A pesky antivirus alert!
First, let's break down what you've told us:
1. You have Avast antivirus in the free version.
2. The antivirus keeps informing you that it has blocked access to the site `cf-apsg-perf.xinheyi.net` without you doing anything or any programs being open.
3. The threat type is listed as Malware.
4. You've run a full scan, and nothing was found on your computer.
5. You use FormatFactory (a software that uses the `net_updater64.exe` process) regularly and have added it as an exception in Avast, so it shouldn't trigger any alerts.
6. Despite this, Avast still reports the threat, and you have another computer with the same software installed.
Here are some potential reasons for this issue:
1. **False Positive**: It's possible that the `cf-apsg-perf.xinheyi.net` site is a legitimate website that's not actually malicious, but Avast has flagged it incorrectly.
2. **Software Conflict**: The `net_updater64.exe` process might be causing the issue. Since you've added FormatFactory as an exception in Avast, it should be excluded from scanning. However, there might be another issue with the process or a dependency that's causing the false alarm.
3. **Outdated Avast definitions**: It's possible that Avast's virus definitions are outdated, which could lead to incorrect flagging of legitimate sites.
To troubleshoot this issue, I recommend the following steps:
1. **Check Avast definitions**: Make sure your Avast antivirus is up-to-date with the latest virus definitions. You can do this by opening Avast, clicking on "Menu" (three horizontal lines) > "Settings" > "Update" and checking for updates.
2. **Re-add FormatFactory exception**: Double-check that you've added FormatFactory as an exception in Avast correctly. Go to "Menu" > "Settings" > "Exceptions" and make sure FormatFactory is listed as an exception.
3. **Check for conflicts with other software**: Temporarily disable any other software that uses similar processes or components to FormatFactory to see if the issue persists.
4. **Report the issue to Avast**: If none of the above steps resolve the issue, you can report it to Avast's support team or their virus and worm section (where you originally posted). Provide them with more details about your situation, including any error messages or logs.
