Every time I restart my computer, a red shield icon appears in the bottom right notification window with the following notice: "Check your antispyware software status. Windows Defender is turned off. Click this notification to fix the problem." When I open the Windows Security Center, it shows two things. (1) Windows Defender is turned off. When I click the button to turn it on, it turns on normally and stays on. (2) There is a notice that says my Trend Micro Security program is on but reporting status in a format that is no longer supported. However, my Trend Micro Security program is up to date and working properly.
I haven't seen any other issues with my computer. This issue is merely annoying during startup. I ran Malwarebytes Anti-Malware and Combofix. Those logs and an OTL log are pasted below.
My computer: Dell Inspiron 1720 laptop running Windows Vista Home Premium SP2.
Thanks in advance for any assistance!
