Multiple Problems

Your logs are all clean! Thus your problems are most likely not related to malware and you would be best continuing to work in the Software Forum where you already have a thread. Everything you mentioned sounds more like Windows OS problems and possible registry issues.

We can do one more check ( just to be thorough ) for rootkits but I don't expect to find any problems.

Run this Trend Micro RootkitBuster and report back if anything is found.

You also should update your TrendMicro software and run a fullscan just to be on the safe size.

 

We cannot comment without seeing a log that shows what it is finding and where. This could just be a false detection of the other rootkit scanner. Or is could just be left overs in system restore or quarantine folders.

Please perform our final steps and then see if anything is detected.

1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
   • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
   • "%userprofile%\Desktop\combofix" /u
     • Notes: The space between the combofix" and the /u, it must be there.
     • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
   • Delete the C:\combofix folder from combofix (if it exists)
4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
5. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
6. Go to add/remove programs and uninstall HijackThis.
7. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
8. If you are running Vista, Windows XP or Windows ME, do the below:
   • Refer to the cleaning procedures in step 3 the READ ME for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
   • Then reboot and Enable System Restore to create a new clean Restore Point.
9. After doing the above, you should work thru the below link:
