What Is Computer Virus Removal?
Definition: Computer virus removal is the process of detecting, quarantining, and permanently deleting malicious software — including viruses, malware, ransomware, spyware, adware, and rootkits — from an infected PC or laptop, while preserving the operating system and user data.
DIY antivirus software (Windows Defender, Avast, Malwarebytes free edition) can catch surface-level infections. But sophisticated threats — rootkits hiding in the MBR, fileless malware living in RAM, ransomware that has encrypted every file — require specialist tools and offline scanning methods that free software cannot perform while Windows is running.
That is where a professional virus removal service like BAYAS becomes necessary.
How Do You Know Your Computer Has a Virus?
10 Warning Signs of a Malware Infection
| Sign | Likely Cause |
|---|---|
| PC is suddenly very slow | Cryptominer running in background |
| Browser homepage changed without permission | Browser hijacker / adware |
| Pop-up ads appear even on trusted websites | Adware / injected scripts |
| Antivirus disabled itself | Rootkit or advanced trojan |
| Folders turned into shortcuts on USB drive | Shortcut virus (most common in BD) |
| Ransom message on screen | Ransomware — do NOT pay, call BAYAS first |
| Unusual network activity at night | Botnet / RAT (Remote Access Trojan) |
| Unknown programs auto-start in Task Manager | PUP (Potentially Unwanted Program) |
| Files deleted or encrypted without your action | Ransomware or wiper malware |
| Webcam light turns on unexpectedly | RAT with spyware capabilities |
If you see two or more of these signs simultaneously, stop using the computer and call BAYAS at 01712-644590. Continued use risks spreading the infection to connected USB drives, shared folders, and network devices.
Most Common Viruses in Dhaka (2026)
Based on 800+ malware cases handled by BAYAS since 2018, these are the most frequent infections in Dhaka:
1. Shortcut Virus (Autorun/USB Malware)
The single most common infection in Bangladesh. Pen drives are shared widely in offices, print shops, and university labs — one infected drive can spread the virus to every computer it touches. The virus hides your folders and replaces them with shortcuts. Clicking the shortcut runs the malware.
BAYAS fix: Offline CMD-based unhide + removal using our bootable Linux rescue environment. Recovery rate: 98%.
2. Adware and Browser Hijackers
Installed alongside free software, cracked games, or browser extensions. Redirects your homepage, injects ads, and collects browsing data. Slows every browser session and opens security vulnerabilities.
BAYAS fix: Browser profile clean, extension audit, registry sweep. 1–2 hours.
3. Ransomware
The most dangerous category. Encrypts your documents, photos, and databases and demands cryptocurrency payment. Common variants in Bangladesh: STOP/Djvu, LockBit (targeting businesses), and localized clones.
BAYAS fix: Virus removal, decryption attempt (free decryptors available for some STOP/Djvu variants via nomoreransom.org), data recovery from shadow copies if available, system rebuild with data restoration. BDT 2,500–6,000.
4. Cryptominer (Cryptojacker)
Silently uses your CPU and GPU to mine cryptocurrency for attackers. No ransom note — just a PC that runs at 95–100% CPU constantly, overheats, and runs electricity bills up.
BAYAS fix: Process identification, removal, startup sweep. 1 hour.
5. Trojans and RATs (Remote Access Trojans)
Allows a remote attacker to access your files, webcam, microphone, and keystrokes. Often spread via cracked software, fake Adobe installers, and phishing emails.
BAYAS fix: Network connection audit, process kill, registry clean, firewall rule review.
BAYAS Virus Removal Process — Step by Step
Our 6-step process ensures the infection is fully eliminated, not just suppressed:
- Initial assessment — Review running processes, Windows Event Logs, and active network connections. 10–15 minutes.
- Data backup — Copy critical files (Documents, Desktop, Pictures) to an external drive before touching anything.
- Offline boot scan — Boot into a Linux rescue environment (Kaspersky or Bitdefender Rescue Disk) so the scanner runs before Windows loads. Malware cannot hide from an offline scan.
- Deep Windows scan — Malwarebytes Premium + Windows Defender simultaneously, targeting memory, registry, startup items, and browser extensions.
- Registry and startup clean — Manual review of all autorun locations. Every suspicious entry removed by hand.
- Hardening and verification — Enable Windows Firewall, set secure DNS (1.1.1.1), disable USB autorun, reboot, and confirm no malware processes reappear.
Total time: 2–4 hours for most home computers.

Home Service vs Workshop — Which Is Better for Virus Removal?
For most Dhaka households and small offices, home service is the better choice: your data never leaves your premises, the technician can audit your full network and router in the same visit, and you save the risk of damage during transit. Workshop drop-off suits walk-ins and phones.
BAYAS offers both. Home visits include a call-out fee (BDT 300–500, waived for jobs above BDT 2,500). Evening and weekend slots are available for home service — workshop hours are typically 10 AM to 7 PM.
Can You Remove a Virus Without Losing Your Files?
Yes — in most cases. Professional virus removal using offline scanning and selective quarantine preserves 95–98% of user files.
The exceptions:
- Ransomware encryption — Files encrypted by ransomware cannot be decrypted without the correct key. Free decryptors exist for some strains (STOP/Djvu), but not all. We always attempt decryption before recommending an OS reinstall.
- Wiper malware — Deliberately destroys files. Rare in Bangladesh consumer context but seen in targeted corporate attacks.
- DIY removal gone wrong — If a user runs multiple conflicting antivirus tools simultaneously, or attempts a manual registry edit without expertise, files can be corrupted. This is why calling a professional first is better.

How to Prevent Viruses on Your Computer in Dhaka
Virus removal fixes the current infection. Prevention stops the next one:
5 Prevention Steps for Dhaka Users
-
Disable autorun on USB drives — Open Group Policy Editor (gpedit.msc) → Computer Configuration → Administrative Templates → Windows Components → AutoPlay Policies → Turn Off AutoPlay → Enable. Stops shortcut virus spread via shared pen drives — the #1 BD attack vector.
-
Use Windows Defender + Malwarebytes Free — Built-in Defender plus Malwarebytes Free (manual weekly scan) catches over 98% of common malware. Never run two real-time antivirus programs simultaneously — they conflict and slow the PC to a crawl.
-
Never install cracked software — Cracked Adobe, Office, and games are the primary ransomware delivery vehicle in Bangladesh. Use free alternatives (LibreOffice, GIMP) or legitimate licenses.
-
Keep Windows Update enabled — Most ransomware exploits vulnerabilities patched by Microsoft within days of discovery. An unpatched Windows 10/11 machine is high-risk.
-
Back up data monthly — External hard drive + Google Drive (free 15 GB). Even if malware destroys everything, a backup makes it survivable. See our Data Recovery Service Dhaka if you need help recovering lost files.

Frequently Asked Questions
How much does virus removal cost in Dhaka?
Basic adware and browser hijacker removal costs BDT 1,200–1,800 for a home visit in Dhaka. Full malware cleaning (viruses, trojans, cryptominers) costs BDT 1,500–2,500. Ransomware cases involving encrypted files range from BDT 2,500–6,000 depending on the strain and decryption complexity. Corporate workstations are priced at BDT 2,000–4,000 per machine.
Can BAYAS come to my home for virus removal in Dhaka?
Yes. BAYAS offers home service virus removal across 36 Dhaka zones, 8 AM to 11 PM, seven days a week. A technician will come to your home or office with bootable rescue tools and a backup drive. WhatsApp 01712-644590 to book a same-day slot.
Will I lose my files when you remove the virus?
In the vast majority of cases — no. BAYAS backs up your Documents, Pictures, and Desktop before starting, then uses selective quarantine to remove malware without touching your data. The exception is ransomware that has already encrypted files before you called us. Even then, we attempt free decryption before recommending any data-destructive steps.
How long does virus removal take?
Simple adware or browser hijacker: 1–2 hours. Full malware clean: 2–3 hours. Ransomware with decryption attempt: 2–8 hours. Corporate networks: approximately one day for 5–10 workstations.
What if the virus comes back after removal?
BAYAS offers a 30-day guarantee on all virus removal work. Same infection returns within 30 days? We come back and re-clean at no charge. We also harden your system at the end of every job to reduce the risk of reinfection.
Can you remove ransomware without paying the ransom?
Sometimes — yes. Free decryptors exist for common strains like STOP/Djvu (most prevalent in Bangladesh). We check the nomoreransom.org database for your variant before any other step. If no decryptor exists, we attempt to restore files from Windows Shadow Copies (VSS). Paying the ransom is never guaranteed to work — we recommend exhausting all technical options first.
Is it safe to use the computer while waiting for a technician?
No. If you suspect ransomware, a RAT, or a cryptominer — power off and disconnect from the internet immediately. Continued use may encrypt more files, steal credentials, or spread to other devices on your home network.
Do you remove viruses from laptops as well?
Yes. BAYAS removes viruses from all laptop brands — HP, Dell, Lenovo, Asus, Acer, MSI, and Apple MacBooks. Laptop virus removal follows the same process and costs the same as desktop removal. For MacBook malware, our MacBook Repair Service Dhaka team uses macOS-specific tools.
