You still have active remnants of the iSearch infection, which means that there's a good chance the infection will return in its full glory:
O4 - HKLM\..\Run: [ffis] C:\WINDOWS\isrvs\ffisearch.exe
O18 - Filter: text/html - {950238FB-C706-4791-8674-4D429F85897E} - C:\WINDOWS\isrvs\mfiltis.dll
1. You probably will need to get into Safe Mode to effect the removal of the isrvs folder, and F8 is the key that gets you to the Safe Mode boot menu. The problem is that you have to hit F8 at just the right time; if you hit the key too late, the system won't catch it, and Windows will just continue to boot normally. You need to hit the F8 before the Winodws start-up screen/logo appears, so the best thing to do is to just start tapping F8 right after you turn the computer on. If you miss the timing, just reboot and try again.
2. Also, you may need to "unregister" the mfiltis.dll file before you're able to delete it. Do the following:
- Open an MS-DOS window, type the following command at the prompt, and then hit Enter:
regsvr32 /u C:\WINDOWS\isrvs\mfiltis.dll
- Close the DOS window once the command completes.
- Run HijackThis again and have it fix:
O4 - HKLM\..\Run: [ffis] C:\WINDOWS\isrvs\ffisearch.exe
O18 - Filter: text/html - {950238FB-C706-4791-8674-4D429F85897E} - C:\WINDOWS\isrvs\mfiltis.dll
- Boot into Safe Mode and try to delete these folders entirely:
C:\WINDOWS\isrvs
C:\Program Files\CxtPls
- Empty your Recycle …
