Hi, I'm having this problem and I've searched the forum
for similar problems but haven't found anything thru that

I left my computer in somebody elses hands that I trusted
for the last week or so, I've come back to it and have these problems

Whenever I select this certain folder, right click the folder, anything like that
it freezes windows explorer and then it says it has to close because it encountered
a problem, which means I have go to run then put in explorer.exe to reactivate it

and when I try to use programs that scan my hard drive for issues like viruses and spyware etc
it freezes when it comes to this folder and just stops responding
so that makes most programs to fix virus/spyware/etc problems impossible

So does anybody know what's wrong and how I can go about fixing it?

Thanks in advance
