I thought I'd already posted my HJT log/questions here previously, but apparantly they either weren't received, or were removed under the assumption that I was "double posting". In the event that the latter happens to be the case, just want to clarify--they're unrelated. Could someone explain the following lines of the log (function/origin)--log posted thereafter: O23 - Service: D - Unknown owner - C:\DOCUME~1\HP_ADM~1\LOCALS~1\Temp\D.exe (file missing) O23 - Service: FRNNCGO - Unknown owner - C:\DOCUME~1\HP_ADM~1\LOCALS~1\Temp\FRNNCGO.exe (file missing) O23 - Service: IX - Unknown owner - C:\DOCUME~1\HP_ADM~1\LOCALS~1\Temp\IX.exe (file missing) Also, there are file in temp folders which won't delete, and while they seem to either appear/disappear or change names, they always begin with "~D..." (currently,~DFABF2,~DFC764,~DFE682). There's also one called "Perflibdata_..." it seems to appear with different numbers at the end, i.e. "Perflibdata_30", but it won't delete. What are these? Following is the HJT log--please offer any suggestions re non-vital fixes, as well. Thanks! ...will running AVG anti-virus and Zonelabs sec suite (anti-virus) simultaneously cause any problems re virus detection?
