Q: Can my iPhone 4S get infected with a virus/worm? If so how do I tell and what do I do to get rid of it?

No it cannot be affected with any sorta virus. As it runs on the IOS not the android and it is thirdparty locked. MAC and Apple doesn't have viruses.

Hi Pauline,

There are no known viruses that can infect an iOS device. You need not worry about that happening with your iPhone.

Only if you jailbreak your device you can get such things like viruses etc.

Security vulnerabilities: Jailbreaking your device eliminates security layers designed to protect your personal information and your iOS device. With this security removed from your iOS device, hackers may steal your personal information, damage your device, attack your network, or introduce malware, spyware or viruses.

No.

Are you having issues..?  If so, Clearly state them and the Troubleshooting Steps you have tried to resolve them.

Some of the best minds in computing have come up with plenty of exploits for the iphone (including non-jailbroken versions), but they have never made it into the wild, and Apple is very good about using these studies to patch vulneabilities.

In addition, Apple iPhone doesn't allow for virus scanning utilities anyways.

If you're interested in learning about how you can get "hacked", you should be looking at Wifi and 3/4g security.  It's been a proven, effective method for stealing data without the need for viruses or malware.
