You cannot enable the current Gridinsoft Internet Security module on Windows XP. The operating system does not provide the supported security and network-filter environment required by the current product.
Why reinstalling will not fix it
This is an operating-system compatibility limit, not a damaged setting or license error. Reinstalling the app, changing the browser, or disabling Windows security settings cannot add the missing platform support.
Why Windows XP is unsafe for regular use
Windows XP no longer receives normal Microsoft security updates. Modern browsers and security products also no longer support it. Even if an older scanner can run, it cannot repair vulnerabilities in the operating system or provide the protection expected from a current Windows environment.
Recommended next step
- Do not use the XP computer for email, banking, purchases, passwords, or untrusted downloads.
- Back up personal documents without copying unknown executables or scripts.
- Move to a device running a supported and updated Windows version.
- Install the current Gridinsoft Anti-Malware build and update its Threat List on the supported device.
If the XP system controls irreplaceable hardware, isolate it from the internet and ask the equipment vendor or an IT professional for a supported migration plan. Contact Support if you need help transferring a Gridinsoft license to the replacement PC.
