AVG TuneUP is a utility software designed to clean up your computer, which, over time, will accumulate tons of junk files, registry mis-matches, dead shortcuts, and well, basically just a bunch of "sludge" that sits in the background slowing your computer down. This aims to help clean it up, and in theory, speed up your computer.
I decided to try it on a Windows laptop that I had updated from Windows 8 to Windows 10, since updating usually leaves scattered files and junk behind on a system. I downloaded the installation which took quite a while to install once it downloaded. Eventually though, it began to run.
The first time you run it, it wants to do a scan, which will look for any issues you may have in your registry files, shortcuts, junk files, clutter in your browsers, cookies in the browsers, and history of where you've visited, etc. The scan started going down the list, but then a bug showed itself - the screen just closed. It didn't minimize... it literally just closed. Then, the icon for the program disappeared from my desktop, and it didn't even show up under my "all programs" area - it was as though it literally uninstalled itself right in the middle of a scan. About two minutes later, suddenly, it re-appeared, icon, scan screen and all, and has finished it's scan (??). I have ZERO idea what could cause a program to literally disappear yet still be running, and then re-appear again. But, it was there and still working.
It found issues in every category. You need only to tell it to continue after the results are displayed, and it "fixes" each one. You can then see a dashboard screen which allows you more control over things like just speeding up the machine, freeing up space, fixing problems, etc. It fixed my issues, but then, bug number 2 - it showed that it had started another scan again. I went into the scan screen and it just showed a small, spinning, icon which I could not pause or stop. This continued for over an hour and nothing I did would stop it. Closing the computer and restarting it had the same results, as did rebooting the laptop entirely.
Now - did it work in terms of speeding up the laptop? I think it did to some degree. I noticed a few things being a bit speedier when I used them. The registry cleaner part did not seem to do any damage - all was well on that front. I'm just not sure with the bugs as they are if I could recommend it, though. Programs "disappearing" mid-use, re-appearing, and starting parts of their applications on their own and never ending, concern me.
Again, it's maybe a glitch, or maybe something that can be fixed with updates, so I won't say "don't buy it" as it did seem to improve the laptop. But I do caution that you might experience bugs a long the way.
