    I attempted to access the internet this morning and every time I try to
    connect to a web page it the adress shows as microsoft.com system guardblock
    or something close to that. It then gives me an error message that it cant
    connect to that page. Any ideas? I have antivirus software which did a sweep
    and turned up nothing. Help Please!

  2. You are seeing the effects of a hijackware infection!

    NB: If you had no anti-virus application installed or the subscription had
    expired *when the machine first got infected* and/or your subscription has
    since expired and/or the machine's not been kept fully-patched at Windows
    Update, don't waste your time with any of the below: Format & reinstall
    Windows. A Repair Install will NOT help!

    1. See if you can download/run the MSRT manually:
    http://www.microsoft.com/security/malwareremove/default.mspx

    NB: Run the FULL scan, not the QUICK scan! You may need to download the
    MSRT on a non-infected machine, then transfer MRT.EXE to the infected
    machine and rename it to SCAN.EXE before running it.

    2. [WinXP ONLY!! =>] Run the Windows Live Safety Center's 'Protection' scan
    (only!) in Safe Mode with Networking, if need be:

    3. Run a /thorough/ check for hijackware, including posting the requested
    logs in an appropriate forum, not here.

    If these procedures look too complex - and there is no shame in admitting
    this isn't your cup of tea - take the machine to a local, reputable and
    independent (i.e., not BigBoxStoreUSA) computer repair shop.
