Thanks for the advice guys, on some of the computers we have downloaded McAfee Site Adviser and told the teachers only to go to the "green" sites. So far we can't find a common ground other than Google searches that might attribute to them getting infected.

Hey guys just wondering if anyone has any insight of where most of this Malware comes from? I have heard of possible exploits in Adobe Reader and Adobe Flash and Java, but have recently cleaned up a machine that got reinfected after all of the above programs were updated. I work in the school system and most of our machines are Windows XP Pro and Windows Vista Business. I would say that about 90% of the machines that get infected are running XP Pro SP3. The schools just purchased Sophos AV and so far that seems to be working, as we haven't seen a machine get infected that was running this AV software. Two of the last infections the teachers said they Googled free lesson plans. I opened the page on my Mac but didn't see anything out of the ordinary.
