If you suspect it is caused by virus or spyware then you need to run some
tougher protection software to find and remove the culprit. Otherwise,
replace your components one by one until the problem disappears. Do the
monitor first, because that's probably simpler, then do the video adapter
card.

The last few days I have been getting a herringbone type pattern on
highlighted icons and around the edge of open windows. Then when I shut
down
windows the whole screen is covered with it during shutdown. Using
WIN98SE
on this machine for a long time, this is a recent change. Have upto date
antivirus and have run some antispyware software and don't find anything.
But
still suspect it has something to do with adware or spyware. Anyone else
seen
this and know of cause and solution?

Thanks
