1) Quick answer (TL;DR)
Avast is most likely showing a false positive when you visit TZLA.club.
- The site does not run malware.
- The site does not run crypto-mining scripts.
- Avast can flag some JavaScript or page content (including crypto-related content) using heuristic detection.
- You can confirm safety and keep browsing by using a different browser, adjusting Avast settings, or verifying the site in a separate scanner.
2) Who this is for / When to use this article
Use this article if:
- You see an Avast warning (virus, malware, or “threat blocked”) when visiting https://tzla.club.
- You are browsing with Firefox and have uBlock Origin and Avast enabled.
- You are worried the site is running crypto mining in your browser.
- You are trying to read the site or complete a membership donation and the warning blocks access.
3) Important notes
- We do not ask members to disable security tools permanently. If you choose to change antivirus settings, do it carefully and reverse it if you are unsure.
- If you believe your device is infected, stop and contact a qualified IT professional. If you want help from the TZLA group, share only non-sensitive screenshots.
4) Definitions
- False positive: A security tool reports a threat when there is no real threat. Why it matters: It can block safe sites and create unnecessary concern.
- Heuristic detection: A “behavior and pattern” scan that makes an educated guess. Why it matters: It can flag normal website code if it resembles known threat patterns.
- Browser-based crypto mining: JavaScript that uses your device’s CPU to mine cryptocurrency. Why it matters: It can slow your device and is often unwanted.
- uBlock Origin: A browser extension that blocks ads and scripts. Why it matters: It can change how a site loads and occasionally interacts with security scans.
- Exception / Allowlist: A rule that tells antivirus to allow a site. Why it matters: It can remove warnings, but should only be used when you are confident.
- URL check: Confirming you are on the correct domain (tzla.club). Why it matters: Lookalike domains are a common source of real risk.
5) Step-by-step instructions
1) Confirm you are on the correct TZLA URL
- What to do: In your browser address bar, verify the domain is exactly tzla.club (or https://tzla.club).
- What “good” looks like: The address bar shows tzla.club. No extra words, dashes, or unusual subdomains.
- Common mistake to avoid: Clicking a link to a lookalike domain (for example, misspellings).
2) Capture the Avast warning details
- What to do: Take a screenshot of the warning and note the exact detection name (for example, “URL:Mal”, “JS:…”, or similar) and the page URL.
- What “good” looks like: You have the detection label and the exact URL that was blocked.
- Common mistake to avoid: Sharing private information (full name, email, device identifiers) in screenshots.
3) Try a clean comparison test (same device)
- What to do: Open the same page in a private window and temporarily disable only one variable at a time:
- Test A: Firefox + uBlock Origin ON + Avast ON (current state)
- Test B: Firefox + uBlock Origin OFF + Avast ON
- Test C: Another browser (Chrome, Brave, or Edge) + Avast ON
- What “good” looks like: You identify which combination triggers the warning most reliably.
- Common mistake to avoid: Turning off multiple protections at once, then not knowing what changed.
4) Confirm the site is not doing browser mining (sanity check)
- What to do: When the page is open, check your device activity monitor:
- Windows: Task Manager
- macOS: Activity Monitor
- Linux: System Monitor
- Look for unusual sustained CPU usage by the browser tab when the page is idle.
- What “good” looks like: CPU usage returns to normal after the page finishes loading.
- Common mistake to avoid: Confusing normal short spikes during page load with mining.
5) Choose the safest next action for continued access
- What to do: Use one of these options:
- Use a different browser that does not trigger the warning.
- Keep Avast enabled and do not add an exception, then access TZLA content from a device where the warning does not occur.
- Once you are confident it is a false positive, add a temporary exception for tzla.club in Avast and re-test.
- What “good” looks like: You can browse TZLA.club without recurring blocks, and you still keep reasonable device security.
- Common mistake to avoid: Permanently allowlisting broad categories or disabling web protection long-term.
6) Escalate if the warning persists (recommended)
- What to do: Report the detection to Avast as a likely false positive and share the details with TZLA support channels.
- What “good” looks like: You have a record of the detection name, the URL, and the steps you tried.
- Common mistake to avoid: Reporting without the exact detection name and URL, which slows resolution.
6) Decision tree / Variations
- If you are using Firefox + uBlock Origin + Avast: Try disabling uBlock Origin for tzla.club and re-test. If the warning disappears, keep uBlock enabled globally and only adjust for tzla.club.
- If the warning appears only on one specific page: That page likely contains text or scripts Avast’s heuristics dislike. Use another browser.
- If the warning appears across multiple devices on your network: Treat it as higher risk. Pause and run a separate scan. Confirm you are using the correct domain. Do not add exceptions until you are confident.
- If you are concerned about membership donations or accessing member-only areas: Use a different browser/device first. That is the lowest-risk workaround.
7) Troubleshooting
- Symptom: “Threat blocked” appears only in Firefox
- Likely cause: Firefox-specific web shield behavior or extension interactions
- What to do next: Test another browser. Then test Firefox with uBlock disabled for tzla.club.
- Symptom: Warning appears only when uBlock Origin is enabled
- Likely cause: Content is loading differently and triggering heuristics
- What to do next: Add a site-level exception in uBlock for tzla.club (do not disable uBlock globally).
- Symptom: Warning appears on multiple pages of tzla.club
- Likely cause: Broad heuristic pattern match
- What to do next: Collect detection name + URLs and report as false positive to Avast.
- Symptom: Browser CPU is unusually high and stays high
- Likely cause: Heavy page content, a runaway script, or unrelated browser issue
- What to do next: Close the tab. Update the browser. Re-test. If it repeats, scan the device.
- Symptom: Warning appears only on one device
- Likely cause: Local Avast configuration, browser profile, or cached content
- What to do next: Clear cache, update Avast definitions, re-test. Consider a fresh browser profile.
8) FAQ
Q1: Is TZLA.club actually mining cryptocurrency in my browser?
No. TZLA.club does not run crypto-mining scripts. The Avast warning is most consistent with a false positive heuristic detection.
Q2: Why would Avast flag TZLA-related pages at all?
Some antivirus tools use heuristics that can over-flag JavaScript patterns or content that mentions crypto topics.
Q3: Should I disable Avast to use the site?
No. Do not disable protection as your first choice. Use a different browser/device first. If you change settings, keep it temporary and specific.
