Posted 29 May 2004 - 12:45 AM

I found a few viruses and a ton of spyware on my kid's PC. It somehow hijacked Windows Media Player. After realizing that the Restore function had been enabled, I cleaned everything with Adaware, Spybot and SpySweeper, scanned using McAfee (which removed 2 viruses), installed a new version of WMP and got all the latest MS critical updates.

But when I reboot, the spyware comes back. Looking at Adaware, it notes registry changes from VX2BetterInternet and StopPop.

Also, Adaware et a. occasionally notes that some things can't currently be removed (like c:windows\twaintec.dll), but after it runs when the PC is rebooted, everything "seems" fine, though it obviously isn't.

Here is my log. Can someone tell me how to prevent this stuff from coming back to life after a reboot? Thanks.

Thanks, kwgagel.

BTW, I just did a VirusScan and while no files were found infected, it found the following programs:

IPSentry
Adware-SearchCentrix

Looking carefully, it looks like they exist in my Temporary Files (but possibly for a different user for this PC).

The wierd thing is that I see a folder I've never seen before. Under
c:\documents and settings, a folder that looks a little like the user name I set on this machine. Specifically, it says: firstnamelastname.firstname

Also mentions:

alchem.exe
preInsTT.exe
twaintec.dll

I'm positive I saw these things mentioned previously today when I used Adaware, Spybot, etc. I must have some type of virus/spyware that changes itself and loads up every time the machine is booted.

Thanks for taking an interest - I appreciate it.

Last thing.

The one file that won't let me delete it is:

c:\windows\twaintec.dll

Could this be the file that starts everything?

Someone else will be helping you on this. (I'm told I'm rushing in and have been asked to finish training before posting). If no one has helped you out within the next 24 hours let me know by posting here again. In the mean time I'll see if I can get someone to review what I have and get back to you.

Great.

Thanks to you and anyone else who can help.

I saw there's an article here about alchem.exe, but I couldn't read it (the hosted site is out of bandwidth).

I am filling in...

You are running HJT from your Desktop and this means that you will end up with backups all over it. You may want to put it in a folder you create like C:\HJT before you run it. Then....

Please run HJT and mark/fix:

R3 - Default URLSearchHook is missing
O2 - BHO: (no name) - {000020DD-C72E-4113-AF77-DD56626C6C42} - C:\WINDOWS\twaintec.dll
O4 - HKLM\..\Run: [dmzcqfyf] C:\WINDOWS\System32\bsqhja.exe
O4 - HKLM\..\Run: [alchem] C:\WINDOWS\alchem.exe

Then reboot into Safe Mode and find/delete. Hopefully the DLL will be gone already, but make sure Windows is set to show all hidden files to be sure. The first one may have morphed into a different random name. If you can't find it, please look for another randomly named EXE in the same folder and delete it, but don't empty your Recycle Bin:

C:\WINDOWS\System32\bsqhja.exe
C:\WINDOWS\twaintec.dll
C:\WINDOWS\alchem.exe

Then reboot and post a fresh log...

Budfred,

Well, just before I ran HT, I ran Adaware, and I didn't see any of the viruses/spyware that I usually see after a reboot.

But I ran HT as you instructed. Got rid of the searchhook thing, but my "new" log didn't have anything about twaintec, bsqhja or alchem.

I booted then in Safe Mode. Found alchem in the windows folder and deleted it (along with an alchem pf file in the prefetch folder).

Didn't find anything for bsqhja, but I did find several alchem files in my spysweeper quarantine folder - i assume that's ok to leave alone.

Anything else I'm missing? Here's my new log

Thanks again.

Looks like you got it all... You can clean that quarantine files out too, I think the program gives you that option and I don't think you want to use those files again... :lol:

Here is my prevention speech to help avoid getting infected again:

This is a good time to set up protection against further attacks. Read the article linked below about "How did I get infected". You need an antivirus that is updated, a good firewall and a spyware blocker like SpywareBlaster and also IE-Spyads. All of these have good free versions available... be very cautious about any security software that advertises in popups or other intrusive ways, they are not only usually useless, but also often have malware in them....
