I just bought a new computer and installed TB on it. For some reason, it very, very slow - if it responds at all. What's ahappened and (more important) how do I fix it?

It's a brand new PC so it's McAfee. Is that the problem? Changing anti-virus software is on my ToDo.

Most likely McAfee is the problem. https://wiki.mozilla.org/Thunderbird:Testing:Antivirus_Related_Performance_Issues#McAfee
