Buffer Overrun Detected

  1. Hey everyone.
    Here is an error message I keep getting while running IE 7 and Firefox when I switched to that.

    Microsoft Visual C++ Runtime Library
    Buffer overrun detected!
    Program C:\Program Files\Internet Explorer\iesplore.exe
    A buffer overrun has been detected which has corrupted the program's internal state. The programcannot safely continue execution and must now be terminated.

    I have checked across several forums to see what this error message means and from what I can gather, there is not one definitive source. HiJackThis seems to be the greatest method of dealing with it though. I ran the program and have attached the log. Any help you can give would be greatly appreciated. Thanks.

    Hi and welcome to techspot. =)

    Your system is infected with a lop hijacker, and possibly other malware.

    Download LSPFix from http://cexx.org/lspfix.htm
    1. Disconnect from the Internet, go to the LSPfix file and extract/unzip LSP-Fix into its own folder [C:\lspfix].
    2. Open the lspfix folder and double-click on LSPFix.exe to start the program.
    3. Check the "I know what I am doing" checkbox.
    4. Select (highlight) all instances of 'pctlsp.dll' in the left column under "Keep".
    5. Click the arrow >> so it goes over to the right column under "Remove".
    6. Click "Finish" and LSPfix will remove references to the file and restore the chain numbers.
    7. Restart your computer

    I noticed that you are also running an outdated version of HijackThis.

    AVG Antispyware says No Action Taken for all items. Please set it to remove all items as per this guide.

    You also have not renamed HijackThis. Please do so as per these instructions.

    Then post fresh HijackThis and AVG Antispyware logs.

    Regards :)

    Your HijackThis log is clean.

    Your AVG Antispyware log says no action taken. Please run it again via the instructions in the link I gave before.

    Pleast post fresh AVG Antispyware and ComboFix logs afterwards, just to ensure that the system is clean.

    Regards :)

    It looks now like your system is clean. However, it looks like you're not running any firewall software, which is a security risk. I recommend running either ZoneAlarm or Kerio (free firewall programs).

    Is your system still detecting malware?

    I downloaded ZoneAlarm. Thanks again for all your help, this site is great! Keep up the good work
