When I'm on the internet a message pops up Runtime Error C++, and I have turn off, or restart computer. I need to get rid of this .

Since you did not give much detail on your situation lets hit some basic points:

Have you done a spyware and virus scan lately?

If you do not have security software installed may I suggest using AVG Free Edition AVG Free - Download installation files & documentation (http://free.avg.com/download?prd=afe) for anti-virus and Ad-Aware 2008 Ad-Aware 2008 - Reviews and free Ad-Aware 2008 downloads at Download.com (http://www.download.com/Ad-Aware-2008/3000-8022_4-10045910.html?part=dl-ad-aware&subj=dl&tag=top5&cdlPid=10903602) for anti-spyware. After downloading and installing please run a full system scan with both programs

Is your operating system full patched?

Click Start > All Programs > Windows Update
Follow Microsoft's instruction to download and install the latest Windows updates

If all else fails use a more secure and stable browser like Firefox Firefox web browser | Faster, more secure, & customizable (http://www.mozilla.com/en-US/firefox/) which are much less prone to problems compared to IE.
