Tech Support: Computer comes out of sleep mode on its own at various times

Computer comes out of sleep mode on its own at various times

Why would my computer come out of sleep mode on its own at various times?  Should I be worried about malware?  I've looked at the Task Manager for CPU usage and number of processes running, but I'm not sure what to look for.  There's a current version
of Kaspersky Anti-Virus running which automatically updates several times a day, but I don't believe that it "wakes up" the computer.  Don't think Windows Update does this either.  Can power fluctuations cause this?
