Are these real vulnerabilities and if yes, how can I fix them?

Several identified via a Kasparsky Security Scan - "vulnerabilities" are these serious questions or not?  If so, what should I do to solve?  I use Windows XP SP 3 and, above all, the Firefox browser, although always use Internet Explorer, from time to time.  I use Microsoft Security Essentials and Malwarebytes Pro, which did not identify malicious software or virus problems (or have the Kasparsky scan).

(1) C:\WINDOWS\system32\msxml4.dll
(2) "debugger detected system process.
(3) ' Autorun of drives is allowed.
(4) ' Autorun for network drives is enabled. "
(5) "CD/DVD autorun is enabled.
(6) "support removable autorun is enabled.
(7) ' Windows Explorer: showing extensions of known file types is disabled.
(8) ' Windows Explorer: view the extension of known file types ".

Thank you!

Is there a help function of some sort with the Kaspersky product that explains these messages?  And does not offer the KSS to 'correct '?

These elements are "vulnerabilities" because they allow a behavior potentially at risk, although some of them appear to be riskier than others.

For example, many business computers are configured to prevent the operation with removable media (aka flash readers) to prevent malware carried on a USB key to infect computers as soon as you plug it autorun in.  On the other hand, it seems far less likely to me that CDs and DVDs would be as risky as flash drives.  See http://lifehacker.com/5858703/disable-autorun-to-stop-50-of-windows-malware-threats
Some other entries are mechanisms that malware could use, even if the item itself is not malicious software (msxml4.dll and debugger process system).  For example, in 2006, Microsoft released a security fix for msxml4.  If you did not keep your system up-to-date by using Windows Update, maybe you have the old version of this.  Or maybe Kaspersky think that there is a new problem.  See http://technet.microsoft.com/en-us/security/bulletin/ms06-071

If the display of the extensions of known file types is disabled, the malware can dress up with an innocuous name.  For example, a file named Readme.txt is obviously some sort of information.  If the display of file extension is disabled, it will appear as simply readme - and might actually be readme.exe, so if you clicked on it, instead of opening a file in Notepad for you to read, you can proceed with the installation of some malicious software.
