Had virus alert to delete file sulfnbk.exe from my c drive, which I did much to my delight being a new user. Soon after I was alerted to the fact that this was a hoax. I contacted secuityresponse.systantec.com and found some really good info about virus's and hoax virus's including how to restore the deleted file. Try as I may I cannot restore the file from my back up disks. I keep getting warnings that my system is going to fail and I am tearing my hair out. Please what to do?
