    Hello guys,
    I apologize in advance for my English, but it’s my second language and I’m not quite sure about all the terms and phrases in this case
    I’m having trouble with the internet. (I know that sounds dumb, but I can’t think of a better way to put it) My computer is connected via Wi-Fi, everything’s fine, I’m connected to the router and the internet, but when I launch a browser (tried Firefox, Chrome and IE – with lot of self-denial) the page starts loading but it lasts for about 20 seconds and then everything stops and won’t work again, until I restart the computer. After that, everything repeats and I’ve already restarted the PC for about 30 times at least.
    I’ve tried everything I can think of so far:
    LAN connection does the same thing
    Checkdisk/scandisk found no problem
    Repair from the original win7 CD did nothing
    CMD line – tried resetting IP, DNS, clearing caches (ipconfig /renew and others – I found those on some forums)
    Searched the whole computer 2 times (AVG) and once even from the safe mode through cmd
    Changing DNS to google or other DNS servers, checked IP match etc.
    No strange processes or apps running in the background and nothing unknown starts during the startup

    I’ve encountered this problem about a week or two ago, but it took about 2 or 3 restarts and it was ok. Until yesterday I’ve only hibernated the computer because of some apps, after couple of days I finally shut it down and the day after, this problem popped up and I can’t get rid of it

    I opened the PC case and there is nothing wrong with neither the motherboard nor the wireless card/adapter
    When I start the PC using safe mode, the internet is fine and other computers in the network work with no difficulties

    The internet connection does not drop or fail or anything (or at least it doesn’t show anything like that)

    In the past 4 weeks I only installed 4 things apart from Win updates – LoL, Pando Media Booster (I’ve tried disabling it and it was good for nothing), update for atube catcher and a driver for wireless card/adapter (which is not even needed for the card to connect, but I wanted to try it just in case)

    Everything in the computer seems fine – the connection signals, that nothing’s wrong and the same thing applies for the wireless card, settings etc.

    I’m using Win 7, using home network (everything was fine for about 2 or 3 years), I’ve tried consulting with university students in this field, but nobody could solve it and there is nothing like let’s say “Nerd herd”, where I could call and get an advice in my country

    I’d be really grateful for any advice and I hope the thread makes sense

    Thank you

    Best regards


    Viktor

    Hi Viktor. Welcome to Computer Help Forums.
    This could be a Browser Hijack.
    You could try clearing history cookies and try updating java.
    If all works fine in safe mode then I suggest trying a system restore first.
    Then doing a full scan in "Safe Mode with networking" with Malwarebytes free version.

    Post what it finds.

    Hi, it seems someone has detected the problem. I've been given an advice to uninstall my av (AVG 2013) and it worked. I used AVG remover and for a while, everything worked, but after installing AVG again, the problem is back (it appeared right after I restarted the computer to complete firewall settings). How is that possible, when every other computer my family uses has AVG 2013 and got no problem, including the computer I'm talking about 'till few days ago?
    (I've checked firewall and there is nothing that could block my browsers...or at least it's not obvious enough for me to see it)

    It may seem an obvious suggestion, but in view of your last post I would try installing another Antivirus program. Avast free addition would be my personal choice, but there are others to choose from. I'd be interested to know if another AV program would have the same effect as AVG is having on your machine.

    Can't say, I wouldn't be interested as well, but the problem here is, that right now, my AV license is paid for for another 2 years and that kinda complicates it
    But I've found the problem behind this. AVG couldn't probably handle a single website - everything went to normal after I closed my saved tabs in Chrome. I guessed, that my AV had a problem with website's content or I don't know, but couldn't solve it, so some kind of cycle appeared and AVG blocked the whole network.
