I had a malware hack (trojan virus) that put my site on Google's blacklist. I was unable to remove all of the infected files and turned to OSE Antivirus for the solution. The virus infected the OSE installation, but the OSE support people were QUICK and PROFESSIONAL and not only got the product working, but cleaned all of my files. They gave some recommendations to improve site security as well. Now the site is clean and secure and the OSE Antivirus is working properly.
