Can I get computer help please

every week i run Ccleaner (to clean useless files), Lavasoft Ad-aware (spyware, trojans, keyloggers) and Auslogics Disk Defrag (rearrange the space, optimizes system, makes it faster). They are all free and work well. And i don't think you can delete IE.
 
To "remove" IE under Win 7/Vista:

Go to 'Control Panel' --> 'Programs and Features' --> 'Turn Windows features on or off' and simply uncheck IE

Under XP:

Go to 'Control Panel' --> 'Add or Remove Programs' --> 'Add/Remove Windows Components' and uncheck IE
