Jautājums

SuperUser lasītājs Džons Sondersons vēlas uzzināt, vai Windows 7 atjaunināšana ir pietiekama, lai saglabātu drošību vai arī viņam būtu jāinstalē arī pretvīrusu programmatūra:

I was thinking, given that I keep Windows 7 regularly updated through Windows Update, does this make having anti-virus software installed a useless gesture? I may well be a naive user, but it seems to me that if security concerns are found, then any patches to the operating system to close those security holes should solve the problem.

So, if my Windows 7 system is up to date via Windows Update, and I do not use an administrator account (but a restricted account instead), do I still need anti-virus software?

Vai Windows 7 sistēmas atjaunināšana ir pietiekama, lai saglabātu sistēmas drošību, vai arī jāinstalē pretvīrusu programmatūra?

Atbilde

SuperUser atbalstītāji Scott Chamberlain un Frank Thomas ir atbilde mums. Pirmkārt, Scott Chamberlain:

Updates to Windows will not protect you from software that you yourself have run. If you are tricked into running a malicious program, it can unleash its payload.

You also state, “…if I keep myself logged in as a regular user without administrative privileges” but get a UAC prompt from a program and type in the administrator credentials, it does not matter that you are a regular user.

Windows Update does not protect you from bugs in other software like your web browser (unless you are using Internet Explorer), so a virus could get in that way (which anti-virus software would have blocked).

Lastly, even if the program never gets administrative privileges and does not use any exploits in Windows, there are still plenty of bad things it can do within the bounds of a restricted user account. A non-elevated program can read almost all the files on your hard-drive and send that information anywhere it wants. If you have any valuable information on your hard-drive, the malware author now has a copy of that information as well.

Pēc Frank Tomas atbildes:

No. Windows Update often patches vulnerabilities used by worms and viruses, but rarely affects a trojan’s ability to mess you over. Additionally, lots of bad software can affect you and your user profile without administrative privileges. Back in 2010, we were removing fake anti-virus apps from systems where no admin had ever logged in.
