Nothing alarming, except you are not using the best scanners to find possible troubles. AVG 7.5 was discontinued over a year ago. SpyBot has never been more than a simple cookie removal tool and it seldom finds any true evil investations.
You might want to tell us the problem.
You also might wish to uninstall AVG 7.5, and try, instead, Avira Antivir or Avast as your antivirus program, and SpySweeper, Spyware Doctor, or similar high end paid spyware program or the excellent and free MalwareBytes and SuperAntiSpyware, as well as the free Microsoft program Windows Defender.
All are available by download.
Perhaps you will have some luck there.
