hi there you should try this this will work hopefully go to this web page. www.superantispyware.com
or if that web page dose not work go to www.malwarebytes.com chose 1 of those. if you cant get rid of the infection in normal mode try going into safe mode and scanning. and chuter i would like you to know avg dose not have rootkit protection.. so im sure its a rootkit on your computer. that would explain the redirections.
please try on of those 2 anti spyware products. www.malwarebytes.com www.superantispyware.com
paste one of those in your web browser. i hope this helps you. and download the free version not paid.
