I have a compaq presario 1700 notebook. I got the sasser worm. I decided to format and reinstall. ( It was overdue anyway) I tried to reinstall windows...no go...the setup program said it could not copy some "dll" files and windows setup cannot continue. So then I tried My win 2000 disk thinking it might be the Xp disk that was bad...same problem. Then I used a dos bootable disk and I formatted my hard drive using fdisk... then I cleared my master boot record using fdisk...then I unplugged the battery and power cord (for 15 minutes) in case the virus was in ram. Then I tried to reinstall my os and I have the same problem. I thought I took all the right steps to clear the pc of the virus but I guess I was wrong. Any Ideas on how I can get the os to load and/or get rid of the virus would be truly appreciated.
