My online scanner keeps informing me of an attempt to access my computer via port 135. The most likely source of this is from an infected computer on Facebook. Can you tell me which virus/worm is trying to access my computer?
I haven’t a clue what the virus might be, but it is something trying to take advantage of the DCOM Exploit (something which you didn’t mention as that port is the DCOM port). If your OS is fully up to date you are unlikely to be vulnerable to the exploit even if it got on to your system.
The Network Shield has blocked the attempt, but that leads to the question, what is your firewall (as that should have detected it too/before avast) ?
