I Right clicked an ".exe" which immediately followed with an explorer.exe crash.
It then restored itself. and i saw internet go on and off.

I am curious if just right clicking an exe can cause a virus.
Cant really reboot now i have so much work open.

Right-clicking shouldn't open a file or run a virus, unless something already injected itself into the context menu. Most likely there is something in the context menu that crashed (hooked from the registry), or something else is causing issues with Explorer. You may be best asking in the "Am I Infected?" forums, some scans would need to be ran to investigate.

You should save your work, it will be inevitable to reboot the computer during investigation. While you're at it, make sure you have proper backups of your important data in the event something happens.

Funny you say that :)
I am actually in the process of backing up my PC.
Was going for a format because i crash with certain games.
Tried the whole driver update this and that already.

Concerned i might be backing up a virus though. :/

1) can you submit the EXE to VirusTotal and post the link to the report here?

2) when you right-click a file in Windows Explorer, helper programs "embedded" in Windows Explorer will access the file and might read it to analyze it. These helper programs (DLLs running inside the explorer.exe process) might malfunction, and make explorer.exe crash. Do you know what helper programs you have installed? Is your right-click menu just the default menu, or do other options appear (a popular one is WinZip).
