Can't connect to internet??
« on: February 17, 2018, 05:27:59 PM »
This happens to me twice for the last two days already. I was downloading games from wargaming.com and so I leave my computer running before I went to bed. Next morning I get up, I saw the downloads stoped and the network icon show a exclamation mark on it.

I tried to reboot my computer and my router. NOT WORKING.

I check my iPad and iPhone, the internet is working on these two.

After I uninstall Avast free anti-virus, the internet is working.

First I think I might chang some setting by accidently and casue the Avast close my internet.

I install the Avast free anti-virus again and do not change any setting and keep downloading games from wargaming.com.

After a few hours(probably 8 or 9 hours, or longer. ), my internet stop working again.

This time I uninstall Avast right after I find my internet stop working.

My internet is back to normal after Avast is uninstalled.

- Which Avast..? (Free/Pro/IS/Premier)
Avast free anti-virus (I have mentioned it in my post)

- Which version..?
I don't know the version when I first encounter the problem. However, the second time I downloaded directly from the Avast homepage. So it should be the latest version

- OS..? (32/64 Bit..? - which SP/Build..?)
Win10, 10.0.16299, build 16299, 64bit, Home version.

- Other security related software installed..?
only the build-in windows defender and CCleaner free version but CCleaner is used for cleaning registry and disk space.

- Which AV(s) did you use before Avast..?
I can't remember. after I bought my computer, I uninstall everything and install Avast immediately.

First, be sure to get rid of all remnants of your prior installed AV(s)..!!
-> https://support.avast.com/article/11/

Then:
1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions..!!)
3. Reinstall Avast with the downloaded installer from point 1.
4. Reboot.

I tried your method several times but still not working. Every time the internet stopped working, I uninstall avast immediately and internet is back to normal.

Unfortunately, there's no additional support (Email/Phone) for Avast Free.
But you can wait for one of the guys with W10, maybe they can help...

to bob3160

I didn't install any extra firewall, and I don't remember I have installed any other AVs. If there was any other AVs came with my PC, I can't remember.

Anyways, now I switch to zonealarm and everything is fine so far. thanks bob3160 and Asyn for helping out ;D ;D
