Avast blocks thanstrackr.com because it was infected with JS:Miner-C [Trj]

I know Avast is working to protect me, however how can is stop this from happening on a random basis?

I have checked all my Chrome Settings, seems to be browser re direct.

System:

Dell Laptop,
Windows 7 64Bit
Patriot SSD
Intel Core I3 @ 2.2 Ghz
8GB RAM

Suggestions?

thanstrackr.com is down >> https://downforeveryoneorjustme.com/thanstrackr.com
could it be that it is taken down for cleaning because it is infected with cryptominer ?

Hi rchilburn,
JS:Miner-C is one of most prevalent cryptominers we see these days.
I would recommned to use another browser for a while to see if it is only browser infection (FF, IE ). If yes reinstalling your browser should help.
Thank you for report !
