how to know your pc is hacked 8 Signs
Your computer could be hacked, and you may not even know it. Hackers can take over your personal information, invade your privacy, and even steal money from your bank account or credit card details. In this blog post, you’ll learn how to spot the signs of a hack and how to protect yourself from becoming a victim of cybercrime.
1. Your computer starts acting up
Your computer starts acting up or you see a lot of pop-ups that you don't remember installing. You're seeing odd connections with networks or websites you have never visited. Your hard drive has taken on a sluggish feel and takes longer than usual to load programs. You hear beeping noises when you aren't even sure what the noise is from. Your virus software isn't blocking anything, but all the sudden more spyware pops up on your PC that the software couldn't seem to delete before. There are gaps in your Web browsing history that you didn't create. There are files missing or corrupted on your system drive and something seems off about how long it's taking for these things to happen. These are signs that your PC may have been compromised by a hacker and there could be sensitive information at risk.
2. You get pop-ups, errors, and warnings
When you see pop-ups, errors, and warnings in an email, web browser, or any of the other apps on your computer that mention ransomware (or with ransom note text), then you probably have an infection. This could mean that someone has been hacking into your computer without you knowing it. These messages are also often sent as attachments in emails asking for personal information or asking for you to open a document or a link. Ransomware comes in two types: crypto and crypto-repair. Crypto-ransomware encrypts all of your files so they can't be opened by anyone but the hacker who encrypted them. It's impossible to recover files from these types of infections without paying the fee demanded by the hacker. Crypto-repair ransomware just locks down your computer until you pay up.
3. Program settings are changed
Program settings are changed when you download a virus, or any other type of malware, on your computer. You may not see the changes until it's too late. You will probably see a pop-up notification, but the most obvious change is that the website shortcuts on your desktop have changed. For example, they may now lead to advertisements and websites unrelated to what you've been browsing. Your browser search bar has also been taken over with sponsored links.
The usual solution for this problem is to use anti-malware software like antivirus programs, firewalls, and spyware removal tools. The easiest way to remove the malicious files is by rebooting your PC in safe mode with networking. Then scan for viruses and remove them all at once.
4. Programs you didn’t install start showing up in Programs and Features
If you are getting pop-ups that won't go away and new programs suddenly appearing in your Programs and Features list, then you may be infected with malware. Malware can take over your computer and make it hard for you to delete those programs from the Programs and Features list.
You will need a program called CCleaner, which is free for home use. Click the Registry tab on the left side of CCleaner. Click the Browser Helper Objects tab on the right side of CCleaner. Click on each of these browser helper objects one by one and hit Delete at bottom of window for each one. Repeat process again until all objects have been deleted.
5. Suddenly you can't connect to Wi-Fi anymore
It's not uncommon for Wi-Fi signals to drop every once in a while. Perhaps the router had been turned off, or there might be too many people using it. But if you're suddenly disconnected from Wi-Fi and can't reconnect, then you might have a hacked computer! Cybercriminals are looking for unprotected computers that they can access remotely, so here are some signs of how you can know if your computer has been hacked If you see an ad for something on your Facebook account that you didn't buy or post yourself, then someone might have hijacked your account. If you get spam emails containing links, attachments, or messages asking for personal information (such as credit card numbers), then this could also mean that someone hacked into your account. You should always change passwords regularly on all accounts where it was used and try to avoid using the same password across different accounts.
6. You’re Receiving Spam E-Mail
7. Files go missing from Documents, Pictures, Music, etc.
One way hackers can get your information is by hijacking files on your computer. One of the ways they do this is by changing the extension. For example, a hacker may change a .docx file to a .zip file so that you'll download it and extract whatever's inside, which is often malware. Another way hackers hijack files is by touching them— meaning, copying or modifying data in such a way that even careful users won't notice anything amiss. So if you find an unfamiliar file among yours, don't open it. Instead, check to see if there are any changes in the modified date/time and size. If there are, delete the file immediately without opening it!
8. Strange New Services Running on Startup
Check for new, unfamiliar services that are set to automatically start up when you log in. If you find one that you don't remember installing or adding yourself, search the internet for the name of the file, and see if there are any reports of it being malicious. To stop a service from running on startup, open Task Manager by pressing Ctrl+Shift+Esc and then go to Services tab. Find the service with an unknown name, right-click on it and select Properties. Go to General tab and uncheck Startup type: Automatic. You can also disable this service from running by going back to Services tab and clicking on Stop at the top of the window.
