getting rid of malware on ipad air

This may come up as a question twice as i was not sure if it posted from my ipad. I seem to have acquired some malware on my ipad air. Safari and Facebook apps are often interrupted by a webpage www:smartmoneytime which on microsoft is a well known virus. I use AVG on my Microsoft products. How do I get rid of this on my ipad air? I dont know how I got it and can't find any antivirus programs to deal with it?
