ITunes won't recognize iPad in Windows 7 64bit

Question

I am posting this in the hope it will help other people who have this problem. I spent 7 months trying to find out why iTunes wouldn't recognize my iPad. The only way it was recognized, is if I uninstalled iTunes and reinstalled it.Once I turned off my computer, the next day when I turned it back on, it wouldn't recognize the iPad.
A month ago I bought a iPad 2, and I had 3 months of phone support. Nothing the technition suggested worked. We went through all the fixes that are documented in Apple's solution pages. He decided to send it up to the engineers. They asked for me to give them about 4MB of info from my computer from various hidden folders. The engineers told him they noticed I had 5 Malware programs and an antivirus program. Also that my chipset drivers were out of date or misconfigured.
They told him to start by uninstalling each malware and antivirus, one by one, keeping iTunes open, but unpluggin the iPad before uninstalling, to see if it connected. I uninstalled the first one, which is called Super Malware, and it didn't work, then I uninstalled Avast (free, it requires a computer restart after uninstalling, so you have to open iTunes again), and I plugged in the iPad, and voila, it worked.
All that time, Avast was keeping my iPad from being recognized in iTunes. A few Antivirus programs interfere with iOS devices. If you are having trouble, try uninstalling antivirus and malware programs, one by one, to see if they are the culprit. It is time consuming doing it one by one, but it's the only way to find the one that is causing the problems. We never got to the chipset problem, so I don't know if that would help anyone, and you should be careful when playing around with upgrading drivers for chipsets. If you do, make sure you know what you are doing.

Thanks! I had the exact same problem. i'd reinstall iTunes and it would work for a sync or two, then nothing. Uninstalling Avast worked!
