Pitanje
SuperUser čitač John Sonderson želi znati je li održavanje Windows 7 ažuriran dovoljno da ostane siguran ili ako bi također trebao imati instaliran protuvirusni softver:
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?
Je li njegov sustav Windows 7 ažuriran putem programa Windows Update dovoljno da bi njegov sustav bio siguran ili je li također trebao instalirati protuvirusni softver?
Odgovor
Suradnici SuperUser-a Scott Chamberlain i Frank Thomas imaju odgovor za nas. Prvo, 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.
Slijedi odgovor Frank Toma:
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.
