有时一开机就这样，有时是突然性的。硬盘灯突然狂闪，系统运行变得很

缓慢，硬盘可用空间不断的减少，减到一定程度又恢复，接着又是不停的减少

，反复几次就好了，使得我刻碟子的时候也提示内存不足，但有时是什么程序

都没运行就出现此种情况，这对硬盘有伤害否？是不是病毒？用瑞星查不出来

，我的瑞星更新时间是8月22号。

请问用什么工具扫描日志？

今早开机硬盘狂响，之后硬盘灯不亮了，可是系统也没反应了，强行重启几次恢复，今天下载了卡巴斯基没查出问题。之后发现用杀毒软件查较大的文件时就会出现这问题，直至硬盘空间减少到几十KB后恢复继续减少，以前从没这种现象，我记得前两天用BT时调整过磁盘缓存，是不是和虚拟内存有关？该怎么调整？？谢谢！

那么是不是虚拟内存的问题呢？

应该不是sharan吧

我不记得怎么来的了。
刚在网上查了，说是病毒或疑似间谍程序，请问怎么杀？查不出毒来！谢谢了！！

刚才用C:\program files\newdotnet自带的卸载程序把这玩意卸了，重启了一次进程里没了。
可是刚在C盘下的一个名叫KV-BACK的文件夹下查毒，查出一堆木马，文件夹的图表是回收站的，里面都是*.vir文件，杀掉了，可是给大文件查毒时还是使硬盘空间不断减少，系统变得很慢，难道这是正常的？以前不是这样啊！还有开机进入桌面后没有响应，要很长时间才恢复正常。

我用的是IBM A31笔记本，很多进程是这笔记本自带的，那个Newdotnet进程已经卸载，10项已经去除。
另外请问用什么来修复O23 - Service: Ac12sii4cu - - (no file)？？谢谢啦！

刚查了没坏扇区，现在的问题是我没办法全盘扫描杀毒，否则老往硬盘里写东西，根本慢得无法查下去，我在系统信息里看到总虚拟内存是2GB，可用1.96GB，可是我在属性里调的最小和最大分别是384和768，这是怎么回事？？？难道是我的内存有问题了？
