Windows 7: startup repair

I'm having problems starting up after a virus problem. I booted up into Startup Repair with repair DVD, and it's been "Attempting Repairs" for quite some time. I am using windows 7.

do this: What is Windows Defender Offline? you will obviously need to do it with another computer.

I downloaded windows defender onto a usb. do i need the recovery dvd in too?

You should be able to just boot with the stick..

well the defender wont boot from dvd or usb. thank for ur help

I put DVD in drive and it says "start up repair" ur computer was unable to start...start up repair is checking system for problems" my guess is that its not booting from dvd drive so I pressed F2 to change order and boot from cd/dvd drive. still not booting from dvd.

it SHOULD boot.. check these Windows Defender Offline: frequently asked questions

k thx. tried that. now it says Remove disks or other media. press any key to restart
when i remove usb and dvd, starts the start up repair again. uhhhhgggg!

maybe i didnt download the defender correctly. the file ext is "exe"

it's an exe, then you double clicked it and followed instructions on how to load it on to usb stick or burn it right?
