An important registery change, possibly a virus?

[chaser-the-wolf]

Ok, so i was starting up my computer, all my programs loaded, including Spybot S&B(Including tea timer, which is So post to be off, Resident didn't load though...), Anyway, i got this here pop up:

For those who can not see the image:

Spybot - Search and Destroy has detected an important
registry entry that has been changed.

Category: Season Manager
Change: Value Added
Entry: Bootexecute
Old data:
New data: Autocheck autochk *\
[o] Remember this decision
[Allow change] [?] [Deny change]
----------------------------------------------------------------------------------
What is this? should i allow the change or deny it? Is this something i should be worried about(because Tea timer does freak me out when it pops these messages up........ a lot......)

UPDATE: POSSIBLE AWSNER

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager

Data type Range Default value

REG_BINARY Command or executable program autocheck autochk *

Description:
Specifies the applications, services, and commands executed during startup.

For example, if Convert.exe has been used to convert the file system on a hard disk drive, you can add the following command to BootExecute to convert the file system when Windows 2000 is restarted:

BootExecute = autocheck autoconv \DosDevices\x: /FS:NTFS

Note:

Do not delete the default value, autocheck autochk *, from the value of BootExecute. To prevent Autochk.exe from running on specific volumes or from running at all, use Chkntfs.exe.

Tip:

For more information on Autochk, Chkntfs, and Convert, see the Microsoft Knowledge Base link on the Web Resources page. Search the Knowledge Base using the keywords Autochk, Chkntfs, and Convert.
