Trojan infected a system file of my XP.

Can you help me manually remove this trojan? Or offer another solution?
The computer is an old Cybernet Model ZPC-9000.
AVG alerted me to a trojan horse "Collected_c.BCMP" ..."cannot be cleaned."
Object name: c:\WINDOWS\system32\drivers\tcpip.sys
Apparently this causes the firewall to be off and "settings cannot be displayed."
Attempts to go online return "That page is not available" on Chrome and "Cannot locate server" on Firefox
p.s I looked for a similar thread. Didn't see one.

above is from avg labs. You should read this, but they refer you to microsoft kb articles.

there are a couple of options for you

1. reinstall OS after backing up data , OR,

2. do the following:

Download, install, update and do full scan with these free malware detection programs:

Malwarebytes (MBAM):
SUPERAntiSpyware: (SAS):

Remove all found, reboot, and run again until scans run clean, these can be removed afterwards if you so choose. Run scans one at a time, please.

After scans run clean then I would

1. read this checklist carefully and then download Microsoft security essentials and save to your desktop, then uninstall Avg using their removal tool

2. then install MSE and let it update.

3. AVG is not considered a very good product.

MSE Download
MSE installation checklist

installing an antivirus on an infected pc will not clean it, you have to have a clean pc first, so definetly run the above scans first.


surprisingly this trojan is only listed in avg websites, can not find any other info on it except at their website.
