Hello, I have carefully read your requirements, and it will be an honor to work with you on cleaning and securing your OpenCart store. With 14 years of experience in PHP, OpenCart, malware removal, and hacked website recovery, I have successfully resolved redirect malware, injected scripts, hidden backdoors, and reinfection issues on ecommerce websites.

I will remove all malware and backdoors, eliminate reinfection mechanisms, harden vulnerable areas, and thoroughly test the storefront, product pages, cart functionality, and PayPal checkout flow to ensure stability. A detailed report will be provided outlining the root cause, files affected, actions taken, and security recommendations until your planned Shopify migration. Please check my profile to review ratings, feedback, and similar malware cleanup and website recovery projects I have successfully completed.

Hi there, I can see this isn’t a random redirect issue , it’s likely a reinfection path hiding in OpenCart’s cart flow, core files, or writable assets. I’ve handled PHP/OpenCart cleanup work before, including tracing obfuscated injections, backdoors, and server-side reinfection points without touching orders or customer data. My first steps would be: take a backup, compare core OpenCart files, inspect catalog/startup/theme/JS/.htaccess/configs, review cron and logs, then trace the cart/add-to-cart path where the malicious redirects are likely triggered. I’ll clean the infection, harden the weak points, and verify product, cart, and PayPal checkout behavior after remediation. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Do you want me to prioritize only cleanup and stabilization, or should I also harden the server to reduce reinfection risk? I can start as soon as you provide SSH/SFTP and admin access, and I’ll keep you updated with a short report of what was found and changed. Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

Hi there, I will identify and remove the redirect malware from your OpenCart 3.0.3.3 store — infected files, backdoors, and database injections — then verify your full checkout flow including PayPal. My first step: grep the codebase for eval/base64_decode patterns and check catalog/controller startup files, since cart-triggered redirects often hide in event handlers or modified route controllers. Questions: 1) Do you have a clean backup from before late April? 2) Is any caching layer active — Varnish, Redis, or similar? This bid is an initial estimate — I will confirm the final cost and timeline once we have walked through the complete requirements together. Send me a message and we can go over the details. Best regards, Kamran

Greetings, I see that you need urgent help with a malware issue on your OpenCart store. It sounds like visitors are being redirected to harmful pages, especially when they interact with the cart. This is definitely concerning, especially with the warnings from antivirus tools. To tackle this, my first steps would be to thoroughly check the core and startup files, as well as the .htaccess and database content. I’ll look for any hidden scripts or backdoors that might be causing these redirects. I’ll also ensure that your data remains intact and that we have backups in place before making any changes. I have experience dealing with similar malware cleanup projects, and I understand the importance of keeping your store stable during this transition to Shopify. Best regards, Saba Ehsan

Hi, We’ve successfully cleaned multiple OpenCart stores from malware, including versions 3.0.2.2 and 3.0.3.3. We’ve also developed custom modules and integrated payment gateways like PayPal and Stripe, so we’re well-versed with the platform. For your project, I’d start by checking server logs and PHP processes to identify the source of the redirection. We can also use a tool I developed to scan for malicious code in core files, custom modules, and third-party extensions. Let’s schedule a 10-minute call to discuss your project in more detail and ensure I fully understand your needs. I’m ready to start immediately and can dedicate 3–4 hours daily to this task. Looking forward to hearing from you. Best, Adil

Hi I can help clean and stabilize your infected OpenCart 3.0.3.3 store without rebuilding, upgrading, or touching business data. The main technical issue is that intermittent redirects are often caused by hidden PHP backdoors, injected JavaScript, database payloads, .htaccess rules, or server-level cron reinfection. I would first confirm a backup, then inspect OpenCart core files, catalog/theme files, writable folders, configs, database content, cron jobs, server logs, and suspicious obfuscated code like eval, base64_decode, and remote URL injections. After removing the redirect source and backdoors, I would test storefront pages, product pages, add-to-cart, cart, and PayPal checkout, then provide a short report of what was found and changed. Thanks, Hercules
