    I have tried to exclude all Picture files from being scanned, but it seems to scan them anyways.

    Im on 56k, so if i visit a page with a lot fo pictures, IMON doesnt let any of them start partially loading on the screen, i have to wait until they are 100% complete, slowing my browsing speed down massivly.

    It doesnt seem to recognise i have unticked the scan all files, and that no Graphic extensions are present in the list of extension to scan.

    Anyone help? For now i have had to turn it off so i can browse at an acceptable speed on sites with mass pictures, ot a few large pics.

    Just put IE or whatever browser you're using in Higher compatibility mode.

    Even if IMON shows jpg files as scanned in its status window, they only pass the scanner without being actually scanned. Please read the difference between active and passive mode. You can try setting your browser to work in passive mode which will make downloading faster, however, in this mode some viruses may slip thorugh IMON.

    Passive (compatible) mode:

    IMON running in passive mode stores a copy of each downloaded file while each received packet sends out directly to the application (browser). When the end of the file is detected, the whole file is checked for viruses and the local copy is subsequently deleted.
    Given the principle of work in this mode, IMON can only partially intercept incoming file by terminating the connection before sending out the last fragment of the file. In case the browser allows fragmented file downloading, it can request the missing fragment from the HTTP server resulting in that IMON will become ineffective. Therefore, IMON has mostly a notification function in passive mode.

    This mode is suitable for applications with a little probability of downloading a malicious code, applications which utilize the HTTP protocol only as a facilitating mean and are not primarily intended for downloading files (e.g. on-line multimedia players). Other application categories requiring passive mode are various download managers/accelerators which utilize the HTTP protocol in a specific way not usually compatible with active mode of the HTTP scanner.

    Active mode

    In active mode IMON stores each downloaded file. The main difference is that no file fragment is sent to the application during the download process. The whole file is sent to the application after it’s been checked for viruses. In case the file contained a malicious code, an html page informing the user about the infiltration is sent in place of it.

    Active mode is intended for applications of which primary role is downloading files and html web pages from the Internet (e.g. web browsers). IMON running in active mode can, in most cases, prevent malicious code from entering the computer. Under certain circumstances, a malicious code can slip through IMON even if working in active mode (e.g. if the download process is interrupted and the browser sends out a request to download the missing file fragment, IMON will not get the file in its entirety and is unable to check it).

    Side effects
    Using the HTTP scanner in active mode may have several side effects resulting from the way of checking. Given that the whole file is received by IMON first and then, after it’s been checked, sent to the application, the application will not provide accurate information on the download progress. That’s because no data is coming from the application’s point of view (the phase when the file is being downloaded by IMON) and the whole file will be delivered at once. The difference is noticeable especially when downloading larger files.
    So that the user can see the current download progress, a small IMON’s window will show up after 5 sec. in the lower-right corner of the screen. Right-click the window to invoke a context menu to display detailed information on download progress, terminate download or switch to passive mode. For proper functioning of some types of applications active mode is not suitable (e.g. multimedia players which need to know the beginning of a file before the whole file is actually downloaded or applications which utilize the HTTP protocol in a specific way such as download managers). For such applications, it is necessary to set passive mode.
