Hello.

A couple days ago I noticed my computer acting strange, in that internet browsing was odd as my web browser would randomly stop responding acting liek it was offline, however some things like MSN or IRC would still work.
Other times MSN or IRC would not work, it was just seemingly random.

I did some spyware and virus scans and came up with a file called "msnetex.dll" which was removed.
However, after that was done my internet was completely dead. I could log on to the internet, but everything acted like it was offline.

I did some digging around and found out about a program call LSPfix, so I installed and ran it.
This put the "msnetex.dll" file back and caused the orignal problems.
After a bought of virus scanning and spyware removing I could get rid of this file and run the internet.

The problem is now I am stuck with the internet running slow on websites and randomly cutting out certain programs and also much higher internet activity than usual, no matter how many antivirus or spyware checks I do on my system nothing can be detected.

Something has to be there though as today I installed a Firewall (Zonealarm) and that is detected Explorer.exe spamming out emails.

I cannot find anything wrong with my system but something is clearly wrong, and apart from formatting my main HDD with windows (and hoping the virus doesn't stay on my backup drives, considering I cant detect it) I have no idea what to do.
I may try just reinstalling windows and seeing if that helps first.

Any advice possible would be greatly appreciated.

See this link for information about Explorer.exe. It is not to be confused with the legitimate Microsoft file C:\Windows\explorer.exe.

You need to find out where this Explorer.exe lives on your hard drive. Does it show up in Task Manager?

According to Zonealarm the explorer.exe is in:
C:\WINDOWS
Which I presume would make it C:\windows\explorer.exe

This is definitely the one sending out emails.

I shall upload my HijackThis log asap.

Well, I went ahead and reinstalled windows, and for now that seems to have worked.
Explorer.exe isn't trying to send emails as far as I can tell (Zonealarm isn't giving me any alarters nor is my internet activity abnormal.)
So I think I'm in the clear unless my internet starts buggering up like it was doing.

Quite frankly I'm too tired of fiddling around with my PC, will do some virus scans and some spywqare scans to make sure, but I'm going to leave it running and see if anything strange happens.

However, any advice or tips that someone could offer that was relevant to my problems I would still appreciate.

In order to give some sound advice can you tell us what you have on antivirus- and antispyware software?

Sure.

For anti-virus programs I have used Nod32 and AVG antivirus.
For spyware removal programs I've used Spybot and Ad-aware.

Everything has been updated to the latest versions and all latest definitions, etc.

Hi RoboJoe,

I closed your HJT topic since you have reloaded Windows. You may continue to follow this thread with its suggestions. If you continue to have problems, please post another log.

One note please... If you do post another HJT log, please follow ONLY the advice of the HJT team member that assists you. Doing otherwise can cause problems and delay the cleaning of your computer.

Take care RoboJoe.

RoboJoe, you should not have 2 anti-virus programs running on your computer at the same time. If you do they tend to fight against each other and actually leave you less protected than if you only have one.
