I've been using DrWeb Antivirus for a while now with no problems. I now have received a new computer and I have retired my old computer. When I install DrWeb on my new computer I get a blue screen of death when Spider Guard tries to start. The info from the blue screen is as follows. IRQL_NOT_LESS_OR_EQUAL STOP: 0x0000000A (0x00050000, 0x000000FF, 0x00000000, 0x805c88AE) This blue screen happens whenever I try and load Spider Guard. I configured it to not load at startup and tried loading it once Windows has started but I still get the same blue screen of death. This problem is occurring with DrWeb version 4.29a. I had an older copy of 4.28c scanner version 4.28d. I installed it and and it works fine but I have a problem when I try and update to the latest virus signatures. It also downloads the latest version 4.29a and then I'm back to the blue screens. How do I manually update the virus signatures? Please be as specific as possible. The specs for the computer is as follows. P IV 3.06GHz with HyperThreading. 1024mb DDR SDRAM at 333MHz. ATI Radeon 9700 128MB DDR. Integrated NIC. WinXP SP1 with all the latest service patches. Any help with this problem is appreciated.
