WinXP Professional version 2002 SP 3, automatic updates on, last update yesterday.
Virus scanner: McAfee 8.5, virus definitiosn up to date.
Firewall: FortiClient, setting "Normal".

Last sunday I was infected with a host of virii; it seemed that McAfee was able to block them all. I wasn't convinced though, found through FortiClient that a program ccdrive32 opened connections on almost every port. Since then, all hell broke loose.

On advice of a friend, I downloaded, installed and ran: MABM, SuperAntiSpyware, ComboFix (yes, I later read you shouldn't do that unsupervised) and VundoFix. VundoFix found no problems, SAS found and deleted around 30 trojans, ComboFix found a rootkit but couldn't delete it. SAS, MABM or McAfee find no rootkits, btw. Neither McAfee or the FortiClient scanner found anything at all.

After 3 days of intensive scanning and repairs, SAS, MABM and McAfee find no problems on a scan. However, every 5 minutes a warning from McAfee pops up:

I googled, and found similar problems (http://community.norton.com/t5/Norton-Internet-Security-Norton/Auto-protect-blocked-security-risk-W32-IRCBot-Gen-How-do-I-stop/m-p/175636) but no resolutions.

Clearly, I have some infection that my current programs can't fix. Any ideas? Thanks in advance!

Edit: I found this in my scan log:
2/3/2010 12:57:26 PM Niet gescand (time-out voor scan) NT AUTHORITY\SYSTEM C:\Program Files\Java\jre6\bin\jqs.exe C:\Program Files\Java\jre6\lib\rt.jar
2/3/2010 1:00:52 PM Verwijderd NT AUTHORITY\NETWORK SERVICE C:\WINDOWS\system32\svchost.exe C:\DOCUMENTS AND SETTINGS\NETWORKSERVICE\LOCAL SETTINGS\TEMP\NYLP.TMP\SVCHOST.EXE W32/IRCbot.gen.ah (Virus)

The second line is the first time the message seems to have popped up; the line before was started 3 minutes before and for some reason mentions: "not scanned".

Hello as a Rootkit is present you will need to post an HJT/DDS log to get it safely removed.
Include your combofix log.

You will need to run HJT/DDS.
Please follow this guide. go and do steps 6 thru 8 ,, Preparation Guide For Use Before Using Hijackthis. Then go here HijackThis Logs and Virus/Trojan/Spyware/Malware Removal ,click New Topic,give it a relevant Title and post that complete log.

Let me know if it went OK.

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
