My wife has Sony Vaio laptop that originally came with Windows 8 and has been upgraded to Windows 10. She works remotely from home and her company IT guy mistakenly installed company firewall and antivirus software on her personal laptop because she had not been issued a company laptop yet. She finally got him to uninstall them, but now it's acting flakey. The Windows mail app and others won't open now. She wants to just wipe it and start over.
