Hello all , I have WInXp pro , and I get this messgae when I try to open some problematic EXE file : "windows cannot access the specified device path or file " Why problematic? Because AVG has detected it as Trojan horse. Although I have to use this file and succeded to open it on other computer with WinXP. I am planning to use this file only when I need to and then delete it. What can I do? :blush: I logged in as Administrator but no nothing.
