Can iPhones get viruses? Yes, but the risk is low — here’s how to protect yourself

Published

  • The risk of viruses on your iPhone is very low.
  • To protect your iPhone from viruses, keep your iOS updated and don’t click on suspicious links.
  • If you have a virus, try clearing your browser data or performing a factory reset.
  • Visit Insider’s Tech Reference library for more stories.

Viruses and other kinds of malicious software collectively known as malware hang like a dark cloud over the world of technology.

Security experts warn about the risk of malware on PCs and Macs, and most people run some kind of antivirus software on their desktop or laptop for protection.

But what about iPhones? Are they also at risk? Here’s what you need to know.

Can iPhones get viruses?

In short, the answer is yes, but there is very little risk.

According to Okta’s Vice President of Cybersecurity Strategy Marc Rogers, attacks on iPhones are “pretty rare and tend to be isolated to high value attacks, such as those carried out on behalf of nation states for example the pegasus malware created by NSO Group.”

Raj Samani, Chief Scientist for McAfee, agrees. He also says that attacks on iPhones are much rarer than attacks on Android devices.

Androids have a much more fertile environment for malware because there are so many versions of the OS in the wild, and it’s the carriers not Google that get to decide when or if the operating system is patched with security updates on specific model phones.

In contrast, Apple device owners update their operating system software far more frequently, and Apple doesn’t have to deal with the same amount of OS fragmentation found within the Android ecosystem.

The so-called walled garden, another term for Apple’s approach to requiring third-party apps and services to be specifically approved and vetted through the App Store, effectively prevents malware from taking control of the entire phone.

Note: The number of potential viruses that could affect an iOS-based device is minuscule compared to the tens if not hundreds of thousands of known viruses for PCs.

Yet however small, the threat of iPhone viruses is still very real. Samani says that he frequently sees examples of malware that does infect iOS devices, often delivered via email or SMS messages.

Samani considers the most serious threat that iPhones do face to be fake apps apps that pose as other, legitimate apps for nefarious purposes and phishing attacks, which trick users into giving various account information to bad actors.

Protecting your iPhone from viruses

Though the risk to the average user is quite low, there are still precautions that you can take – and, thankfully, most require little effort.

Both Samani and Rogers recommend that you avoid “jailbreaking” your phone. Jailbreaking is an unauthorized change to iOS that allows you to install apps that aren’t found in the official Apple App Store.

“Consider [and follow] the cyber hygiene measures you would apply to all platforms,” Samani says. Rogers also agrees that keeping your iPhone up to date is key.

Samani also recommends that you don’t click on suspicious links that you may receive as these could very well be phishing attempts. Rogers recommends only installing apps you trust from developers you trust.

If you feel like you may be at risk of iPhone viruses, Rogers suggests using more than one device and to “keep different personas (such as work and personal life) completely separated to reduce exposure further.”

How to check an iPhone for a virus

According to Rogers, it is difficult to give specific advice as all viruses are different. However, both Samani and Rogers did give some usual signs of malware that you can look out for, which include:

You notice a sudden increase in suspicious messages.

You notice apps installed that you did not install.

Your iPhone is running slower than usual.

Random messages appear, such as unexplained calendar appointments.

You experience unusual behavior, such as a decrease in battery life or significant unexplainable data usage increase.

However, as Rogers notes, “none of these things are definitive and all can also be caused by perfectly normal events during usage.”

Quick tip: Some apps can scan your device for viruses or help avoid malicious sites, but these should only be used from trusted and reputable vendors as they could be scams. Examples of apps by reputable vendors are Norton 360, McAfee Security, and Malwarebytes.

How to get rid of a virus on iPhone

If you suspect that your iPhone may have been infected with a virus, there are some steps that you can take in order to remove it.

“There are a multitude of security programs available, but it is important to use a reputable company and via the official app store,” Samani says. “These apps will typically offer additional features that will secure the experience such as VPNs and safe searches.”

If you believe that you got the virus after clicking on a suspicious link in Safari, clearing your browser data might remove it. Here’s how to do it:

Open the Settings app.

Tap on Safari.

Tap on Clear History and Website Data and then tap Clear History and Data.

Quick tip: Other browsers have different directions for clearing their cache. See our guide on how to clear your cache on Google Chrome. For Firefox, tap on the three horizontal bars in the bottom right, tap Settings, tap on Data Management, and select Clear Private Data.

According to Rogers, you should also try to restore your iPhone from a previous backup. If that fails, then factory reset your device and it should wipe your iPhone clean, virus-free.

Which assumption is often realistic for a firm in the short run

Published

By

What distinguishes short run cost from long run?

The main difference between long run and short run costs is that there are no fixed factors in the long run; there are both fixed and variable factors in the short run. In the long run the general price level, contractual wages, and expectations adjust fully to the state of the economy.

What distinguishes the short run from the long run for a firm?

“The short run is a period of time in which the quantity of at least one input is fixed and the quantities of the other inputs can be varied. The long run is a period of time in which the quantities of all inputs can be varied.

What is the marginal product of an input in the production process?

The marginal product of an input is the amount of output that is gained by using one additional unit of that input. It can be found by taking the derivative of the production function in terms of the relevant input.

What is average fixed cost curve?

The average fixed costs AFC curve is downward sloping because fixed costs are distributed over a larger volume when the quantity produced increases. AFC is equal to the vertical difference between ATC and AVC. Variable returns to scale explains why the other cost curves are U-shaped.

What distinguishes the very long run from the long run?

Short run – where one factor of production (e.g. capital) is fixed. This is a time period of fewer than four-six months. Very long run – Where all factors of production are variable, and additional factors outside the control of the firm can change, e.g. technology, government policy. A period of several years.

What distinguishes the short run from the long run quizlet?

Which of the following distinguishes the short run from the long run in pure competition? Firms can enter and exit the market in the long run but not in the short run. A constant-cost industry is one in which: resource prices remain unchanged as output is increased.

Why is short run average cost curve U shaped explain?

Short run cost curves tend to be U shaped because of diminishing returns. In the short run, capital is fixed. After a certain point, increasing extra workers leads to declining productivity. Therefore, as you employ more workers the marginal cost increases.

What is average fixed cost of a firm?

In economics, average fixed cost (AFC) is the fixed costs of production (FC) divided by the quantity (Q) of output produced. Fixed costs are those costs that must be incurred in fixed quantity regardless of the level of output produced. Average fixed cost is fixed cost per unit of output.

What methods can be used to calculate average total cost?

Average total cost (ATC) is calculated by dividing total cost by the total quantity produced. The average total cost curve is typically U-shaped. Average variable cost (AVC) is calculated by dividing variable cost by the quantity produced.

What is short run cost curve?

What is Short Run Cost Curve ? Ashort-run cost curve shows the minimum cost impact of output changes for a specific plant size and in a given operating environment. Such curves reflect the optimal or least-cost input combination for producing output under fixed circumstances.

Which of the following cost curve is U-shaped?

The marginal cost curve is usually U-shaped. Marginal cost is relatively high at small quantities of output; then as production increases, marginal cost declines, reaches a minimum value, then rises.

READ ALSO  How to pronounce cichlid

Why are long run average total cost curves often U-shaped?

It is because of the increasing returns to scale in the beginning that the long-run average cost of production falls as output is increased and, likewise, it is because of the decreasing returns to scale that the long-run average cost of production rises beyond a certain point.

What is short-run example?

The short run in this microeconomic context is a planning period over which the managers of a firm must consider one or more of their factors of production as fixed in quantity. For example, a restaurant may regard its building as a fixed factor over a period of at least the next year.

How are the short-run cost functions of the firm estimated?

In the short run, one or more inputs are fixed, so the firm chooses the variable inputs to minimize the cost of producing a given amount of output. … Then we evaluate the cost of K, L, and Land to get the total cost function.

Which factors are used in short-run production process?

The term “short-run production” refers to a production cycle in which at least one factor is fixed. Most companies have multiple factors that they use to produce goods or services. Also known as input factors, they can consist of labor, materials, equipment, capital and real property.

What is the short run production decision of the firm?

Implications of a Shutdown

If the market conditions improve, due to prices increasing or production costs falling, then the firm can resume production. Shutdowns are short run decisions. When a firm shuts down it still retains capital assets, but cannot leave the industry or avoid paying its fixed costs.

SHORT-RUN PRODUCTION ANALYSIS: An analysis of the production decision made by a firm in the short run, with the ultimate goal of explaining the law of supply and the upward-sloping supply curve. … If productivity declines, then more of the variable input is needed as the quantity produced increases.

What happens in the short run?

The short run is a concept that states that, within a certain period in the future, at least one input is fixed while others are variable. In economics, it expresses the idea that an economy behaves differently depending on the length of time it has to react to certain stimuli.

What is short production?

Production is the process of combining various material inputs and immaterial inputs (plans, know-how) in order to make something for consumption (output). It is the act of creating an output, a good or service which has value and contributes to the utility of individuals.

What is short run in perfect competition?

The short-run (SR) supply curve for a perfectly competitive firm is the marginal cost (MC) curve at and above the shutdown point. Portions of the marginal cost curve below the shutdown point are not part of the SR supply curve because the firm is not producing any positive quantity in that range.
