Hello. I'm running G Data InternetSecurity 2010 on a Windows XP Pro SP3 system. I've attached a screen shot of the dialogue I am referring to here. I have a 7 mbps DSL PPPoE connection which isn't exactly screaming and sometimes you tube can't dole out packets with the greatest of efficiency usually due to convoluted routing to the content server. Occasionally when I view a you tube video the entire file is checked before it runs in the browser. For example, if the flv is 75 MB and the connection is, say, 54-60 kB/s, the G Data Checking file... dialogue will pop up and if it takes the next ten to twenty minutes to complete, that's how long it will take to start viewing the you tube video. I sent an inquiry to G Data support and received this response, quickly I might add... from: GDATA Support - USA <removed> to: removed date: Mon, Sep 14, 2009 at 1:26 AM subject Re: [Ticket#2removed6] G Data Serviceanfrage International Dear GDATA customer, Thank you for your inquiry. You must disable the webfilter in order for this to not take action. Thank you. For further questions please add all former correspondence. Sincere regards, removed G Data Software AG Service Closing the G Data Checking download... dialogue will not stop the download. One needs to delete the site cookies and Flash LSOs associated with the content and then close the connection to the server. A somewhat daunting/impossible task for the casual user and tedious even for the propeller head geek. From my experience so far, this behavior exists for all file types. If one downloads a 4 GB ISO then it won't be until the G Data download check is complete for the Windows open/save dialogue to appear. Thus, what is normally click & save & wait becomes click & wait & save. It now seems apparent G Data's intercession of the incoming steam, regardless of the source or format, is absolute - a mixed blessing. While waiting on a full security scan prior to the file being saved, executed or presented is categorically thorough, it presents a "wrench in the cogs" experience for the instant gratification zero effort culture of the Internet, particularly for yoo tooberz. Cheers!
