After System 32 windows file quarantined, am now unable to reboot XP system without using the restore CD. &nbsp;I have no expertise to extract Sys32 file from CD and install. &nbsp;Don't know where to download it on line. &nbsp;No Sasser. <br />
&nbsp; &nbsp;I'm new to this site. &nbsp;At first I did get some info on Sys32 issues, but it disappeared when I went to another window. &nbsp;I have little expertise to generalize information from sys32 issues I read to my &quot;quarantined&quot; and reported &quot;Download.Trojan&quot; as the culprit. &nbsp;I assume I got rid of it withi the Symantec quarantine. &nbsp; At the same time, my server reported &quot;intercepting&quot; W32/Netsky.y.eml ! exe. &nbsp;I'm assuming they got it.<br />

Also...how do I find my question and answer if I log out and log back in? &nbsp;Thanks.

   I'm new to this site.  At first I did get some info on Sys32 issues, but it disappeared when I went to another window.  I have little expertise to generalize information from sys32 issues I read to my "quarantined" and reported "Download.Trojan" as the culprit.  I assume I got rid of it withi the Symantec quarantine.   At the same time, my server reported "intercepting" W32/Netsky.y.eml ! exe.  I'm assuming they got it.

Operating system security (OS security) is the process of ensuring OS integrity, confidentiality and availability. OS security refers to specified steps or measures used to protect the OS from threats, viruses, worms, malware or remote hacker intrusions. OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised, including authentication, passwords and threats to systems and programs.
