So I have an Acer Aspire E1-527G and I had Avast installed. Recently I have had issues with my wireless connection that kept shutting down, and I asked someone who knows (a lot more) than me about the subject, and he said Avast could be a problem. In fact, when I wanted to uninstall it, it would freeze and I had to reboot several times. Eventually I got rid of it and now I just have Windows Defender and the free version of Malware Bytes. This laptop isnt just used by me, and safe browsing isnt always practiced, so I need something (free) that is more efficient than Windows Defender. What do you guys recommend?
