Q: we review your mainstay about preventing “drive-by download” attacks that try to put malware on phones with a Android handling complement (see tinyurl.com/y8e37w4b). How can iPhone owners strengthen themselves?
Joe Schaefer, Colorado Springs, Colo.
A: IPhones aren’t as receptive to drive-by malware attacks as Android phones are. That’s since iPhone users can download usually apps that have been authorized as protected by Apple. Here’s how it works:
Android phones have dual download settings. One environment allows a user to download apps usually from a Google Play store, where apps are ostensible to be screened for malware. The other environment allows apps to be commissioned from any website, either it checks for malware or not.
That second environment also opens adult Android phones to drive-by malware attacks, in that dishonourable websites prompt users to accept app downloads that they didn’t ask — downloads that unequivocally enclose malware.
IPhones are set to concede downloads usually from Apple’s App Store, and consumers can’t change that environment as partial of a phone’s normal operations. Because users can’t download apps from anywhere else, drive-by malware attacks on a iPhone aren’t possible.
However, that doesn’t meant that iPhones are defence to malware. New vulnerabilities in a iPhone’s iOS handling complement are detected periodically, forcing Apple to emanate program rags to strengthen a phones (see tinyurl.com/lael6fo). In addition, some iPhone owners have courted difficulty by regulating special non-Apple program to “jailbreak” their phones. Jailbreaking allows an iPhone to download and implement apps from non-Apple websites. But it also disables partial of a iPhone’s confidence software, withdrawal a phone exposed to many forms of malware attacks.
Q: I’ve always close down my Dell Windows 7 PC by regulating a “shut down” command, or, if we have a problem, by forcing a PC to close down by pulling and holding a energy button. But now my PC mostly can’t find my Wi-Fi router (only 4 feet away) unless we restart a PC several times. we attempted restarting a router and modem, though it done no difference. What can we do?
Luke Parmelee, Columbus, Ohio
A: Windows needs to be close down in an nurse way, and your forced shutdowns have substantially shop-worn a handling system. If we have a Windows designation hoop or complement scold disk, try regulating Windows 7 (see “How to run a repair” during tinyurl.com/y7f5e2kg).
If we don’t have those disks, buy a new duplicate of Windows 7 ($115 to $140 during tinyurl.com/y8h9j5f6 and tinyurl.com/y8t3vas2). Before installing it, behind adult your information to a peep expostulate or outmost tough drive, since a routine erases all on a tough disk. You will need to reinstall program we combined to a PC, afterwards duplicate your information behind to a tough disk.
For simplicity, and since we have an unreliable Wi-Fi connection, buy Windows 7 on a DVD disk, not as a download. Make certain we buy a scold (32-bit or 64-bit) chronicle of Windows 7. To find out that your PC uses, go to Control Panel and click System.
