How can I completely delete the Trojan IRC from my network?

I have a sever IBM and 30 clients I have been finding since 2 weeks ago in my server the virus Trojan IRC and what I have been doing is erasing manually the archives in Win NT system32 but I have noticed that they alls regenerate automatically...

I am in the process of implementing a new server but I do not want to include it in my network untill I am sure that the virus has been completly eleminated...What I am going to do with my server is re-install the operating system all over again however what I am un sure of is what I am going to do with my clients...

I called symantec and they advised that I do not have to re install the OS in all my clients and that what I need to do is run the antivirus scan in safe mode to detect the trojan.....

I have already downloaded a trojanhunter tool to use from Mischel Internet Security and I am thinking of running it on all my clients and also one called AD-Aware SE because I found information concerning an application that I downloaded free from the internet called date manager and trhough that program I got adware.trojan

Could you help me giving me advices and tips about that what we can do with my clients?

Thanks in advance!

Hi modeza,

With only 30 clients, I suggest you just disconnect them all from the network (you might have to do this in the weekend) and clean them up one-by one so they can't infect each other while cleaning.
Then, reconnect them all to the network after you've verified they're clean. See if that works for you.
adware.trojan is pretty easy to fix with Ad-aware SE normally, just make sure you use the latest reference file.

Thanks a lot but I am still concern about if do I have to reinstall the operating system again to each client or just use the tools that I already downloaded to clean the virus?
