F-secure fails to run
I installed F-secure via Virgin Media about 4 months ago. Up till now it has run perfectly, but today it is not running and will not open. The only things that have changed since yesterday (when it was working fine) is that I have installed Adobe Photoshop Elements 12 and Premier elements 12. I am using a PC with Windows 7 Service Pack 2. (I did not switch F-Secure off before installing the Adobe software). Suggestions welcome!
