I have 4 windows xp in my network, all of them are infected with an unknown virus.
I have tried avg, malwarebyte, microsoft security and it didn't work also I created a karpesky's bootable cd and "No virus found" also tried conflicker tools but it just said "no virus found". the problems is I can not access to any computer or share folder start -> run -> \\computer1 start asking for password when I type the password just said it didn't find the domain. phisical conectivity is fine. all the computer has a services with an strange name like in the picture.
basically I would like to know how to remove it without format my pc?
