Unless you specifically installed Net Support, Client32.exe is likely on your computer due to malware. If this is the case, please upload and share logs from Farbar Recovery Scan Tool (FRST).
https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/
- Run FRST and press Scan.
- Two logs are created in the folder that FRST is run from, FRST.txt and Addition.txt.
- Upload the logs to OneDrive, Google Drive or any file sharing service.
- Post the share link.
Note: If you are downloading FRST with Edge, smartscreen will initially block it.
Click on the 3 dots next to the warning and select Keep-> Show more-> Keep anyway.
I would also recommend you disconnect that computer from the internet until the malware is removed.
