well im guessing that its a virus just wanting to cause you to get upset. deal is virus protection wont always...sometimes flat out wont work if you already have a virus creepin behind the scences!
i had this isssue once and all i had to do was use my RECOVERY DISC to set it to factory setting. Mine was 2 dvd discs and i had a dvd burner of course. but thats only when i bought it. it says you should make one and i did and i simply start it like the day i bought it! your harddrive will be erased but ensures that the virus wont be in the hard drive anymore. my computer has 2 70gb hard drives and i simply moved my favorite files to the other hardrive which doesnt have my OS on it!
So if you dont have a recovery disc then your best option is this! your number on you pc either near the back, side or front on a sticker has a code that is yours to keep for life.. if its Windows Xp home or xp pro or xp OFFICE then that OS is yours and now you need to either find a windows installer disc that has your OS.
So if you happen to have a windows disc with ur OS you can use that to reinstall ur OS with its NUMBER and it will WIPE UR HARDDRIVE CLEAN BUT FIXS ALMOST ANY PROBLEM> LIKE THE DAY YOU BOUGHT IT. some just start up while windows runs . some computers you need to put the disc in ur cd or dvd rom and then start restart ur computer and hit the commands at the begining! its either F2, F10 or any F set it says! either chose boot from ur DVD or CD rom and hit ok or enter. or for some users go to BIOS SETUP ]F2[ for most all comps then find where boot squence is and set ur DVD or CD rom as the first to boot from! but make sure when ur done installing ur os change it to ur hardrive. o make sure that you know you can transfer your key files you want to keep to a external device!
So if you dont have a CD or DVD windows installer if you have a CD or DVD burner you can downlaod a WINDOWS XP HOME ISO bootable image and use a A PROGRAM THAT LETS YOU BURN BOOTABLE ISOs TO A CD[ IPREFER CD DUE TO XP HOME OR XP PRO OR XP OFFICE IS ONLY AROUND 600MBS dvds may not work.. torrents can help you find ISOs here is home if that what u have
. BITTORRENT as spelled google it and then download install it then go to
thepiratebay.org and search for your OS then download it and chose bittorrent as the program to open and it will download and it will be in MY documents then downloads. use the cd burning program to mount the file the use it as a windows installer disc! sorry if this doesnt help! i hope this works out! remember ur download your OS and that ur hardraive will be erased to ensure a clean hardrive
