You can check for recently installed suspicious or unknown extensions.


Do a malware check with several malware scanning programs on the Windows computer. Please scan with all programs because each program detects different malware. All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.

It's also worth a visit to the Windows Control Panel, Uninstall a Program. After the list loads, click the "Installed on" column heading to group the items by date. This can help surface undisclosed bundle items that snuck in with some software you agreed to install. Take out as much trash as possible here.
