Social engineering in security refers to the manipulation of people into performing actions or divulging confidential information, often by exploiting human emotions such as trust, fear, or urgency. Instead of attacking a computer system directly, social engineering targets the human element of security, making it one of the most effective and dangerous forms of cyberattack.
Common signs of a malware infection can vary depending on the type of malware, but many infections share similar symptoms. Here are some of the most common signs that your device may be compromised:
Performance Issues
Slow computer performance: Your computer or device may be sluggish, taking longer to start up, load applications, or perform tasks. Malware often runs in the background, consuming system resources like CPU and RAM.
Frequent crashes or freezing: Your device may freeze, crash, or display a "Blue Screen of Death" (BSOD) more often than usual.
Reduced storage space: Malware can take up a significant amount of storage space without your knowledge.
Suspicious Online Behavior
Constant pop-up ads: You may see a barrage of pop-up ads, even when you're not browsing the internet. This is a common sign of adware.
Browser redirects: Your web browser may automatically redirect you to websites you didn't intend to visit, or your search engine may be changed without your permission.
New toolbars or extensions: You might find new browser toolbars, extensions, or add-ons that you didn't install.
Unusual network activity: You may notice a sudden, unexplained spike in your internet data usage. This could be a sign that malware is communicating with external servers or sending out large amounts of data.
Unfamiliar emails or messages: Your friends or contacts might receive strange emails or social media messages from your account that you didn't send.
Unwanted Software and Files
New applications or desktop icons: You may discover new applications or desktop icons that you don't remember installing.
Missing or modified files: Files may disappear, be renamed, or be encrypted (a common sign of ransomware).
Disabled security software: Your antivirus or anti-malware software may be disabled or unable to run.
Other Red Flags
System tools are disabled: You may be unable to access system tools like Task Manager or the Control Panel.
Fake virus alerts: You may receive fake virus alerts that try to scare you into purchasing a bogus antivirus program to "fix" a non-existent problem.
Overheating or rapid battery drain: Increased resource usage from malware can cause your device to overheat and your battery to drain much faster than usual.
