ALL AV show active & up to date

about 3 weeks ago, security essentials, malwarebytes, & webroot seemed a little different. i now have an extra partition on my hard drive & a RAM DISK? i can telll the icons for malware bytes & webroot are not the real ones. i wiped my drive & reinstalled windows 7,  but what ever it is , its almost like its alive. reg keys changed, & i have even found manifests it writes stating things as to how it is tricking the system. i never download anything i shouldnt, & have no clue how this got on my PC
