So I have been noticing that some really random folders are showing up in c:/ and my external. They have names like: becf73cc0a13c8fc8a992c997eb8d8 and inside there is a little notepad doc that appears to be some sort of log but I can't figure out what or why it's there. Names like: msxml4-KB927978-enu. Can I delete these folders and why do they show up. There are like 20 or so on one and about 10 on the other.
