Hi, I just downloaded and installed ESET Smart Security Trial Version several days ago to replace NIS that came bundled with my laptop (the 90 days license period has been expired about a week ago). I have un-installed NIS prior to installing ESET Smart Security. I have updated the virus definition withour any problem, and it is still automatically updating itself until now. Yesterday I tried several times to do a scan to my entire C: drive, but the scan process never completed. It stops scanning files at different percentage of completion. Sometime it stops at 9%, some other time at 15% and the last scan stops at 8%. When the scan process stops processing more files, all other process in my computer work fine. When I pressed pause button, it show 'waiting to pause scan...' forever but there is no result. Stop button doesn't work either. I am planning to buy an ESET Smart Security license when I feel satisfied with its performance, but now I have to reconsider my plan because of this. Is this normal with the Trial Version?
