uhh, I don't live in the states so do you know of any support center e-mail I could contact? and oh, I googled the problem and seems like people were getting this error back in 2007 and I tried to run the dellfix.bat and still it didn't help.
I did some quick checking but was unable to figure out if you really needed to contact Dell or McAfee. As for Dell, you need to contact their tech support however you normally get in touch with them. You can start with http://support.dell.com.
For McAfee, there is a Customer Service link at the top of the page with more options.
