Have you tried rebooting it? Did the AV scanner come up with anything? When did this start (update, system change)?

Is there an AV scanner for Adroid?

There is the possibility that you downloaded a &quot;legitimate&quot; app, but it just so happens to be spamware. (I tend to think a bit more dire when I throw around the word &quot;virus,&quot; but I'm probably just playing semantics.) Have you (or someone who has access to your phone) downloaded any new apps recently?

I keep seeing icons appearing on the home screen of my Nexus 7. &nbsp;One is a link to an &quot;Newest Apps&quot; promotional webpage. &nbsp;Another is a whole slew of &nbsp;links that take me to the Google Play screen for a game I'm not interested in. There was also one for Expedia.<br />
<br />
I remove the icons by dragging them to the trash can, but the next day I go to my home screen and there they are again.<br />
<br />
I must have some sort of infection, but I don't know how to go about detecting it.<br />
<br />
Can anybody help me on this?<br />

Operating system security (OS security) is the process of ensuring OS integrity, confidentiality and availability. OS security refers to specified steps or measures used to protect the OS from threats, viruses, worms, malware or remote hacker intrusions. OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised, including authentication, passwords and threats to systems and programs.

OS Security

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.

A vulnerability is a weakness which allows an attacker to reduce a system's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness, known as the attack surface. Vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities. Other vulnerabilities include security risks, security defects and constructs in programming languages that are difficult to use properly.
