Hi, about 2 months ago I tried F-Secure CS v7.12 and I didn't like it so I uninstalled the product. Unfortunately, my new antivirus (Twister) is having some compability issues and I found out through the installer of NOD32 that F-Secure still remains on my PC. I've tried many different ways (deleting keys, program directory and F-Secure's removal tool) but it just won't get away. Can somebody help me? TIA!
