I can watch the file appear in the appropriate folder and stay. I can even right-click and view the properties. However, as soon as the download reaches 100% it disappears, and can not be found even with an advantaged search that looks in both hidden and system files. I also can download updates, but they too disappear in the same manner. I have Windows Vista Home Premium x32 service pack 2. I believe it is a virus, but have not been able to identify or locate its location

I have the same issue... Magon Liu...this is not for a particular file, any file I download has the same behavior. It doesn't matter if I download it via IE90, chrome or mozilla. I can see the file in download folder, as soon as download reaches 100% it gets deleted. It doesn't go in the recycle bin. Really really frustrating. Thank you

I have the same issue, any file or program I download is deleted before I can view it.. Jack
