windows cannot access the specified device, path or file

Hello Everyone. I am a 72 year old man who has tried to get to grips with computers since age of 60.

Hopefully someone can help - I have looked for an answer online but most of either does not work or is very complicated for your average man.

Windows 98 was the best operating system, everyone knows that.

Windows 7 has been treating me fine until recently.

Over the last week, 4 or 5 different programs that I have been using , wont load. They come up with the error message in the subject of this post. And it says i may not have permission to view the files? These are programs i downloaded such as skype, vlc media player, google talk, audacity, utorrent. Things like that. Only 1 did it at first, now 5. Really annoying and I cant see a reason for it. So I usually will have to download the program again, but I cant keep doing that and it doesnt always work anyway.

One idea i had , i thought it might be a problem to do with AVG virus killer thing.

I have AVG free virus killer thing but it keeps crashing. It says many files are unhealable cos theyre unabale to locate the file. and also it indicates that there is a problem with one of the AVG files. Sometimes avg wont respond . (it says not responding)

Does anyone have an idea of what I should look into ? I never had a problem with windows 98 until they started making stuff that only runs on later versions. I used to play worms on windows 98 for 8 hours a day.

Thanks
Simon - new member of this seven forum.

i would like to add. The programs that dont work and come up with the error message, they used to have a proper icon . But now they have changed. They have changed to a white icon with a window with 6 little icons inside.

WHY IS THIS HAPPENING ALL OF A SUDDEN?

Here are the results. Should I click on remove selected? Thanks
