我的机器配置：
ＣＰＵ：塞扬２.４Ｇ
显卡 ：塞科４４０ＭＸ（６４Ｍ显存）
内存 ：ＤＤＲ２５６Ｍ
硬盘 ：ＷＤ８０Ｇ
主版 ：技嘉８４５ＥＧ
从５月份就开始出现下列症状：
１ 开机系统偶尔出现不完整启动（有时提示有的文件找不到）
２ 开机内存被大量占用（每次启动都在３０％以下，我是用超级魔法兔子看到的）
３ 删除硬盘文件时，被删除硬盘空间不能被释放（这个问题直到前几天才发现，已经有５Ｇ硬盘就这么消失了，头疼啊）
我曾经用瑞星 江民 熊猫 金山杀过，但都没找到病毒，但症状依旧存在，我又用反间谍专家也没找到异常，请教高手，我是中了病毒吗？
我的任务管理器里显示如下：
taskmgr.exe
iexplore.exe
ishare_user.exe
SVCHOST.EXE
alg.exe
RavStub.exe
wdfmgr.exe
ctfmon.exe
realsched.exe

希望能给我一个解决这个问题的方法，谢谢大家！！
这里我刚刚学会了弄日志，希望大家能多多给点建议
