This link Required Reading - Home User Assistance Malware Troubleshooting will assist you in removing the rogue software from your computer. When you have completed following the recommendations in the link you could also try http://www.malwarebytes.org and http://www.superantispyware.com both programs are free and catches a lot of stuff. You may need to download these programs to a usb stick and I suggest you rename the download file and installation folder to something you can easily remember as malware is written to self protect itself so that by renaming the files the malware won't see it as a threat. After installation check for the latest updates and run the program and let it clean everything it finds and reboot the computer. Do the same for the other program and let us know how this works for you.
Thanks. Malware bytes worked a treat. Some people deserve a good $£%^ing for making these problems
