Could a virus be preventing me from installing an Anti-virus?

问题

中文

我的nexus 7最近表现得很奇怪（例如，拼写为例）。我想我会在我的设备上安装lookous，并试图下载两次，似乎下载，但下载完成后应用程序不存在，播放商店再次安装了一个安装按钮。我正在尝试远程下载AVG防病毒（从播放商店使用"安装到设备" 按钮。

如果这不起作用，我还能做什么？

编辑： "遥控安装" 做了工作。没有发现病毒。还有什么可能导致应用程序随机关闭？特别是奇怪的是我试图去设置＆gt;运行应用程序它会将我引导到主屏幕上。现在它不是这样做。只有在RAM中的病毒？

My Nexus 7 has recently been behaving oddly (closing apps unexpectedly for example). I figured I would install Lookout on my device, and tried to download it twice, it seems to download but after the download is finished the app isn't there and the play store has an Install button again. I'm trying to download AVG anti-virus remotely (from the play store with the "install to device" button.

If that doesn't work, what else can I do?

EDIT: "Remote Install" did work. No virus was found. What else might cause apps to close randomly? Especially weird was any time I tried to go to Settings > Running Apps it would boot me out to the home screen. Now it's not doing that. Could there have been a virus that was ONLY in RAM?

您是否尝试过远程安装LookOut，或直接安装的AVG？它有效吗？我在想什么东西为应用程序结束意外关闭，但仍然不清楚。您最近安装了可疑应用程序吗？ Andrew T. 2015-01-07 13:07:15Z, License: CC BY-SA 3.0

不，只有在RAM中没有病毒。可能是您的设备刚刚有其他问题。 Booger 2015-01-07 13:14:07Z, License: CC BY-SA 3.0

Did you try to remote install Lookout, or direct installed AVG? Did it work? I'm thinking of out-of-memory for app closing unexpectedly, but it's still unclear. Did you install suspicious app recently? Andrew T. 2015-01-07 13:07:15Z, License: CC BY-SA 3.0

No, there wouldn't be a virus only in RAM. Likely your device just had other issues Booger 2015-01-07 13:14:07Z, License: CC BY-SA 3.0

如果您的设备未植根，则应用程序是不可能阻止安装另一个应用程序的应用程序。如果它扎根，这是可能的（任何事情是可能的），但仍然很不可能。

底线，它非常非常，非常不太可能是恶意软件从播放商店阻止安装。

要尝试的东西：

尝试直接在设备上安装它（即不要从web推送）。
清除Play Store App

If your device is not Rooted, it would be impossible for an App to block installation of another app. If it is rooted, this is possible (anything is possible), but still very unlikely.

Bottom line, it is very, very unlikely that malicious software is blocking installation from the Play Store.

Things to try:

Try to install it directly on the device (ie. don't push from Web).
Clear the cache and data for the Play Store App

生根会如何实现这一点？ Ryan Conrad 2015-01-06 19:07:16Z, License: CC BY-SA 3.0

当您root手机时，任何可能的东西（rooting是您的设备上的超级级别，绕过大量的安全机制）。底线，生根改变所有规则，并使任何可能的规则。 Booger 2015-01-06 20:28:06Z, License: CC BY-SA 3.0

只需具有扎根设备即可使其成为可能。然后，您需要在系统分区上安装一个应用程序安装，从而替换默认包安装程序，甚至修改Google Play。只有系统应用程序只能安装包，root。 Google Play不依赖于任何其他安装程序，它安装自己的软件包，因此必须修改它。根本不是这个都是所有神奇的事情。 Ryan Conrad 2015-01-06 21:15:23Z, License: CC BY-SA 3.0

足够公平的根。我的评论与如果手机植根于植物，这是可能的（再次，假设恶意代码跳过所有这些箍）。如果手机没有植根，那么这是不可能的。我的观点是，如果手机没有植根，那么这是不可能的，如果它是可能是可能的。 Booger 2015-01-06 21:53:49Z, License: CC BY-SA 3.0

底线，如果手机未扎根，那么应用程序无法停止应用程序安装。如果它扎根，那么这可能是可能的（但不太可能，就像你说）。 Booger 2015-01-06 21:55:10Z, License: CC BY-SA 3.0

How would rooting make that possible? Ryan Conrad 2015-01-06 19:07:16Z, License: CC BY-SA 3.0

When you root a phone, ANYTHING is possible (rooting is a super level on your device, that bypasses a lot of security mechanisms). Bottom line, rooting changes ALL the rules, and makes anything possible Booger 2015-01-06 20:28:06Z, License: CC BY-SA 3.0

Just having a rooted device does not make this possible. You would then need an app install on the system partition, that replaces the default package installer, and even modifies google play. Only system apps can install packages, root or not. Google play does not depend on any other installer, it installs its own packages, so it would have to be modified. Root is not this end all magical thing Ryan Conrad 2015-01-06 21:15:23Z, License: CC BY-SA 3.0

Fair enough regarding root. My comment was relating to if the phone is rooted, this is possible (again, assuming the malicious code jumps through all those hoops). If the phone is NOT rooted, then this is NOT possible. My point was that this is not possible if the phone is not rooted, and MAY be possible if it is Booger 2015-01-06 21:53:49Z, License: CC BY-SA 3.0

Bottom line, if the phone is NOT rooted, then an app cannot stop an application from installing. If it is rooted, then this MAY be possible (but not likely, like you said) Booger 2015-01-06 21:55:10Z, License: CC BY-SA 3.0
