Hi,
A few days ago, I read that server.exe is a Trojan virus (BiFrost). My computer has this and then when I scanned my PC, the scan detected nothing. So I wonder why server.exe is undetected in avast? And if anyone has a way to help me, please do. Thank you!
Please test the file at VT https://www.virustotal.com/ and post the result.
sorry for the pic. used paint
send the file to avast lab via your virus chest…open virus chest>>right click>>click add>>browse the file>>click open>>click ok to prmpt>>update virus definationations manually now to send it to them…after the next virus database update re-scan the file in chest via right clicking on it…and if it is yet not detected send it again
can u just post the link address to your virustotal results directly here please…
go ahead and i get a another layer of protection…try out Malwarebytes free scanner… www.malwarebytes.org
scan your computer once a week regularly u can go for malwarebytes pro which is great to run along side a antivirus…
Remember: no AV is 100%
Please attach your logs.

Thanks true_indian for the suggestion. added to virus chest and submitted to virus lab. hoping for a development in the following days
U should consider yourself to be lucky!! just by having only avast u got a trojan…it could have been something more worse 
Best is it to have layered protection…see my signature for example
could you post the link to virustotal scan…as there are som info we cant see on a pic
here you go pondus
thanks! i traced the malware…i will report it further to avast!..
i hope you do. because while my MBAM is doing a quick scan, it detected 2 objects already. by the way I have my SuperAntiSpyware log. I will post it later
