Hello, I was testing NOD32 on the last skype threat, based on skype forum post http://forum.skype.com/index.php?showtopic=96634 In this topic, the dsc027.scr virus is explained and 2 links were given as redirects to download the virus. I tried to download (not execute) the virus using "save target as" just to see if NOD32 detect this threat (because I found that Mcafee Viruscan did'nt !!!) and something strange happened. The download process were aborted but no alert windows were displayed by NOD32 GUI. I repeated the same process 4 or 5 times and always the same. No alert, but download process were aborted before the file is completely downloaded. I noticed that the NOD32 icone has disappeared on the system tray (but probably NOD32 protection service was still ok). I decided to reboot the PC (note that the first test was made just after having powered on my PC and windows XP pro were completely loaded) and the second test were ok. Red windows alert as displayed each time I try to save the target file on my PC. My config : an old but still very well working PC based on abit KT7, AMD T-bird 800 MHz, 1GB SDRAM, 110 GB Hard disk, Graphic card is GEFORCE 5700 LE, Windows XP pro, Firewall is ZA pro 7 and there are no more applications running at this moment on the PC, except IE 7.0. Thank U in advance, if you have some more informations about that strange bug that only concern (a priori) the GUI functionnal entity of NOD32.
