1.I found those files on my computer local disk (c:) hidden. It's strange I had this on my old hard drive and I may have pick this up surfing but what I want to know is how did it get on my brand new hard drive and at the time did not go on the internet yet it was on there how? The files: System Volume Information (folder) hiberfil.sys ntldr pagefile.sys autoexec.bat boot.ini IO.sys NTDETECT.com CONFIG.SYS Recycler (folder) I can't delete or view these files why?? I pull up windows Task Manager under processes found unkillable things running 2.I install windows xp though dos and it was acting strange during the format and creating directory screen, then it load files that I never seen before. Also during the 39mins count down blue color screen went black several times with mini dos screen and lasted 1 sec. each time. In the past this NEVER happen before.Could some malware have hidden in the memory/ddr or motherboard. 3.I have Western Digital hard drive w/ software that can format the drive but something cause it to format 90% then end in error which result in a incorrect format. Again I believe it unknown malware and yes the hard drive is new and updated. They maybe out of order but the questions kinda link together can someone help me fix, replace trash something.
