Hello guys ,i have a problem with avast but also with avg antiviruses .At first i installed avast then after some time switched to avg.Both antiviruses served me well but at some point i remember i had avg out of date and wanted to update it , however i couldnt do it manually and decided to uninstall it and install avast again.So long story short i am here because i cant update (or install at this point )any of those 2 antiviruses.The thing is that at one point i managed to update my avg by doing something like going in my network or something ip adress (i dont really remember) and i put something numbers like xxxx.yyyy.zzzz that was like the adress of a google server.That was the only way i managed to update avg back then but it seems i cant find how to do it again…I am sorry its super confusing i know,any help would be appreciated.
