Apply problem with free Avast. Please help.

Every time I scan the computer it tells me to move certain items to chest. It tells me to click Apply, but the button doesn’t work, ever, and nothing happens, making me have to close the program without doing anything. I think this may be putting my pc at harm. I have Windows Vista, if this helps at all. And I already updated Avast, but the problem continues. Any information will help. Thank you.

what is detected, what does avast say about the files?
attach a screenshot of the scan result…

It says it cannot find path (unspecified, I think?), something to that extent, and a really long list shows up. I’m sorry, I already closed it before. If you need further info, I can rescan tomorrow and tell you exactly.

files not found, or files that can not be scanned is not detection but a scan error message

files that can not be scanned for whatever reason avast give is just that, no more no less
it does not mean the file(s) are infected, avast just gave you a scan error report

avast is a antivirus program and will only take action on infected files… so since not infected button is gray and none working
when avast find infected files they are given a malware name

files not found error is usually gone if you reboot and scan again

files that could not be scanned is the most frequent asked question in the forum, so plenty info if you forum
