Don't have all of those Antivirus apps on your computer, they will clash with each other and won't protect you at all...
Keep either Advast or Antivir or AVG, All 3 are good, but choose only one..
Keep AVG antispyware
Keep Peerguardian
Keep Spybot
I'm not sure about Bitdefender I have never used it...
I have AVG antispyware, Ad-Aware, Spybot...
Peerguardian
And AVG Antivirus...
I'm not familiar with moving the incomplete folder around, but you might want to set your folders back to default, hopefully they will return to normal..
