I have a small network in home /office. Server with windows 2003 SBS and 4 pc attached. Unfortunately my children have managed to get some viruses on some of the machines. The one currently being used has a relatively minor hijacking virus that despite using Norton, Adaware, and TDS3 shows up on none. The result is to take over the browser. I have attached a copy of the log and should someone have time or inclination I would appreciate it. The second machine has been completely over-run. Knowing I had an infection I decided to buy Norton. Installation made a pre-system check and, finding no obvious problem, proceeded tp install. First re-boot and a series of files were being found by Norton but it seems they were being re-generated as fast as they could be deleted or whatever. Having tried a safe re-boot and re running Norton the problem simply got worse. I did try removing what were the evident causes fron the start up but they were simply re-generated. Since opening task manager is to watch the list of programs grow by the second I suspect the only answer is to completely wipe the disk. My question therefore is, assuming that a complete wipe is the only answer. how to format hte disk? Cam I dig out some old DOS disks and see if it will allow me to re-format or is there a neat way round the barrier which XP seems to put in the way?
