I've been using Enigmasoft - Spyhunter for more than five years. I have compared other malware removal tools, on various Computers and operating systems over that period. I found that Spyhunter has a broader range of elimination; yes, the process can be slow and a second clean-up is needed "with some trojans" but it does the job & saves the PC,,, I've stayed with Enigma because it is the real deal.
On a number of occasions, their Help-desk advised on the removal of tricky malware that needed special attention. As to value for performance; it's money well spent.!
