Hi, I recently reinstalled my parents machine and now it keeps getting reinfected with these: -Avenue A, Inc. -CasaleMedia -DoubleClick -ErrorSafe -MediaPlex -Statcounter -Zedo Spybot cleans them off but they always come straight back. Errorsafe occasionally hijacks firefox and pops up some ridiculous crap. Is there any way of immunising a system against these things so they will never come back? Here is my Hijackthis log : Logfile of Trend Micro HijackThis v2.0.0 (BETA) Scan saved at 7:11:50 AM, on 26/04/2007 Platform: Windows XP SP2 (WinNT 5.01.2600) Boot mode: Normal Running processes: C:\WINDOWS\System32\smss.exe C:\WINDOWS\system32\winlogon.exe C:\WINDOWS\system32\services.exe C:\WINDOWS\system32\lsass.exe C:\WINDOWS\system32\svchost.exe C:\WINDOWS\System32\svchost.exe C:\WINDOWS\system32\LEXBCES.EXE C:\WINDOWS\system32\spoolsv.exe C:\WINDOWS\system32\LEXPPS.EXE C:\PROGRA~1\Grisoft\AVG7\avgamsvr.exe C:\PROGRA~1\Grisoft\AVG7\avgupsvc.exe C:\PROGRA~1\Grisoft\AVG7\avgemc.exe C:\WINDOWS\System32\svchost.exe C:\WINDOWS\Explorer.EXE C:\WINDOWS\System32\hkcmd.exe C:\Program Files\Dell AIO Printer A940\dlbabmgr.exe C:\Program Files\Dell AIO Printer A940\dlbabmon.exe C:\WINDOWS\System32\spool\drivers\w32x86\3\hpztsb06.exe C:\Program Files\Microsoft Office\Office12\GrooveMonitor.exe C:\PROGRA~1\Grisoft\AVG7\avgcc.exe C:\Program Files\Adobe\Photoshop Album Starter Edition\3.0\Apps\apdproxy.exe C:\Program Files\Java\jre1.6.0_01\bin\jusched.exe C:\Program Files\iTunes\iTunesHelper.exe C:\Program Files\MSN Messenger\MsnMsgr.Exe C:\Program Files\Skype\Phone\Skype.exe C:\Program Files\iPod\bin\iPodService.exe C:\Program Files\MSN Messenger\usnsvc.exe C:\Program Files\Skype\Plugin Manager\skypePM.exe C:\Program Files\Spybot -

My first and only suggestion: GET A FIREWALL! Windows XP is particulary prone to crappy junk, and a firewall will do wonders to protect yourself. Windows firewall sucks (no offense, Bill Gates), so even a free one, such as Comodo, is better.
