|I recommend that you NEVER use Spybot !!|
There have been many times in the past where it has removed the WRONG things, and if you have disabled System Restore like is frequently recommended when you suspect you may have malware on your computer, in some cases you cannot fix the problems that caused, at least, you can't easily fix that..
By the way, Microsoft experts recommend that you DO NOT disable System Restore to delete previous restore points until AFTER you are sure you have removed malware, because any malware that's found in System Restore restore points CANNOT infect your computer unless you deliberately load a restore point that has malware in it yourself.
System Restore doesn't back up everything, but if you have disabled it, you DO NOT have the option of trying loading a previous restore point, e.g. if the anti-malware software removes something it shouldn't have.
In any case, Spybot and AVAST each have one or more resident module(s).
Many anti-malware programs have one or more resident module(s) - a part that runs in the background all the time the computer is running that looks for suspicious activity. If you have two or more anti-malware programs installed that have one or more resident module(s), those modules are likely to CLASH with each other and cause you problems !
Either - disable the resident module(s) in all but one anti-malware program that has it / them, or only have ONE such anti-malware program installed at a time !
How to disable your security applications
To load Windows other than normally....
Remove any bootable CDs or DVDs you have in drives.
Boot the computer and starting very early, press F8 repeatedly, do not hold down the key, and when the "Advanced..." Windows loading choices menu appears, choose,
in this case, Safe mode, or Safe mode with networking (mode) if you want to be able to access the internet
Some computer's bioses have their own use for pressing F8 while booting. E.g. you may see a screen where you can select which device to boot the computer from. If you see something like that, READ the screen and find out which key you need to press to exit that screen, e.g. Esc. Press that key, then immediately repeatedly press F8 until you see the 'Advanced..." Windows loading choices menu.
If you're not familiar with Safe mode (without networking), when it works properly, you see a screen filled with lines that show which programs are loading, then it stays that way for the last screen full for as long as a minute or more, then the Logon screen appears with at least the built in Administrator user and your user listed, you pick a user, then the desktop screen loads, a large window pops up and you are asked if you want to run the computer in Safe mode or choose something else. (Whatever you choose, you can run System Restore to load a previous restore point.)
Safe modes use, and Enable VGA mode uses, default VGA video drivers The images on the screen will probably be larger than they are when you load Windows normally.
NOTE that some anti-malware software CANNOT run in Safe mode.
E.g. Microsoft's Security Essentials.
If you ONLY get this problem when you try to open files that were / are on the SD card....
It's likely your problem has nothing to do with malware.
Your problem may be due to
- there being something wrong with the type of file you're trying to examine that's from the memory card being opened by Windows Explorer.
Windows Explorer opens many types of files by default, unless you have another program installed that can open a file with that file extension.
RIGHT click on any file you're having this problem with, select Properties, and tell us what the file extension for the file is - the last part of it after the dot.
- It's also quite possible that the files on the SD card you copied have been DAMAGED on the memory card because you unplugged the card while Windows was running WITHOUT clicking on the Safely Remove Hardware icon in your taskbar and choosing to STOP accessing the card .
If that case,
- trying to open the exact same files you had the problems with in My Pictures that you copied on the memory card itself will probably cause the same error message.
- other files that have the same file extension as the problem files will open fine.
