window explorer open my document folder on starup

[ampai]

I am a new user of avast home edition after using AVG for the past 10 years. Beginning to get use to the new AV. The only problem is after the installation, every time I start up my pc widow explorer open my document folder by default. This is not a big problem but quite annoying. I could not find the item on msconfig and I try some suggestion obtained from the net, it still remains.

I don't know what causes this but appreciate if any one can help. Thanks

Do you have anything in the Autostart-folder?

(Start --> All programs --> Autostart)

none

(Start --> All programs --> Autostart)

Not everyone have this shortcut.Even me.

Into Windows Explorer > Tools > Options
There is an option to avoid restoring the old opened folders. I suppose it's not turned on.
Is there any other infection symptom? Is your computer clean?
Maybe you could check with autoruns (http://www.microsoft.com/technet/sysinternals/systeminformation/autoruns.mspx) which other startup entries could be related to this.

This opening of a folder, my documents or otherwise, can be as a result of a missing file that has a run command to open, this happened to me some years ago and that was the cause.

onlysomeone is on the right track, but as rassel said not everyone will have this shortcut. So Windows Start button, Run and type msconfig, click OK from the pop-up window click the Startup tab and look for an entry that originates from the my documents folder.

If you find any (report those found) check and see if it is from a redundant program, it could possibly be malware that has been removed but the startup entry still exists.

If nothing is found, there are other tools to try and find where it might be in the registry, Tech mentions Autoruns, if nothing found in that then try.
