PUA:Win32/Vigua.A is a type of potentially unwanted application (PUA). It's not always harmful like a virus, but it can cause issues like slowing down your system, showing unwanted ads, or installing extra software without permission. It's good that your antivirus is detecting it, but you should definitely remove it to stay on the safe side.
I recommend using a strong and reliable antivirus tool like BiteFinder Antivirus. It’s designed to detect and remove PUAs, malware, and other threats effectively. Run a full system scan and make sure your virus definitions are up to date. After removal, restart your PC and monitor it for any unusual behavior. Staying proactive is the best way to keep your system clean.
