How To Tell If My Computer Has Been Hacked – Cybersecurity has become a major threat over the years, but it has also become easier to identify and avoid. But that’s assuming you know the signs and the right steps to prevent and combat cyber security attacks.
But the obvious question in your mind is how to know if your computer has been hacked? A computer that has been cyberattacked, or otherwise hacked, will behave in certain ways, often in mysterious ways. More often than not, you’ll be able to tell when something isn’t right. Here’s how to tell if your computer has been hacked.
How To Tell If My Computer Has Been Hacked
We use the word “hacked” more broadly to describe a compromised system or account. Hacking usually means that the hacker is in control of planning every move, but many hacks, such as viruses and malware, do not require active control. So for the purposes of this guide, we’ll cover situations where computers are compromised, from actual hacking to different types of malware.

An infected computer often behaves erratically. You may notice several signs that your computer may be infected. Here are the most common ones.
There are a few common attacks to watch out for. If your computer has been hacked, one of them may be the cause.
A Denial of Service (DoS) attack is exactly what it sounds like. An attack designed to prevent the intended user(s) from accessing a system or service. This often involves unauthorized password changes and will lock you out of your computer or accounts. It can also come with a ransomware attack where the hacker holds your system and data for ransom and asks you to pay money to get it back.
A Trojan horse attack is when a malicious program pretends to be a good program. It is able to bypass your operating system and anti-virus security measures by pretending to be a legitimate program and continue to attack your system from the inside. Ransomware attacks are also often followed by Trojan horse attacks.

A phishing scam is when a criminal tries to direct you to a fake website, usually a social network or bank account, to trick you into entering your login details. The hacker then gains access to your sensitive information and puts your information and finances at risk. Be careful as criminals and crooks often do this over the phone and pretend to be customer service agents.
These are more common but can be just as dangerous. Hackers design and mass release these viruses and malware to steal data and disable your system. More sophisticated ones can give away too much of your information to hackers or let them take over your system.
Prevention is better than cure and in this case it is even more so. Stopping hacks on your computer starts with vigilance. Here are some steps to prevent your computer from being hacked.
