ok here is the deal. my neighbor got one of these for free w/fios. gave it to her 10yr old kid. she gives it to me saying it don't work. when it went to boot up it would give the significant hardware change boot speil. tried to boot in every mode imagineable. finally used the included roxio system restore and got it to boot, somewhat. once i got past the explorer.exe issue.(endtask then start task) i could see the taskbar and desktop icons. norton was expired, loaded avg pro via sd card and ran virus scan. after almost two hours comes back with 1777 viruses. i've tried everything to purge the drive of the virus(es) and nothing has worked. is the only option a full format and fresh install?
