Kaspersky prevents internet connectivity???

    After deciding to part company with Norton antivirus 2002, I was able to
    uninstall it using add remove programs without incident.

    Before uninstalling I chose my next antivirus program: Kaspersky.

    After the installing NAV, I disconnected the cat 5 cable from my modem
    (Roadrunner cable). I then installed Kaspersky, rebooted and
    reconnected the Internet cable. I had no connectivity.

    A few boots later, I called my ISP, Road Runner, and attempted in many
    ways to get a DNS address -- always unsuccessfully.

    I finally uninstalled Kaspersky and suddenly I had connectivity again.
    Not believing this was really possible, I tried it again only to have
    the same thing occur.

    Has anyone ever heard of Kaspersky interfering with Internet
    connectivity and the acquisition of a DNS?

    BTW, I'm now running a trial version of F-Secure Antivirus and it seems
    to be going fine.

    Kaspersky has network attack protection that is basically a firewall which
    you can disable if you use a different firewall. What you could do is leave
    your modem connected and enable Windows firewall if you are running WinXP
    and then during the install of KAV there is an option to disable the network
    attacks by un checking use recommended options then it will take you to
    where you can disable it. Hope this helps.

    Thanks for explaining this.

    It would have been really nice if that had been prominently displayed
    somewhere. It would have saved me and Road Runner a lot of grief.

    What do you think of F-Secure Anti-Virus? I'm running Sygate firewall.

    Check TCP/IP settings for your connection, Advanced Button, navigate to
    Options tab, TCP/IP filtering Properties. If Enable is checked, first
    set all buttons to Permit All, then uncheck the Enable button.

    Thanks for the replies. I did indeed find the tcp/ip connections all
    wrong and couldn't fix them - they kept going to the Windows default
    which wouldn't work. I've uninstalled Kaspersky. I don't want
    something that causes that much trouble.

    See my new post about Avast :)

    If you cannot set "Permit All", then you should consider re-installing
    the OS, having XP SP2 available on CD. Kaspersky is not the problem.

    Even if you have only a single PC connected to internet, buy a NAT
    router with firewall. Your problems will likely disappear.

    KAV has one of the best detection engines out there when it come to Trojans.
    I have had a lot of problems with other AV's missing viruses and had to
    return to a customer to remove them. Since I have been installing KAV on
    there computers I have not had any return calls. So my fingers are crossed I
    won't have a return call. They tell me that KAV has detected viruses since I
    have installed it. It has been about 18 months I have been installing on
    other computers.

    I have a Linksys router and it was active when all the problems
    occurred. It may very well be some oddity on my system but I'd rather
    use a different AV than reinstall windows and all the many utilities,
    settings etc. that I've configured over two years.

    I defrag, clean the registry (JV16) and generally take the time to
    maintain the system.

    What I am shocked about is how much faster the whole system is without

    How much more of a risk am I taking by using Avast rather than

    I'm using Avast now. I'm using a trial version of the Pro version
    because I want script blocking for the occasional times I use IE. I
    have all MS firewall stuff turned off and would rather keep it that way.

    I agree, sofar, Avast is awesome and has almost no impact upon the speed
    of my machine.
