I was using avast free version for a long time, however recently when i tried to share my internet through wifi to phone it caused problems (I can connect but can't browse or download in phone). I had to uninstall avast to make shared internet work on my phone. So I was thinking, would it be adequate to just update windows defender and use it as my sole antivirus software? I know it doesn't have looks and features of avast but can it keep my computer safe from viruses? Btw I''m using windows 7 home premium sp1. Thank you
