For the infected computer.... Go to www.bleepingcomputer.com and post your problem. They will post back, giving you programs to download to diagnose and repair your computer. You will need to be ON the bad computer to do this. Follow their instructions for each step. Make SURE you stay in contact every day with bleeping so they don't close your topic as abandoned. Good: It is free. Good: They try their best to not mess up your computer. Good: They are computer smart. Good: You've got nothing to lose. IF you have certain routers (Netgear is one) they are prone to hackers (Google "router types prone to hacking). Hackers can change router IPs (the numbers) on 3 types of routers. You'll need to call your Internet Provider and get your 2 legitimate IP numbers. Then, reset the router to factory settings---important---do not skip this part. Then, enter the legit IP numbers. Next use a 64 bit encrypted password on the router. I haven't had an attack since. But you must, must, must put it to factory settings first, then protect it with a strong encrypted pw. They can't get back in. Judy
