Firewall question

[unstresst]

....Using McAfee firewall
I'M also in the process of cleaning out a virus or two.
Every site I visit prompts the same firewall notice three-four times for each site.......Should I allow this--[below]--piece of traffic through the firewall??
It's labeled as: C:\WINDOWS\System32\svchost.exe
