McAfee and Windows 7 64-bit CRASH!

I have had an ongoing subscription with McAfee for several years and recently bought a new laptop loaded with Windows 7 64-bit. This came with a free 60 day trial version of McAfee antivirus software installed on it which seemed to work fine. When the free trial expired I decided to use my current subscription, (which allowed protection for up to 3 different machines and had used on my old laptop) on my new laptop. When I called McAfee to do this I asked the rep if it was compatible with Windows 7 and I was told that it was. After receiving download instuctions via email I noticed that Windows 7 was not on the list of compatible Operating Systems, just Win 2000,Win XP and Win Vista. I called McAfee back to verify Windows 7 compatibility and again, they assured me that is was fine. So I went ahead with the download. I clicked the RUN button for DMSetup.exe and then RUN for the IE Security warning as per the instuctions from McAfee and the BLUE SCREEN OF DEATH appeared for about 2 seconds and my machine shut down! After attemting to restart it went into Windows Error Recovery mode then Launch Start-up Repair and then could not repair problem and shut down again. This sequence repeated every time I tried to restart. I called McAfee back and again I was assued that it was compatible with Windows 7 and they said I should do an online diagnostic on their site. I told them this was impossible as my machine would not start up even in safe mode so I could not even go online at all! They finally said to contact the maker of my machine as that is where they thought the problem was, which I did. The maker told me that the machine would have to be reformatted after several attempts to get it going. 1 Day and $200.00 later with a reformatted machine I called McAfee again and told them of the crash and that I thought their software was the cause. They advised me this was impossible as their Software is compatible with Windows 7 and that there was no problem in trying to install again. Hesitantly I tried the download again. At the same point in the download the exact same thing happens...shut down. This time thankfully, the system recovered after several attempts. I called McAfee AGAIN and told them they had nearly crashed my machine again! They said my operating system must be corrupt. I told them it was reinstalled only 1 hour earlier so how could it be corrupted? I insisted on talking to a technical rep which they agreed to (and didn't charge me the $9.95 per incedent fee thank you very much). I finally got an explaination after 6 hours, 5 phone calls. McAfee does not have a product that is compatible with Windows 7 64-bit yet. It should be ready in a month or so. They then offered to extend my trial version for an extra 30 days! I said "you just told me there is nothing compatible with Windows 7 64-bit" so what good is it to extend my trial version. Besides I was told to uninstall the trial version before installing the new one so it was gone from my machine. What really confuses me is the trial version worked fine so it must have been compatible with Windows 7 64-bit but the tech rep said they had nothing yet that was compatible???? Needless to say I have cancelled my subscription with McAfee and will NEVER use their products again.....
