I was somehow forced to download this file, prob my stupidity and it keeps giving me security warnings what can i do

Try this...

Go to your IE Internet options and clear the cache.
If you need details on how to do this provide IE Version info.

If you know the file name, delete the downloaded file.
If installed, goto the Control Panel and uninstall the program.
If details are needed, provide Operating System information, ie XP, Vista, etc.

After all this...reboot.

Good Luck...
