Hello, I have finished my trial period and have now purchased a permanent license. I'm impressed with this program, but have some questions which perhaps someone here can answer. 1. During trial period I did a full system scan almost every day with all options checked. The results were the same for almost three weeks: completely clean. But then 11 hidden ADS showed up all at once. The help file doesn't really explain the origin of these. Where do they come from? Why a clean system for many weeks and then all of a sudden, many show up? EIght small(88 bytes), but 3 were over a thousand bytes. I deleted all. and haven't seen any ADS show up for last week. 2. After adding the key file to the TDS directory, I am seeing programs asking to run that have never ran before. Proc Guard permission request screen show that grpconv.exe and runonce.exe are asking to run. Filealyzer shows that these programs have never run before on this machine(which is over 6 months old). Are they safe to allow? Thanks for your help.
