CTLG.DLL Trojan

[wotsirb]

Hi,

I've recently been infected by a few trojans.
My anti virus program (PC-cillin) found them and delt with all but one of them.

Every time I open IE, PC-Cillin tells me the following:

Infectected File : C:\WINDOWS\SYSTEM32\CTLG.DLL

Virus name: TROJ_AGENT.AC

Action when virus found: Unable to clean/quarantine infected file

I have updated the anti virus software but it still comes up with the same message?
I don't have a lot of experience with stuff like this. Any suggestions or help would be greatly appriciated.

Thanks.

It would also be a good idea to do the full security sweep... if you have trojans, you probably have other malware...

This would include downloading and updating and running Spybot and AdAware... Fix the items noted in RED in Spybot and fix whatever AdAware finds... Then download HijackThis and run a log to post here... Get the new version here:

To run HJT, extract it to a permanent folder such as one you create like C:\HJT. Close all open windows and browsers and make sure that all programs are enabled if you use msconfig. Run it and Scan, then Save the log. When the log window appears, Right click to Copy it, open your browser and come here to Paste the log. Do not make any changes until it is checked since most items are either benign or essential to the computer.
