I am managing a small eterogeneal network:
28 PC of 6 different kind and 2 different OS (windows 2000 and windows 98)
connected to the internet through a CISCO 800 with NAT and ADSL connection.
I used to have a Windows 2000 Server to mange the access but I had too many problems due to hardware incompatibility (expecially video cards) and at a certain point it crashed and I had to format it.
Now it is reinstalled and I am rebuilding the users list but it will take a while.
Now I am working with a paritetical network.
Unfortunately my users are student that have a very peculiar attraction to dangerous sites and they always get all kind of vermins in the PCs and I am pretty tired of constantly try to fix the problems they cause
So I wander if there is somebody who can help me in setting up a minimal security on this network because I really don't know much about it.
I also would like to know if I can post all the logs of Hijackthis and somebody can help me out in ceasing the services that are not necessary and programs and services that are to be consider malware, spyware etc.
Beside the danger, and the annoying situation of the never ending formatting activity, my problem is that we are a school and have not much money, and some of the computers are old and slow, but we cannot change them so I need to try to optimise them.
The list of software that we run:
Office 2000 professional
Some electric circuits simulators
on some computers we need to install messengers: Yahoo, ICQ, MSN, miRC.
As Antivirus we run AVG (grisoft.com)
I would like to use ZoneAlarm as firewall (but I accept suggestions for better ones)
For spyware we use Spysweeper but lately it6 shown to be inadequate
Now the school is over, so I have around a month to tune everything so I formatted all PCs, downloaded all the upgrades, then I run Hijackthis and looked at the log No CLUE!
Can anybody help?
I attach one of the logs for now.
Thank you all
