used for a long time, great tool alongside avast, dont know where this "many" popups come from, ive never had ONE on my laptop, however when i put it on my mums computer when cleaning it popped up few times for LEGITIMATE reasons and was blocking actual malware, and thankfully it saved got rid of a keylogger, the result was similar to what that guy said about tfimon except this time it was real.
i recommend it fully, has handy rootkit scanner and process viewer and other stuff.
to be honest i forget its there unless i see it in task manager
