Okay, you have malware or an advertising program installed.
First thing to do is to clear your cache, that's rarely, but possibly the fix to the solution.
If that doesn't work, go to 'Uninstall of change a program' and look for anything suspicious (look for a program with 'ad' in its name), if you do, uninstall it immediately.
If it's not a program, then install Malware Bytes and run a 'quick scan', this is probably the best anti-malware software to use.
Thats an issue with your computer. We don't have such ads. Clean your computer as its possible its an add virus or something of the sort. Also, get a safer browser than IE or/and some add blockers.
