Remove Sweetpacks Virus – Instruction to Remove Sweetpacks

‘A few days ago I noticed small pop-up ads & full-screen ads appearing while using Internet Explorer.  Some of the time I'm able to "x" out of the page but other times I have to close down Internet Explorer & start over.  I've seen the name "sweetpacks.com" appear on the tab name.  I think this may be a virus.  Currently, I'm running Microsoft Security Essentials as my anti-virus software with live updates.  I checked that page & it does not show any viruses as being detected.  How can I get rid of "sweet packs"?’

‘I recently found out that I have a virus on my laptop called sweet packs but after removing most of it it my laptop still has the sweet packs internet explorer toolbar. When I try to uninstall this program it asks my permission to allow windows/installer/3fa1a7 the origin location of this is a sweet packs folder but it needs to allow it to uninstall please help’
