Hi kilegoty
I notice that you have more than one anti-virus programs on your machine (Command Software (authentium) & Symantec). That's not a good idea!!

This messes up the machine pretty badly. Alike firewalls, anti-virus programs have conflicts co-existing with each other & may produce undesirable results. Pleaseuninstall ALL leaving only one of them.
ALL the antivirus programs must be removed via add/remove program.
For any program that doesn't have an add/remove entry, you will have to do this:[INDENT]re-install the program -> reboot -> uninstall[/INDENT]## Do NOT proceed with the rest of the fix until you have resolved the dual antivirus programs ##
