This DCOM Exploit it's ordinary with Avast!.
You're not infected... but be careful.

It's your OS fully updated?
Which Firewall do you have installed?

I also recommend to hide your email to prevent spam.
Profile > Account related settings > Put a tick on "hide your email from public".

DCOM Attacks are speculative, not targeted and tries to exploit a vulnerability in out of date OS, if your OS is up to date then you aren't vulnerable to the exploit. That doesn't stop them (usually someone from the same ISP with an infected computer) trying to see if it can infect others.
 
Your firewall should be the first line of defence in this, but avast also monitors common attack ports using the Network Shield, ideally the firewall should block it and avast wouldn't know about it, but for whatever reason avast is first in line over your firewall.

What is your firewall ?
