I'm not familiar with a netbook with Android, although I've installed Android a couple of times on my Acer 721 11.6" netbook.
I would recommend abandoning Android and installing Linux Mint LXDE, which is a free OS available for free download from linuxmint.com
Linux comes with almost everything necessary to begin using the computer immediately after installing the OS.
To install it on a netbook, I'm assuming you don't have a DVD optical drive so you have to install it from a USB thumb drive.
First download the .iso file on another computer. Use a free program to create a bootable USB using the .iso file. (You can't just copy the file to the USB drive) ... I'd recommend using Active ISO Burner from NTFS.com ... here's the download link ... http://www.ntfs.com/iso-burning.htm
Once you've created the boobable USB drive from the .iso file, you shoud be able to insert it and start the computer and sse the Linux Mint startup screen. It will come up in LIVE mode, without installing itself, so you can try it out.
If you want to install it, make sure you are connected to the Internet and have your AC power adapter plugged in.
If the computer doesn't come up with the Linux screen, you probably just need to reset your Bios boot order so it boots from the USB driver first. Plug in the USB drive and start the computer. Look of instructions for set up or boot order, usually pressing F2 while the computer is starting. Follow the directions to move the USB to the top of the boot devices, i.e. about the hard drive. Save changes and restart the computer. It should now bood from the USB.
When the LIVE mode comes up, it displays the LInux desktop with an Install icon. If you double click the Install Icon you will begin the installation process and just follow the simple prompts and create a password when prompted.
Linux never requires anti-virus and does not become infected. You can visit the main linuxmint.com website and download the .PDF manual if you are interested.
Your computer is probably 64-bit, but if not, there is also a 32-bit version available for download.
The image shown below is from my Acer and is Linux Mint KDE, which is also available from the same website and similar to LXDE, but more full-featured. All Google programs I know of are available for Linux, since Google usese 100% Linux. Android is Linux also.
