I've tried those...no luck. Ok, found a little more info while "googling" and it seems that it may have been caused by a virus that this laptop had a while ago. The system is clean now, but some of the settings may still be messed up. The files are being hidden, but I can't find out how to "unhide" files on the Desktop. I did download some PDF and PPT files using a download manager into a different directory and they stayed visible. Not sure if that makes things clearer or more confusing. Thanks for the help
I hate to say this but a computer that has been infected by a virus no matter how thoroughly it has been disinfected can never truly be trusted. The best and most
sure way to remove a virus is to format and reinstall Win 7.
As you have seen there seems to be residual effects from your recent virus infection.
Ask yourself this, how do you know if the virus is truly gone?
I know it's painful but do yourself a favor and backup your data and format and reinstall Win 7.
You can reduce the pain somewhat by planning ahead.
When I'm faced with a re-install I take screenshots of my desktop so that I can more easily recreate my layout, I also take a screenshot of my C:\Program Files folder contents so that I know the programs and apps I have installed.
I then gather together any app installers I need as well as any drivers I might need.
Actually I have these files etc. saved in a folder on an external drive from my initial
install for just such an occasion.
Once you get your new install setup the way you want it do a defrag and check for malware using your A\V program. This is to make sure you have a clean system before the final step.
That step is to create an image of your new system to be used in case you have irreparable issues in the future.
There are paid programs out there like Acronis but I find that the free open source
Clonezilla Live does a great job especially since it's 100% free.
Clonezilla is a Live CD that you boot to create a bit by bit image of your entire
image.
You can save the image to a suitably sized USB flash drive or external HDD or even another partition on you system drive if you have one.
I case of disaster run Clonezilla in restore mode and restore the saved image to return your computer to the state is was in at the time you created the image.
Clonezilla can create an image of a partition or an entire drive.
It only copies the used parts of a partition or drive and by default uses a moderate compression scheme to further reduce the final size of the image.
Example: my Win 7 install is on a 22 GB partition and uses 10 GB of that's partition space.
Using the default compression scheme the resulting image is around 5.5 GB, easily fitting
on a 16 GB thumb drive.
Creating the image takes about 20 minutes and the restore takes about 6 minutes.
D\L the Clonezilla Live.iso from here and burn to CD to create the Live CD.
Clonezilla
There is info on the website on using Clonezilla Live.
I use it often to backup my system. It has saved my butt on several occasions.
I can help with using Clonezilla if you need it, PM me.
