Hi, I’m unable to copy files to / from my external hard drive (same for a flash drive) - I’m getting a “…need permissions to perform this action…” error message. I’m running Windows 7 SP1.
I tried disabling the firewall thru the Avast user interface, but that didn’t fix the problem - nor did disabling the port scan detection option in the Firewall advanced settings (per another post I found). I even totally disabled all Avast shields, but still no go.
Any other Avast settings I should try changing? Are there any services that Avast might have stopped / disabled that might be causing the issue? Very frustrating to say the least…
Uninstall Avast and try, if you still cant do it then Avast is not to blame. I have a feeling it has something to do with Windows and file permissions rather than Avast.
If you can see the drive in Windows Explorer, but cannot copy/paste due to permissions errors might want to try installing: http://www.mcshield.net/ May fix your issue if caused by malware.
