Scanning is very simple, just select the Scan Your Computer button then select the drives and type of scan you would like to perform. Your first scan should be the Quick Scan because if you are attempting to get your computer back from the infections you will still need to run other malware / AV / Spyware complete scans at another time all at the same time, but for now we are working on just getting control. After the scan is complete you will need to tell SuperAntiSpyware to remove the infections.
