Ok. This is my first time posting on BC so bear with me if I don't give the correct/necessary information.

For awhile, I've been getting some odd symptoms. After my computer is on for a certain period of time, usually several hours or so, system files just disappear, and I can't get anything done unless I restart. When I restart, a disk check is always performed. I'm not sure, but I think this started some time after I ran ComboFix to get rid of a nasty rootkit, which it did.

The first I noticed is when my internet gets rather glitchy and slow. I went to "repair" the connection, and I got this right away: "Failed to query tcp/ip settings of the connection."

I thought that was it, so I did some research from my iPod Touch on the file and when I went into the system to check and make sure the file wasn't a virus imposter, I couldn't find any of the system files. If I tried to run chkdsk.exe with a run command, it told me it couldn't find "chkdsk.exe." If I try to open task manager, I get an error that was something like this: "0xc000000142 application failed to initialize." If I recall correctly, I could not find any *.sys files at all, even when viewing hidden and system files.

All this happens if I am using the computer at the time of the problem. If not, I come back to the computer, usually with a "Bad Pool Caller" BSOD.

I have run a few different antiviruses but nothing comes up.

Something that baffled me to the point of coming to BC, was that I have repaired the OS with the disk (not completely wiped, just repaired) multiple times... I even uninstalled and reinstalled most drivers.

I've been bearing with it for awhile now, but I finally got sick of it when it failed while I was working on a project. I hadn't saved in several hours, and lost it all. I'm sick of it now.

Can anyone get me pointed in the right direction?

Here is some system information:

OS Name: Microsoft Windows XP Professional
Version: 5.1.2600 Service Pack 3 Build 2600
OS Manufacturer: Microsoft Corporation
System Manufacturer: LENOVO
System Model: 2743DGU

Once again, I'm new to this, so let me know if any info is needed/not needed.

Hi Steel Anjel,

Since you have already run Combofix, please follow the instructions in ==>Malware Removal and Log Section Preparation Guide<==.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include the link to this topic in your new topic and a description of your computer issues and what you have done to resolve them.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep.
