Hi I am not sure if this issue has been discussed (as I have been out of the loop lately), but I am wondering if anyone can verify this issue I have been having. In my SpiDer Guard I have check marked the options to scan files by format and then the items for scanning archives and email files as well. With these items checkmarked, whenever I open Opera my system process spikes to 100% CPU usage and stays there. Opera becomes unusable and has to be closed, but other programs do not seem to be effected. For example, I can still use Internet Explorer with no problems using these SpiDer Guard settings. If I uncheck the options for scanning archives and email files, I am able to use Opera with no problems. Not a really big issue for me, I am just wondering if it could be a potential bug. Latest version of Dr.Web and Opera on an updated Windows 2000 Pro computer. Thanks everyone.
