As far as I know, the AVG tune up can be purchase from thier website
https://avg.com and they offer free trial as well, though I have never used any from thier partner website.
AVG TuneUp
speeds up and cleans your PC by detecting and safely
removing bloatware (unnecessary software) from your system. AVG TuneUp also addresses the issues that can cause system crashes and unpredictable behavior, including
junk files, unnecessary programs installed on your PC, outdated software, and unusual system settings.
Over time, the reliability and performance of your PC will decline. You may notice issues such as:
- Programs that run very slowly, crash, or freeze.
- A lack of disk space.
- Pop-ups from “bloatware”
AVG TuneUp optimizes your PC to restore its performance and keep it in top shape
