You may find that your files (such as office documents or photos) are no longer available; You can’t open them and their icon and extension have changed. This is a sign that the hacker has encrypted your files and will likely demand a ransom to get your files back.
How To Tell If My Computer Has Been Hacked
Tip: Never pay ransom to hackers! The best solution against ransomware is to back up all your files daily or weekly to an external drive or the cloud.
After taking over an email account, the threat actor almost always uses that account to spread spam and viruses. If your friends, family, or coworkers receive promotional emails from you, your email may have been compromised. Log in to your email account and change your account password.
Tip: You can spoof email addresses even without hacking into the account. After changing your email password, if your friends continue to receive emails that you didn’t send, someone is probably spoofing your email address.

Installing a bandwidth monitor on your computer can help determine which programs are using your computer’s bandwidth. Windows users can also use the “netstat” command to determine remotely established network connections and open ports. However, there are several legitimate reasons why your internet connection may be slow, such as other users at home or in the office, downloading large files, or website maintenance, among others.
Computer security programs and firewalls help limit access for security purposes. If your computer is asking you to access programs you don’t recognize, rogue software may have been installed or hacked. If you don’t know why a program needs Internet access, we recommend blocking access to that program. If you later find that these blocks are causing problems, you can remove them.
Tip: A firewall asking you for access could also be someone trying to probe your network, looking for open or available ports.
If your computer’s antivirus, anti-malware, or firewall has been removed or disabled, this may also indicate a compromised computer. A hacker can disable these programs to hide any notifications that appear while they are on your computer.

If your computer is deeply exploited, it’s possible for a malicious third party to remotely control your computer, running all the programs you have permission to run. If they manage your current login session, they can even control your computer as if they were sitting at your desk, using your keyboard and mouse. For example, the mouse cursor may move or something may be typed.
Another example is that you can see that the computer’s camera light is working without turning it on. If you see your computer acting as if someone else is in control, it could be an indication that your system has been exploited at a basic level.
If you notice that your web browser configuration has suddenly changed, it could be a symptom of a virus or malware infection. Examples of sudden browser changes include changing your home page, adding a third-party toolbar, or changing your default browser to something you don’t want.

Users are often advised to use antivirus to check if their systems are infected, but in the current cybercrime scenario, this is simply not enough. It often takes at least a basic understanding of security issues to determine if a computer is infected, and many first-time users have little or no idea. Although many of today’s threats are specifically designed to remain undetected, there are still some telltale signs that a system has been compromised.
PandaLabs, Panda Security’s anti-malware lab, has created a simple guide to the 10 most common infection symptoms to help all users know if their systems are compromised:

In all of the above scenarios, and if you have even the slightest suspicion that you are infected, PandaLabs recommends that you look for alternative security applications to the ones you have installed (if you have any). You don’t need to uninstall them, you can just use a free computer sanitizing tool like Panda Cloud Cleaner or install an antivirus that is compatible with other machines, like Panda Antivirus, which is also free.
One thing’s for sure, getting a second opinion on your computer’s health can save your data, your privacy, and in many cases, your money.
Panda Security specializes in the development of endpoint security products and is part of the WatchGuard portfolio of IT security solutions. Originally focused on the development of antivirus software, the company has since expanded into advanced cyber security services with cyber crime prevention technology. In this day and age, online crimes are becoming significantly real, and we should all be concerned about the safety and security that new technology presents. Earlier, you had to be an expert to hack into computers, but now anyone can do it. The report says that 60% of computers have been hacked in one way or another. It can be difficult to tell if you are one of them, so we decided to share some useful facts that can help you determine if your privacy is at risk.
First and foremost, go directly to the computer settings and check the status of your antivirus software. If your antivirus is running and doing what it was supposed to do in the first place, then things are normal. This is a direct red flag, that your computer is compromised, when your antivirus status is detected or “disabled” and you never did it yourself. It certainly does not happen by itself, unless some external force acted on it.
How Can I Know If My Computer Is Infected?
This is usually the first thing hackers do to gain access to your computer. This will allow them to easily navigate your computer into your valuable information.
One of the ways a hacker will try to get their hands on you is by sending fake virus alerts that say “your computer has been hacked, click here to fix”. Some even have verbal comments.
The job of your antivirus is to prevent someone from accessing your computer directly, which means that if they want to access your information, it will be at your request. Fake virus alerts are one of the most common ways people fall victim to an attack because they click on a message when it’s in question. But instead of being helpful, it ends up giving the hacker access to your computer. It’s like opening the door to a burglar and handing him your keys and saying “I now give you permission to access anything whenever you want.” So, ignore the warnings and don’t download these fake antivirus software.
We may have noticed that toolbars or favorite web browsers are randomly changed or deleted by software updates; It’s frustrating if you can’t uncheck the box to disallow this and get a whole new toolbar to replace the existing toolbar. If this is happening on a larger scale, you may need to do some investigating.
What To Do If Your Computer Has Been Hacked? How To Fix It?
Normally, when you install the software, the web browser is reset to its defaults. If this happens without your knowledge or something has been added to the toolbar or favorites, immediately take your computer to a professional who can better solve these problems. If things are added or removed without you physically doing so, then there must be malware on your computer. A hacker is out there, and you are vulnerable to losing your precious data sooner or later.
Never enter passwords or login to your NetBank if these toolbars appear.
