Unexplained behaviour, possibly a virus

I'm experiencing odd behavior from a new build PC (about 3 weeks old).

Seemingly at random, when I boot the machine, NOD32 anti-virus real time protection does not start; if I then restart the machine, real time protection starts ok.

I'm also finding that programs are getting corrupted for no explicable reason - when I start them they simply hang, or if they do start, won't allow saving. In the case of Photoshop, I can resolve the issue by copying a saved version of photoshop.exe back over the top of the existing file in the appropriate folder, and restarting, which would appear to suggest that it's the launch file that is being corrupted on program start.

I have worked through the malware removal guide in full and attach the first four log files.

 

Fifth log file attached.

 

Welcome to MajorGeeks, jammin606

Your logs are clean.

You should try asking Software about the issues your experiencing as they are not malware related.

Good luck!

If you are not having any other malware problems, it is time to do our final steps:

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" /uninstall
     • Notes: The space between the combofix" and the /uninstall, it must be there.
     • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
6. 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.
7. Go to add/remove programs and uninstall HijackThis if it present
8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
   related to MGtools and some other items from our cleaning procedures.
9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
   • Refer to the cleaning procedures pointed to by step 7 of 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.
10. After doing the above, you should work through the below link:
    • How to Protect yourself from malware!

 

Will do. Many thanks for checking the logs, much appreciated.

 

No problem.
