Winupd is a dialer that uses the modem of your computer to access high-cost toll numbers that connect to pornographic websites. Winupd may be purposely installed by you, or it may be placed on your PC by accidentally visiting questionable websites. If connected, the charges will be applied to your telephone bill.
Winupd may also place spyware or malware on your computer, which tracks your online browsing habits and activities.

Malware is capable of gaining access to your personal information and can be a threat to your personal identity.
