    Hello,

    I am the IT person at a fairly large office which is in the process of upgrading all the computers to F prot 6. However, with the upgrade there is a strange bug which I believe is a false-positive induced crash.

    A lot of people go to sigalert.com to check the bay area traffic, and we have everyone using Firefox as their default browser. With F prot 6 installed, whenever someone goes to this site (myself included), the computer will crash after a few moments (usually after clicking "back" while navigating through the site) and automatically restart. In looking at the dump file, it says that FStopW.sys is most likely the culprit.

    I tried clearing the cache and deleting all cookies and disabling cookies altogether with the same result. There are only 2 ways that it will not crash:

    1. Turn off file system protection on F Prot.
    2. Using IE instead of Firefox.

    After clearing the cache and then only visiting the site (and disabling the file system scan), I looked through my cache to see if I could find the offending file. I found a reference to a .js file with only 1 line of code:

    function DocumentDotWrite(s){document.write(s);}

    Is there anything about this file that might send up a flag with F Prot's heuristic scan?

    It seems like everything else in the cache is either a picture or a google analytics link, or other benign stuff.

    Any help with this strange problem would be much appreciated!

    Thanks.

    Hi jhubsta,

    You should also post this at the f-prot forum to get immediate help from their support team.

    I can confirm the crash on visiting that site and hitting the back button. I also posted on Frisk Forum with a link to this thread.

    I also browsed a bit on 3 different computer using IE7, Firefox (no extension) and XPSP2. Seemed ok with KIS, NIS2007 and AVG security Suite.

    NOD is fine also. So it's just limited to F-Prot I suppose.
