菜鸟恳请高手帮忙诊断俺的电脑问题！！！
电脑中毒了，虽然还能正常使用，但有下列现象：
症状一是一开机就出现如下提示：
Buffer overrun detected
Program:C\WINDOWS\system32\RUNDLL32.exe
A buffer overrun has been detected which has corrupted the program’s internal state.the program cannot safely continue execution and must now be terminated.
症状二是病毒隔一会儿就出现一下，虽然每次都成功杀毒，但是个不死鸟。
病毒路径：C:\Documents and Settings\LocalService\Local Settings\Temporary Internet Files\Content.IE5
病毒名称：Trojan.spy.agent.xv
