I have wiped this computer clean at least 11 times in less than a year, My "Airplane Mode" just turned itself on at times. I could not make a complete set of Recovery Disc, something changed the format on all my videos, some have just audio no visua. Updates always had an error, or said run as Admin but would not allow. I ran "Hijack This" tonight after reading about it on this site. I'm pretty lost trying to figure out the report but did see that there was a hijacker, trojans & I don't know what else. I followed the instructions and it said "could not Analyze" no internet connection, I was online at the time. It gave me manual instructions to go to Start type NotepadC;\windows\system32\drivers\etc\hosts. It says not found. I am in the fight of my life trying to charge the nursing home that killed my mother and change state laws, most all of my research and correspondents are through this computer. I thought I was somewhat knowledable with computers but i'm just at the end of my rope. Any help will be appreciated. Thank you.
