00:00Hey everyone and welcome back to the channel. Today we're diving deep into a topic that's
00:05more important than ever, digital security. How can you be sure your phone or computer
00:10isn't compromised? We're going to walk through a full security audit step by step to help
00:15you hunt down potential spyware or vulnerabilities on your devices. This is for educational purposes
00:21to empower you to protect your digital life. First things first, let's talk about the initial
00:26signs of trouble. Is your device suddenly running incredibly slow? Is the battery draining much
00:31faster than usual? Are you seeing unexpected pop-ups or apps you don't remember installing?
00:36These can all be red flags. Another big one is increased data usage. If your data consumption
00:42has skyrocketed without a change in your habits, something might be running in the background and
00:47sending information out. Keep an eye on these symptoms as they're often the first clue that
00:52something's amiss. All right, let's get hands-on. We'll start with your mobile device, whether it's
00:58Android or iOS. The first place to check is your list of installed applications. Go through it
01:03meticulously. If you see an app you don't recognize or one that looks suspicious, investigate it. A quick
01:09search online for the app's name can reveal if it's known malware. On Android, you should also check
01:15your device administrator apps. Go to Settings, then Security, and find Device Admin Apps. Suspicious apps
01:21will sometimes grant themselves admin privileges to prevent you from uninstalling them. If you see
01:26anything there that shouldn't have that level of control, like a simple game or utility app,
01:31that's a major warning sign. Disable its access immediately and then proceed to uninstall it.
01:37For both Android and iOS users, pay close attention to app permissions. Your flashlight app doesn't need
01:43access to your contacts, and a calculator doesn't need to use your microphone. Go into your settings and
01:48review the permissions for each app. Be ruthless. If an app is asking for permissions that don't make
01:54sense for its function, revoke them. Modern operating systems make this process quite straightforward.
01:59This simple step can prevent a legitimate but overly intrusive app from harvesting your data,
02:04and it can stop a malicious app in its tracks. Now let's move on to your computer. Whether it's a
02:10Windows PC or a Mac, the principles are similar. Start by checking your installed programs.
02:16On Windows, go to Apps and Features, and on Mac, check your Applications folder. If you find software
02:22you didn't intentionally install, get rid of it. Be careful, as some system-critical files might have
02:28unfamiliar names. When in doubt, search the program name online before deleting. Also, check your browser
02:34extensions. Malicious extensions are a common way for spyware to get onto your system. They can monitor
02:40your browsing, steal passwords, and inject ads. Go through your browser as extensions or add-ons menu,
02:46and remove anything you don't recognize or no longer use. A crucial step for any computer audit
02:52is to run a thorough scan with reputable anti-malware software. Don't just rely on the quick scan. A full,
02:58deep-system scan is what you need. There are many excellent free and paid options out there,
03:03like Malwarebytes, Bitdefender, or Norton. Make sure your security software is fully updated before you run the
03:10scan, so it has the latest definitions to detect new threats. It's also a good idea to get a second
03:16opinion. You can run a scan with your primary antivirus and then use a different on-demand scanner
03:21to see if it catches anything the first one missed. Let's dig a bit deeper into network activity.
03:27This is a more advanced technique, but incredibly effective. You can use tools to monitor your device's
03:32network traffic on a computer. Software like Wireshark or GlassWire for Windows and Little Snitch
03:38for Mac can show you exactly which applications are connecting to the internet and where they
03:43race sending data. You're looking for strange connections to unknown servers, especially if
03:48they're happening when you're not actively using an application. If you see an app sending a constant
03:52stream of data to a weird IP address, that's a huge red flag. This can be complex, but even a
03:59basic
03:59look can reveal a lot about what's happening under the hood. Another critical area to check is your
04:04system startup processes. Malware often configures itself to launch automatically when you turn on
04:09your device. On Windows, you can check this in the Task Manager under the Startup tab. On a Mac,
04:15you can find it under Login Items in your User Settings. Disable any unfamiliar or suspicious
04:21programs from starting automatically. This won't remove the malware, but it will prevent it from
04:26running, making it easier to find and delete. While you're there, look at the running processes or
04:31activity monitor. If you see a process with a bizarre name or one that has using an unusually
04:36high amount of CPU or memory, investigate it. A quick search can tell you if it's a legitimate
04:42system process or something malicious. Now, let's talk about rooting and jailbreaking. If your Android
04:48device is rooted or your iPhone is jailbroken, it's significantly more vulnerable to attack.
04:53These processes remove the built-in security protections of the operating system. Well, it allows.
04:58For more customization, it also opens the door for malware to gain deep system access.
05:04If you suspect you have a persistent infection and your device is rooted or jailbroken,
05:09the best course of action is often to perform a full factory reset and restore the original,
05:14unmodified operating system. This is a drastic step as it will erase all your data. So make sure to
05:20backup your important files first photos, documents, and contacts, but not the apps themselves,
05:25as you might backup the malware along with them. Speaking of factory resets, this is your nuclear
05:31option. If you've tried everything else and you still suspect your device is compromised,
05:36a factory reset is the most reliable way to ensure it's clean. It will wipe your device and
05:41return it to its out-of-the-box state. Before you do this, as I said, backup your essential,
05:47non-executable data. After the reset, be very careful about what you reinstall.
05:51Only install apps from official sources like the Google Play Store or Apple App Store and stick to
05:57well-known, reputable developers. This process ensures you're starting from a clean slate and
06:02haven't reintroduced the problem. Finally, prevention is always better than a cure.
06:07To keep your devices secure moving forward, always keep your operating system and applications updated.
06:13These updates often contain critical security patches. Use strong, unique passwords for all your
06:19accounts and enable to factor authentication wherever possible. Be skeptical of unsolicited
06:24emails and messages, especially those with links or attachments. Don't install software from untrusted
06:30sources. Regularly backing up your data is also a lifesaver. If the worst happens, you can reset your
06:36device without losing your precious memories and files. Conducting a security audit might seem daunting,
06:42but taking these steps can give you peace of mind and control over your digital life.
06:46Stay vigilant, stay informed, and you'll be much safer online.
