Thanks for the great sites to clean up but any other suggestions? I am afraid that I will have to reformat which I definately do NOT want to do!! Is my PC running to hot? Also, I defraged to no avail.

Hello and welcome to Techspot.

Follow all the instructions in the link AtK SpAdE gave you, then post your HJT log here.

I will move this thread to the security and the web forum.

Regards Howard :wave: :wave:

OK as soon as I tried to run the links again I got a blue screen and the following message:

C000021a fatal system error
Windows logon process system process terminated unexpectedly with a status of 0xc000000s The system has been shut down.

When a started up again I got:
winlog.exe encountered a problem and needs to close.

I will try to run the link again (fingers crossed).....

 

[howard_hopkinso]

winlog.exe is a nasty piece of malware.

Follow these instructions.

Boot into safe mode. See how HERE. http://www.bleepingcomputer.com/forums/tutorial61.html

Turn off system restore.(XP/ME only) See how HERE. http://www.bleepingcomputer.com/forums/tutorial56.html

In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how HERE. http://www.bleepingcomputer.com/forums/tutorial62.html

Now do a complete virus scan of your computer and run all your antispyware tools. Then see if you can follow the instructions in the link Atk spade gave you.

Let me know if this helps.

Regards Howard

 

[kristins1877]

OK, I CANNOT boot into safe mode. I am able to enter my Administrator password and I get a black screen that says safe mode on the bottom. I tried several times and I can't get past that screen. I tried to run the antispy tools given in regular mode and pc shuts down with fatal error message again. Is there an alternative way to get to safe mode? (probably a dumb question....)

 

[howard_hopkinso]

The only way I know of getting into safe mode is to tap the F8 key a few times during bootup.

If we can`t get your computer cleaned up, you may be looking at a reformat and reinstall.

Hijack Log

Ok I couldn't get into safe mode but I ran hijack this in regular mode (don't know if you can use it if it's not in safe mode) but here it is...

 

[howard_hopkinso]

Your system is infected with the vundo trojan.

First go HERE and follow the instructions.

Then see if you can get into safe mode.

Then, post a fresh HJT log.

Regards Howard

 

[kristins1877]

I rand the vundo fix posted and I was able to enter safe mode and rerun hijackthis. Attached is the new log:

I followed the above instructions and attached the new hijack log. I think I am running smoothly (for now!) I really appreiciate all of the help - I have had 2 techs at my house that couldn't fix it. You guys are AWESOME!

I will update later to let you know if I am still running good

 

[howard_hopkinso]

Have HJT fix all your 015 trusted zone entries. They are nasty. Never trust anything.

Other than that, your system is clean.

Regards Howard

 

[sllewe]

Glad to hear you got things working ok.

Howard is very good a HJT logs.

 

[howard_hopkinso]

Just as a thought kristins1877.
