Mod edit: Moved from the Xp forum--PK

Machine: Gateway GM5076E; 3.2 Gh (dual) 2G RAM; ATI Radeon x1900GT(PCI);Windows XP Media Center 5.1; using DSL broadband

Protection: McAfee Security Center and Spy Sweeper used regularly (viruses never identified, only a couple low risk trackers and cookies removed). Using Mozilla and Outlook Express. McAfee came preinstalled and recently I did activate the subscription after the trial period.

Bleeping Computer Preparation Guide for use before posting: I completed every step and used Housecall, no problems identified, nothing removed except for a couple of low risk items by Ad-Aware.

Problem: This new machine running great until about a week ago. Never any real problems except the usual irritating AOL pop-ups and its trying to get me to install PortMagic on my computer (I'm not an AOL user and will probably try to uninstall it completely at the first opportunity). Fending off AOL wanting to install Port Magic may have initiated some problems. I had originally checked "never use Port Magic on this computer", but later a window popped up any way asking again. I tried to decline the install, and at about that time several things started. I remember thinking at the time that either I had mis-clicked or that AOL had installed it anyway. First I had trouble getting the taskbar to appear at start up. Booted in Safe mode and virus-scanned and ran Spy Sweeper and found nothing, except sure enough Port Magic was there in the add/remove window (I later uninstalled it). Got an odd error message and uninstalled and re-installed Spy Sweeper with no problem. I did run <sfc /scannow> once on the machine, thinking some system files may have been corrupted, but I couldn't say for sure that this solved anything. The taskbar problem appeared to resolve spontaneously (or for reasons I don't know).

At the same time I began to notice two other things that did not go away. I began to get messages of the following general nature at startup and shutdown and occasionally when running several applications:

Application error <app name>: The instruction at 0x7c80979d referenced memory at 0x00194020. The memory could not be written.

The above type application error occurs consistently at startup (almost invariably MSKDetct.exe) and at shut down (almost invariably ehSched.exe). They have also occured during use of the computer with various apps, including on one occasion when shutting down after "start->run->dxdiag"

The other issue is that I know get a "program not responding" and a shutting down window for .NET-BroadcastEventWindow 2.0.0 when shutting down the computer. I simply wait for the window to indicate the program is shut down, click close, and the computer finishes shutting down without event.

I'd have a hard time saying the performance of the computer is slower or more sluggish in general at this point. Perhaps a little bit. The router seems to work well, except for an occasional typical need to reset it. Video card working OK as near as I can tell.

That's my story, as well and honestly as I can tell it.

Here's a fresh HJT log, in case you need. I don't really understand these logs, but these 2 caught my eye:

O10 - Broken Internet access because of LSP provider 'connwsp.dll' missing

Hello whitejak and welcome to the BC HijackThis forum. I see no signs of viruses or malware in the log. It is clean.

connwsp.dll is part of PortMagic. If this program was uninstalled it might be that it did not clean up properly after itself. Check for this folder and see if it exists:C:\PROGRAM FILES\PURE NETOWRKS\PORT MAGIC
If so, check the Add/Remove Programs to make sure that it did not get installed again. If it is not there then proceed with the following.

Download LSP-Fix to your desktop. Disconnect from the Internet and close all Internet Explorer Windows. Run LspFix.exe and click in the checkbox for I know what I'm doing. Click on each listing of 'connwsp.dll and then move it into the Remove section by clicking on the >> button that points to the right. When all instances of this dll are in the Remove section press the Finish button.

Now reboot to finish this part.

Next, remove the startup entry for Port Magic by doing the following.

Start HijackThis and click the Scan button to perform a scan. Look for the following items and click in the checkbox in front of each item to select it:O4 - HKLM\..\Run: [Pure Networks Port Magic] "C:\PROGRA~1\PURENE~1\PORTMA~1\PortAOL.exe" -Run
Now close ALL open windows except HijackThis and click the Fix Checked button to finish the repair and then reboot the machine.

Let me know if you run into any problems with the above instructions. Otherwise, you are good to go.

This is a follow up/resolution note:

First of all, thank you OldTimer for helping me with this. It appears so far that the problems are resolved.

I performed the fixes precisely as you instructed and did not seem to have any problems. LSP-fix removed some connwsp.dll files, and HJT removed the entry you specified. I confirmed this with a follow-up HJT logfile, which I am electing not to paste into this response (unless you request). Three shutdown/startups later it appears that the Application errors(Memory Can't Be Read) and the "not responding--> end now message at shutdown are NO LONGER present.

I did notice, however, that in Start UP ---> "All Programs list" there was an entry for Pure Networks pointing only to a sub-entry entitled "Pure Networks website". I searched for files and found the folder and the website entry in Documents and Settings/All Users/StartMenu/Programs. These were just a folder and a very small file that I deduced was a link to the website, so I just deleted them without any repercussions. Now a search for Pure Networks appears clean as does the StartUp Program Menu.

Thank you so much for taking the time to look at this and help me.

You're very welcome whitejak. I'm glad that we could help.

Now that your malware issues have been resolved I will close this topic. If you have any new malware issues in the future then please start a new topic.


Have a safe and happy computing day!
