Solve : Wired and wireless internet not working, and more...?

Answer»

Hi!
Classic problem: internet not working. But I think it is more than "classic".
I have an Acer Asipire 5742-6643 Laptop, and since 2 days, wifi AND wired internet connection isn't working. Windows says that the network I'm conected have internet access. But Google Chrome can't access internet (DNS_PROBE_FINISHED_NO_INTERNET), Malwarebytes can't update, Internet Explorer crash at startup. BUT Windows Update CAN update, and Bitdefender is ok too  And I can Ping on command prompt

I scanned with Malwarebytes and Karpersky Rescue Disk. No threats

It happen after Bitdefender found a virus in a legit software (Babyware from Paradox). COINCIDENCE? 

Specs:
Acer Aspire 5742-6643
Windows 7
Intel Core i5-480M

Thanks!!!


P.-S.: English is not my native language. Sorry if I made mistakes 


EDIT: New weird thing; Windows Update keeps installing the same update since yesterday (KB954430, about security for Microsoft XML Core Service Pack 2 for x64 CPU). Windows Update's bubble pop to notify a new update, so I accept. After a successful installation, the bubble pop again for the same update. In the update historic, this update appear 5 times!

What's wrong with this laptop?! Help please!Please download MiniToolBox to Desktop and run it.

    Here is the results

    [attachment deleted by admin to conserve space]The Minitool box log doesn't show any connection. Have you tried re-setting your router? Have you tried a System Restore to a date before this started?System Restore don't work, even with the antivirus disabled  I reset the modem. This has not solved the problem.

    But when I ran MiniToolBox, I forget to connect to the network (wired)  So here is a new report!

    [attachment deleted by admin to conserve space]There's something here in the log that doesn't seem correct. Could you please check your Device Manager to see if there are any yellow waring icons.

    You are right. There is a warning icon on the Virtual WiFi Miniport Adaptater  Windows has stopped this device because it has reported problems (Code 43)

    I googled and found this: http://technet.microsoft.com/en-us/library/cc725873(v=ws.10).aspx Should I FOLLOW these steps?Yes, go ahead and GIVE it a try.I unistalled the device and his driver, then install back. The warning icon is gone ("This device is working properly"), but still no internet access  Ok, run the MiniToolbox again and I TAKE another look at the log.Do you want me to run it on WiFi or wired connection?Hi! I ran the MiniToolbox on WiFi and on wired connection.

    I suspect the modem to be the source of the problem, because since 2 days internet is slow on almost every device in the house (tablet, SMARTPHONE, PC). I tested with Speedtest.net and I get ping of 1500ms (normal: 30-40ms) and speed of 1.2mb/s (normal: 4-5mb/s). I tested on almost every device. Only one device has a normal speed.

    The modem is a modem-router TP-Link TD-W8960N v1 and it is 3 years old.

    [attachment deleted by admin to conserve space]I'm still not seeing any connection on both logs. It must be the modem. Did you reset it?Yes I reset it 2 days ago.is there any chance of trying another computer or laptop on that modem?
