Wife's facebook groups & forums seem to be visited & discretely vandalized by an uninvited guest. Don't know how he's gotten access. The call is sounding to nuke the home C drive & reach for a back up. That's no problem. But I don't believe someone can access the PC. Granted though its Win7x64 with only Avira pro + wifi modem. Could someone access the PC remotely nowadays? i thought that stuff got too tuff with today's AVs' & Win 7. (Emails are never opened so that door is ruled out.) To keep the peace, If you say maybe someone can enter remotely, how can i check?
