谁能告诉我，这是什么怪现象？
在我的最后的一个硬盘分区T上，随时间推移，出现一些随机名称的文件夹，经检查好像不是病毒，但相同内容，不同文件夹名称的东西与日俱增，占用硬盘空间，而且子目录support和update里面的文件还不能用通常的方法删除，必须用工具软件才可删除掉，我都被折磨得要崩溃了。
1、硬盘分区T上的随机名称的文件夹如下所示：
2009-12-16 12:01 <DIR> 16b7011327d2f97c5e646cdc3cd079
2010-01-08 12:01 <DIR> 1be4b9ac053031772103e1b1
2010-01-18 12:01 <DIR> 30aa0b6ac4bae7f1bc
2010-01-14 12:01 <DIR> 66b55ea2876773ba25c077c8edebca
2010-01-06 12:01 <DIR> 696546c234452a5cdf29
2010-01-12 12:01 <DIR> 8acbf8b4a755311c7079b4
2010-01-13 12:01 <DIR> 96f0bf3a90b2dded8d6b51b8a7b9c4
2010-01-09 12:01 <DIR> 98a11d2ca02d58d591
2010-01-11 12:01 <DIR> a3e1026e1d0ac2cbcb1fb1cf
2010-01-17 12:01 <DIR> af1d6e5e0bba61633c37913591440ea0
2010-01-05 12:01 <DIR> c0e92375e139a04a72
2009-10-31 12:01 <DIR> c52ea4da956210530be906b8f2e1
2、每个文件夹里的内容都相同，以c0e92375e139a04a72为例：
