Hello,
Recently, my computer has been acting sluggishly ever since a certain series of events.
After attempting to resolve the problem by myself and being unable to, I've decided to come to this forum for help.
On the 24th of december, while accessing the internet, I receieved an error message. I'm not too sure about the exact contents of the message, but it was something about a C++ error. (I suspect it has something to do with a popup ad)
After that window popped up, my computer suddenly began to lag. Instinctively checking task manager (I do so periodically ever since my computer was infected with a backdoor in 2003) , I noticed a few abnormal processes running. They were named something like "1.exe" and "8.exe" and "relpop.exe"
After ending those processes, I checked my registry and deleted some unfamiliar keys in the HKLM\software\microsoft\windows\currentversion\run
However, my system was still not performing properly. Scanning with the Symantec online virus detection, I have found multiple viruses. (My own antivirus on my computer did not pick up anything)

(a sidenote: i have these files as i used to play around with an apache server and php last year. however, i have not touched the files in quite a few months already)
Checking through the HTML and PHP files, I noticed that an IFRAME tag had been added to the bottom of the code.
I searched for and deleted the other infected files (my system restore was off).
I then ran AdAware and scanned and cleaned up my system.
However, the problem was not over.
Ever since then, when I use the computer, the process "IEXPLORE.exe" will popup in the taskmanager every few seconds (by that i mean a new process each time).
Normally, that is just the process I see when using internet explorer. However, in task manager, the user name is called "SYSTEM" and there is NO VISIBLE window. Additionally, the process takes up around 18K in MEM usage EACH, and it opens until there are around 8 IEXPLORE.exe processes.
Not only that, every 10 minutes or so, a message box will pop up and announce:
16 Bit MS_DOS subsystem
C:\DOCUME~1\HCH2\LOCALS~1\Temp\WinNNN.exe
The NTVDM CPU has encountered an illegal instruction.
CS:053c IP:b54d OP:ff ff ff ff ff Choose 'Close' to terminate the application.
where the NNN in the file name is random characters.
Its fustrating because I cannot seem to find the process which spawns both the message boxes and the hidden IEXPLORE.exe processes.
Can anyone help me solve this problem and restore order in my computer?
Here are my system specifications:
Intel Pentium 3 800MHZ processor
326 MB RAM (Its actually a 256MB card and a 64MB card)
Microsoft Windows XP (service pack 1)
Microsoft IE6

It will be really good if someone could offer me assistance. Thank you.
(and maybe i shouldnt have tried tackling the problem myself at first)
EDIT: After browsing the forums a little, I have some additional info to put here.]
Here is a screenshot of the multiple IEXPLORE.exe processes, and I attempted to resolve the host using TCPView but it's weird.

Also, here are results for a scan that i did with Activescan.

C:\Documents and Settings\HCH2\Local Settings\Temp\ywky.dll is infected with Trojan Horse
C:\Documents and Settings\HCH2\Local Settings\Temp\Ztgx.dll is infected with Infostealer.Gampass
(a sidenote: i have these files as i used to play around with an apache server and php last year. however, i have not touched the files in quite a few months already)
Checking through the HTML and PHP files, I noticed that an IFRAME tag had been added to the bottom of the code.
I searched for and deleted the other infected files (my system restore was off).
I then ran AdAware and scanned and cleaned up my system.
However, the problem was not over.
Ever since then, when I use the computer, the process "IEXPLORE.exe" will popup in the taskmanager every few seconds (by that i mean a new process each time).
Normally, that is just the process I see when using internet explorer. However, in task manager, the user name is called "SYSTEM" and there is NO VISIBLE window. Additionally, the process takes up around 18K in MEM usage EACH, and it opens until there are around 8 IEXPLORE.exe processes.
Not only that, every 10 minutes or so, a message box will pop up and announce:
16 Bit MS_DOS subsystem
C:\DOCUME~1\HCH2\LOCALS~1\Temp\WinNNN.exe
The NTVDM CPU has encountered an illegal instruction.
CS:053c IP:b54d OP:ff ff ff ff ff Choose 'Close' to terminate the application.
where the NNN in the file name is random characters.
Its fustrating because I cannot seem to find the process which spawns both the message boxes and the hidden IEXPLORE.exe processes.
Can anyone help me solve this problem and restore order in my computer?
Here are my system specifications:
Intel Pentium 3 800MHZ processor
326 MB RAM (Its actually a 256MB card and a 64MB card)
Microsoft Windows XP (service pack 1)
Microsoft IE6

It will be really good if someone could offer me assistance. Thank you.
(and maybe i shouldnt have tried tackling the problem myself at first)
EDIT: After browsing the forums a little, I have some additional info to put here.]
Here is a screenshot of the multiple IEXPLORE.exe processes, and I attempted to resolve the host using TCPView but it's weird.

Also, here are results for a scan that i did with Activescan.
