Avoid Internet Explorer like the plague. IE will only cause you more problems.
AVG anti-virus is mediocre at best. Go with Avast or Avira anti-virus or even the free version of Panda.
Along with that get a decent anti-spyware like Ad-Aware or Malwarebytes Antimalware. I am sure Avast combines well with the 2 antispyware programs above, but not sure about Avira or Panda.
