Explanation
Malware can cause slow performance and generate intrusive advertisements or pop-ups.
The most likely cause of a device running slowly and displaying unexpected pop-ups is a malware infection.
Malware is malicious software designed to disrupt, damage, or gain unauthorized access to a device or network. Common types include viruses, adware, spyware, and ransomware.
- Performance Impact: Malware often consumes significant CPU and memory resources, leading to sluggish system performance, frequent crashes, and slow response times. It can also run multiple background processes that interfere with normal operations and reduce productivity.
- Pop-Ups and Ads: Adware and other forms of malware can generate excessive pop-up ads or redirect your browser to unwanted websites, even when you are not actively browsing. These pop-ups are a hallmark of infection and can further expose the device to additional threats.
- Other Symptoms: Additional signs of malware include changes in browser settings, sudden loss of storage space, and unauthorized access to personal information.
- Remediation: To address these symptoms, run a reputable antivirus or anti-malware scan, remove suspicious programs, and keep your operating system and security software updated.
Malware can slow down device performance and generate intrusive pop-ups by consuming system resources and displaying unwanted advertisements.
