On the other side, any antivirus which analyze every single file opened will, for sure, slow down your computer a lot! Note that if you still want that kind of softwares, you could use some combined one instead of separated one which probably do not collaborate for more efficiency.
What's funny is that you really could seriously secure a Windows computer, if you take (have) the time to do it! Even without running any antivirus bloatware, the same as for GNU/Linux in fact. Do you know that? Here are the minimum tuning everybody should do in Windows: - First thing to do is to use a security-aware filesystem (which care about ownership and rights to write to the files), like NTFS (and absolutly NOT fat/vfat). Then you often still have to tune these rights properly? Meaning you should perfectly know the use of every single files in your system? sig? I can imagine the disaster if a non-technical end-user try to play with that! - Second thing to do is to use the computer with a non-admin account so even if a virus successfully enters through your account, it will not have the right to change any system file! - Third thing to do is to tune security policies correctly, for example by forbidding to run any executable outside system paths. Yes! Windows has this security option available, disabled by default, should I say "of course" ? :-( You'll notice that Microsoft leave all these options "badly" configured by default, so the system is "easy to use" for end-users, but at what a price! And of course Microsoft will propose you costly trainings and "entreprise" softwares to manage all that "easily" (once you've got your Microsoft-only certificates), but not for the home/family end-user though? All this is tuned correctly by default in a GNU/Linux system. This is one of the main reasons why GNU/Linux is far more appropriate than Windows when you need a secure environment, especially for end-users. And shouldn't everybody need one? -- Jean Christophe "????" ANDR? ? ? ?
