I think my Windows 8 64bit laptop (y510p) with 8GB RAM is infected.
I have trouble entering the windows 8 store and half the icons on the windows 8 UI are blank and don't open.
When I manage to get into the store, the update downloads but always fails eventually.
I tried to use the Windows 8 refresh tool (reinstall without losing files) but it always fails and takes me back to the troubleshooting menu. Same thing goes for reinstalling windows so all old files are deleted, but it fails and nothing at all is changed.
I use Norton 360 but it has not found anything.
Sometimes the computer runs well despite all this the whole time it is on. But the next time I boot it up theres a chance the whole time it is slow and hangs for no reason (at least according to the task manager; no program in the background is using a lot of resources to explain this).
In safe mode the laptop always works perfectly well.
