Monitor Driver

I had to re-install 98se due to my system being hijacked
by an ad-ware virus & now my monitor won't work right.
Windows identified the device correctly the first time,
but only showed one driver to use for it & now that I've
tried to change it, it won't identify the monitor. I'm so
confused! Trying to view websites & even my email is very
difficult now.
When I try to select a driver under the monitor tab on
advanced settings, it shows me one list of "drivers" and
when I try to select a driver under the adapter tab on
advanced settings, it shows me a different list. I am
totally lost! Can anyone help?
