Malware Alert: 10 Warning Signs Your Computer Could Already Be Compromised

Malware can find its way onto a computer through suspicious links, infected downloads, fake software updates or malicious email attachments. According to cybersecurity experts, many users do not realise their devices have been compromised until noticeable performance issues or unusual behaviour begin to appear. While some symptoms may have harmless explanations, a combination of warning signs should never be ignored. Identifying a possible malware infection early can help limit damage, protect sensitive information and reduce the chances of data loss or identity theft.

1. Your Computer Has Become Unusually Slow

A sudden drop in performance without any obvious reason could indicate malicious software running in the background and consuming system resources.

2. Frequent Pop-Up Advertisements

If unwanted adverts appear constantly, even when your browser is closed or you're not visiting suspicious websites, adware or another form of malware may be responsible.

3. Programmes Crash Unexpectedly

Applications that repeatedly freeze or close without warning may point to system instability. According to experts, malware can interfere with normal software operations.

4. Your Browser Keeps Redirecting

Being redirected to unfamiliar websites or finding that your homepage or search engine has changed without permission is a common warning sign.
