Hi,
First of all you are running two antivirus programs at the same time, i.e Avast and Symantec/Norton. Alike firewalls, anti-virus programs have conflicts co-existing with each other & produces undesirable results. Please
uninstall 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:
re-install the program -> reboot -> uninstall
You can use the instructions on
this page to completely uninstall your Norton Products.
Post a fresh HJT log when you have completed the above task.
