Vista - Second Life has stopped working...

Hello all, i'm new to the forum and in desperate need of help.

I've unfortuantely come across a virus, win32/Heur to be exact - with many scans and vaults later i'm now clean apparently. However - i've come across an issue with my beloved Second Life.

When i click to start it it thinks and comes up with "Second Life has stopped working. Windows will notify you of a soultion."

To which obviously it never does. I've run many scans and have many logs, from ccleaner to trojan remover and hijackthis, malwarebtyes and avg.

But with the help of all mighty windows pfff - i've got this log off the problems bit in control panel...
