Which of the following is a common method that computer viruses use to propagate?
Which of the following is a common method that computer viruses use to propagate?
निम्नलिखित में से कौन-सी वह सामान्य विधि है जिसका उपयोग कंप्यूटर वायरस प्रसार के लिए करते हैं?
Detailed Solution & Logic
System updates/ सिस्टम अपडेट
✅ Explanation
- Virus propagation refers to the ways in which a virus spreads across computers or networks.
- Common ways viruses spread include:
- Infected software updates / System updates – If updates are downloaded from untrusted sources, viruses can attach themselves.
- Email attachments / Downloads – Clicking on infected files can spread viruses.
- Removable media (USB drives, external hard drives) – Viruses can copy themselves to connected devices.
Other options explained:
- Hardware upgrades → Not a usual way for virus propagation.
- Software licensing → Does not inherently spread viruses unless pirated software contains malware.
So, the correct answer is:
C) System updates / सिस्टम अपडेट
✅ व्याख्या
कंप्यूटर वायरस ऐसे दुर्भावनापूर्ण प्रोग्राम हैं जो कंप्यूटर से कंप्यूटर में फैल सकते हैं।
सामान्य प्रसार की विधियाँ:
- सिस्टम/सॉफ्टवेयर अपडेट – यदि अपडेट स्रोत अविश्वसनीय या संक्रमित हो, तो वायरस फैल सकता है।
- ईमेल अटैचमेंट / डाउनलोड – संक्रमित फाइल खोलने पर वायरस फैलता है।
- रिमूवेबल मीडिया (USB, एक्सटर्नल ड्राइव) – कनेक्टेड डिवाइस में वायरस कॉपी हो सकता है।
अन्य विकल्प:
- हार्डवेयर अपग्रेड → वायरस फैलाने का सामान्य तरीका नहीं।
- सॉफ्टवेयर लाइसेंसिंग → यदि पायरेटेड या संक्रमित सॉफ्टवेयर हो तो खतरा हो सकता है, लेकिन सामान्य तरीका नहीं।
इसलिए सही उत्तर है:
C) System updates / सिस्टम अपडेट

Extra Facts / अतिरिक्त जानकारी
Viruses often spread through phishing emails, freeware/shareware downloads, and updates from untrusted websites.
वायरस अक्सर फिशिंग ईमेल, फ्रीवेयर/शेयरवेयर डाउनलोड और अविश्वसनीय वेबसाइट्स से किए गए अपडेट के माध्यम से फैलते हैं।
Security measures / सुरक्षा उपाय:
Always update your system from official sources only.
हमेशा अपने सिस्टम को केवल आधिकारिक स्रोतों से ही अपडेट करें।
Keep your antivirus software updated.
अपने एंटीवायरस सॉफ़्टवेयर को अपडेट रखें।
Do not download suspicious files.
संदिग्ध फाइलें डाउनलोड न करें।
