Experiencing slow system performance, difficulty browsing the internet, or noticing unusual activity like a rapidly flashing hard drive LED could be indicators that your Windows device is compromised.
Recognizing the Signs of a Hacked Computer
While some users might receive a direct hack notification on their screen, in many cases, traditional antivirus programs may not immediately detect the issue. According to PC World, it’s essential to recognize specific symptoms that might suggest your system is under attack to take appropriate action.
Slow System Performance
One of the first signs of a potential security breach is a sudden slowdown in system performance. If programs take unusually long to start, and the CPU usage in Task Manager shows 100% despite having few applications running, this could be a red flag.
Experts note that high CPU usage can sometimes be caused by non-malicious factors, such as resource-intensive software running complex tasks. On older computers, even playing Full HD videos might push the CPU to its limits. However, a more concerning possibility is that your computer has been infected with ransomware. The encryption of large amounts of data by ransomware can significantly slow down your system as it consumes CPU resources. Similarly, crypto-jacking software, which silently uses your computer to mine cryptocurrency, can also cause sluggish performance. These malicious programs often operate through your browser, causing noticeable slowdowns.
How to Tell if Your Windows Computer is Being Hacked
To investigate, open Task Manager and look for any unfamiliar programs running in the background. If you’re unable to identify the issue, it’s advisable to run multiple thorough scans using reliable antivirus software.
Unwanted Advertisements
If you start seeing unexpected ads on your screen, it could be a sign that your device is infected with adware. Some of these ads may even mimic pop-ups that urge you to download antivirus software, which is often malware in disguise. It’s crucial to avoid interacting with these ads and refrain from downloading any suggested software.
Installation of Unfamiliar Software
In some cases, hackers can remotely control your computer to download and install unfamiliar software. They may even prevent you from uninstalling this software using traditional methods. If you find yourself in this situation, consider using specialized third-party tools designed for removing stubborn software. If the problem escalates to the point where you cannot uninstall or install new applications, restoring your computer to factory settings might be the best solution.
