Posted on wrong section. Sorry.

i turned on my computer today, and avast dectected a malware called
Win:32:Rootkit-gen[Rtk] on a filename: G\AutoRun.exe
I automatically pressed delete, but action failed, even “move to chest” option failed as well.

So i went and look for this G:\AutoRun.exe file
and found that it is actually the autorun file of my 3G mobile broadband modem (Huawei)

i’ve had this modem for like a year already, and this is my first time having told that there’s a malware inside

is it false alarm or what should i do then?

thx for your help!
