My Acer is stuck in Safe Mode after a system restore?

The other night, I got this pop-up asking if a certain program (don't remember which) could make a change to my computer. I always click 'No' when these things pop up, but this one just kept popping up, so I went ahead and clicked 'Yes.' Then my computer automatically restarted and instead of letting me log in to my desktop, this scan searching for errors popped up instead. It would tell me there was a problem while scanning however, and that I would just have to restart or shut down my computer. If I restarted it, it would just do the same thing every time. So then I went into the other options on the screen and went ahead and did a system restore (I do believe it's called) where you pretty much delete everything off your computer and it's the way it is when you first bought it. That seemed to be doing pretty well until it got to the 18th out of 19 steps...the System Cleanup. It would restart my computer and suggest I go into Safe Mode and delete any reccently installed programs. I haven't installed any reccently, and even if I have, I don't remember what it was or what I should delete! If I choose to reboot in Normal Mode, it lets me log in, but goes right back to the 18th step and just restarts itself again. Is there a way to fix this on my own? Hope this makes sense. PLEASE HELP!
