How to Get Rid of Win32/Crowti.A Ransomware from Your PC?

Hello. My computer appears to be infected with the Win32/Crowti virus and possibly other variations of it. Malwarebytes picked up nothing during a scan. Microsoft Security Essentials (MSE) removed it but on an infrequent basis it comes back and MSE will quarantine it prior to me removing it. Files on my computers desktop were corrupted (i.e. word, excel, PDF, etc.) and I have them saved in a single folder which I plan to discard. I also found 855 instances of Decrypt.txt and Decrypt.png files on my hard drive that I deleted. Computer seems to be running okay but I am not sold that the virus/malware is removed. Your help would be greatly appreciated. Thanks.
