Have windows XP. This once happened to me from downloading UTube documentaries. I just restored from a prior date. Then ran a Anti Program and all kinds of garbage showed up.
Now it has happened again and it has wiped out my restore points. Nothing showed up when I ran another Anti Program. When I Try to install A new Anti Program it reboots the Computer even in Safe Mode. Unfortunately I don't have the XP disc to restore ( is there anywhere to downloaded 1). Tried to find the restore points navigating with another XP laptop in the hard-dive Program files. Couldn't find them. This Computer is a PC not hooked up to the internet.
At this point I'm thinking of zeroing out the hard-dive and going to 2000. What a loss.
Does anyone have a solution?
