Is httpproxy.exe safe or a potential security risk? or What exactly does httpproxy.exe do on my syste

Not all httpproxy.exe processes are bad. Some apps like CCleaner or certain antiviruses use it for network stuff.

But if you’re unsure:
1. Check the digital signature (right-click file > Properties > Digital Signatures).
2. No signature? Sus.
3. Run a full scan with Windows Defender + SuperAntiSpyware.
