"some files could not be scanned" deleted browsing history and did disk cleanup

When I did full scan with avast!, I got a message saying “some files could not be scanned” and there were 88 files, one of them is this:

File name: C:\Users\admin\Downloads\install_flashplayer11x32ax_chra_awa_aih.exel>gccheck.exe
Status: Error: Archive is password protected. (42056)

So I deleted my Browsing History and used a Disk Cleanup, to delete Downloaded Program Files, Temporary Internet Files, System error memory dump files and Temporary Files. After that, I restarted my computer and did the full scan again and this time I got message saying “NO THREAT FOUND”.

Should I delete flashplayer11x32ax_chra_awa_aih.exe? I think this flashplayer file has all those 88 files things in it because when I go to Downloads I only see this flashplayer file and not the other 88 files.

Thanks!

files that can not be scanned for reason given by avast does not mean they are infected
it is just a scan error report and the reason why, no more no less

files that can not be scanned is this forums most frequently asked question so plenty info if you forum search

OK, I will do. Thanks!
