O17 entries correspond to keys in registry hive HKEY LOCAL MACHINE for specific values which help windows to resolve domain names into IP addresses. Removing a needed 017 entry may break Internet connectivity since they may be used by an ISP or company network.IMPORTANT NOTE
: HijackThis only scans certain areas of a computer's system/registry
to help diagnose the presence of undetected malware in known hiding places. Given the sophistication of malware hiding techniques used by attackers in today's environment, HijackThis is limited in its ability to detect infection
and generate a report outside these known hiding places. This limitation has made its usefulness nearly obsolete
since a HijackThis log cannot reveal all the malware residing on a computer. As such, HijackThis has been replaced by other preferred tools
that provide comprehensive logs with specific details about more areas of a computer's system, files, folders and registry keys which may have been modified by malware infection.
Unless you know how to read and analyze logs from DDS, OTL or RSIT there's no point on downloading and using them. If those tools are needed for a malware infection you should seek assistance from an expert who will advise you accordingly.
Like HijackThis, these are powerful tools which rely on trained experts to interpret the log entries
, determine what needs to be fixed and plan a strategy for disinfection. Using such tools requires advanced knowledge about the Windows Operating System and can cause system damage if used incorrectly. If you do not have advanced knowledge about computers or training in the use of these tools, you should NOT attempt to use them or fix anything
without consulting a expert as to what to fix.
