Hi everyone!! I am a Windows XP Home user, until a week ago when I bought a laptop PC with Vista Home Premium (CPU Core 2 2.2GHz and 2MB RAM). I installed EAV 3 onto my new PC and when I tried to scan, I get the following messages: C:\.................. - decompression could not complete (possible reasons: insufficient free memory or disk space, or a problem with temp folders) In addition, the scan takes too long to finish and EAV scans about 95000 files. I tried to scan with Kaspersky (real time protection disabled) with no such problems and KAV scanned 270000. http://www.imageshack.gr/view.php?file=agb4b5wce9tnh7a03jd8.jpg When I turned UAC off, everything was fine (the EAV scan is quicker with 270000 as well). Does anyone have any similar problems? Can you tell me how I can "bypass" UAC without turning it off?
