i dont know if this the right place to post it but i been having with a worm that infects my PCs... i have the latest norton antivirus and up to date virus definition but the problem is that it keeps coming back and norton av couldnt do anything... i reformatted all my pcs(4) and all other partitions so its like a new harddisk but still it comes back... what can u suggest the best antivirus software that can prevent or stop worms from infecting a file or spreading through out the network... thx
