Not sure if this link will work for you Hessah but uhh I use panda antivirus and its pretty good...(better be it cost me $70). They have this online scan that detects like everything that you might have. So pretty much anything that goes through my antivirus will be found in the online scan thinger...So could give this scan a shot.
