My backup battery is about dead (have a replacement but haven't installed it yet). When I booted up today everything reset to the default when I bought the pc. When the boot up finished, I reset the time and date, but now the NOD32 v. 4.0 logo is red and Nod tells me I may need to update my virus definitions. I've done so, but the logo in the lower right remains red. At the same time, I'm being informed that my virus definitions are current. Also MS Windows Security Center is given me a warning that my antivirus may need updating. I assume I'll have the same problem after I replace the battery. How do I convince NOD32 and Windows Security Center that I'm current with my updates? Thanks for any help.
