What to Do After Virus Removal?

• Email accounts
• Social media (Facebook, Instagram, VK)
• Online banking
• Important services (PayPal, Amazon, etc.)

2. Enable Built-in Protection

Make sure Microsoft Defender is active and working:

1. Open "Windows Security" (shield icon in tray)
2. Go to "Virus & threat protection"
3. Make sure real-time protection is enabled
4. Enable "Cloud-delivered protection" for better detection

Many viruses exploit vulnerabilities in outdated Windows versions. Check for updates:

1. Open Settings → Update & Security
2. Click "Check for updates"
3. Install all available updates

Preventing Future Infections

To avoid re-infection, follow digital hygiene rules:

• Download software only from official websites — no "activators" or "cracks"
• Don't open suspicious emails — especially with attachments from strangers
• Keep Windows and programs updated — most viruses exploit old vulnerabilities
• Use strong passwords — different for each website
• Make backups — to external drive or cloud
• Check website addresses — scammers often fake popular services
• Don't use questionable extensions — install only verified ones
