I would recommend you follow the advice given by Blues_Harp28, Adwcleaner should remove any Adware that is causing the problem with your browser. If the Adware persists it will need further action to remove it which either I or Blues_Harp28 can guide you through.
FYI: CCLeaner is a great tool for general cleaning up, but you should not use the registry cleaner unless you have sufficient knowledge to determine if the registry keys it finds should or should not be removed. The registry should not be tampered with and removing orphaned registry keys will make no noticeable difference to your PC's performance and that is all the registry cleaner will do. Unfortunately all registry cleaner/optimizer programs can make mistakes and remove keys that Windows or your software require to function correctly. The risk of using any type of registry cleaner far outweighs the benefits.
I see in your systems details that you only have 1GB of memory fitted. Your motherboard can take a maximum of 4GB. It will be of some benefit to your systems performance if you fit more memory, maxing it out to the full 4GB would speed things up a little.
