After running antivirus/malware programs the infections are supposedly removed, but they just come back. I have tried running mbam, spybot s&d, and avgfree. I also ran these programs in safe mode. The most noticeable problem these infections cause are browser redirects.

Here are logs from hijackthis and malwarebytes.
