What is wrong with my computer???

I am having a lot of trouble with my computer. A few weeks ago I started getting a pop-up error message that says: ""msmsgs.exe Application Error: The instruction at 0x00f89bb3 referenced memory at 0x10005260. The memory could not be read." This pops up all the time, whether I'm on the internet or working in a Word document--all the time.

When I e-mailed Dell tech support they said it was spyware. So I ran my virus scan to make sure that wasn't the problem. No viruses. I then came here and followed the directions to remove viruses & spyware. I downloaded and ran Ad-Aware SE, Ad-Aware VX2 Cleaner Plug-in, CCleaner, Spybot, Spyware Blaster, McAfee AVERT Stinger, CWShredder, Kill2me. I did everything as explained, step-by-step. Several viruses/adwar/malware were found and deleted/quarantined. When I rebooted in normal mode, the popup message started back immediately.

I have also removed MSN messenger from the add/remove window components window.

I wasn't sure if I needed to install and run Hijack This, so I thought I'd post and see if there's anyone who's had this problem or knows how to fix it. From reading this, you can tell that I'm no computer expert. I'm at a loss on what to do now. I'm leaning towards taking it to someone who can repair it, but I'd really like to figure it out on my own - very stubborn. Does anyone have any thoughts on what's going on and how I can fix it? Thanks so much for your help!

I've attached the log file. Let me know what you think.

Thanks!

I just realized that I ran hijack this from the wrong place - temp file. I re-ran it, so here's the corrected log. Please ignore last post. Thanks!

 

Thanks for the reply Chaslang. I did everything that I could exactly as you said. The BookmarkExpress wasn't in my Add/Remove Programs list, so I couldn't uninstall it from there. After running HijackThis, I was able to fix everything except the "04-HKCU\...Run:[Weather]C:\Program Files...." -the 3rd one down. It wasn't there - I guess because I was able to remove the WeatherBug in the Add/Remove Programs window. When I was in safe mode, I wasn't able to delete C:\WINDOWS\System32\BMUpdate.exe because it wasn't there, but I did delete the other one. Other than those things, I was able to do everything else exactly as you said.

So far there have been no popups, but sometimes it doesn't start popping up right away. I've attached my current HijackThis logfile for you to look at. Hopefully the problem has been fixed and if so, THANK YOU SO MUCH!! If it comes back, I'll post again and let you know.

Thanks again!
