Hey guys. When I booted up windows 7 after a session of Linux, my Avast webshield was disabled. I turned it on and I am unable to reproduce what seemed to have turned it off (Last thing I did in Linux was saved images to my windows

Is it weird to have turned itself off? I had just formatted this computer, so I am not sure whether or not it is a virus. I did complete scans with SAS, MBAM, and Avast's boot scan earlier today before this happened. Only difference I made to my ntfs partitions after that was porting over some images from my external HDD while in Linux mode and editing a txt...

Logically, it is unlikely I have a virus. Here's what I have installed on my ntfs partitions:
Avast
Firefox
Flashplaer
SAS
Spybot S&D
MBAM
VLC Player
Winrar
Skype
Photoshop CS2 (legit copy, NOT a crack! The official files from Adobe's site and everything!)
Guild Wars (The game)
Renpy (visual novel maker)

The only other thing I have on my ntfs partitions for Windows 7 are images and mp3s I've ported from my external HDD while in Linuxmode.

As you can see, I haven't gone on any suspicious websites, and my web activity has been severely limited so far. So what the heck just happened here? Does Avast simply hate dual boot computers? So far, Windows 7 is experiencing no other symptoms besides Avast's webshield being disabled.

It's worth noting before I formatted, I had a similar setup on my PC, and this same thing happened where Avast's web shield disabled itself and it also had a false alarm that a steam DLL file was win32:malware-gen, though after updating Avast and uploading the DLL to virustotal, I could confirm it was a false alarm.But the fact Avast's web shield was turned off until I turned it back on was what convinced me to format to a factory setting. But now.. The webshield turned it off again, despite formatting.

Common between before and now is the fact the webshield is disabled at windows 7's boot right after switching from Linux to Windows 7. And it does not turn itself back off even after resetting (As I've said, I've been unable to 'reproduce' it, except in this instance after I've formatted)

I'm seriously scratching my head here. I don't think I'm infected, but I really don't know. I'm pretty sure I'm not, but I wonder if there's anything further I can do to make sure? I scanned the only directories I ported over before this occurred, and nothing (As they're only .jpg image files...)

What makes me further scratch my head is the fact that my old VISTA computer has most of the same files and MORE, and yet, Avast on that computer NEVER had this issue! (However, it does lack a Linux dual-boot even though I port files from my USBs while running a Linux Live CD.)

So really... Am I possibly infected? Or does Avast simply hate computers with a dual-boot setup and GRUB? Any ideas at least how I may reproduce this anomaly?

I want to know WHAT exactly went on here with Avast's webshield, because even though I have doubts of malware, this still has me paranoid as heck!
