Good Day,
I am using avast 4.8 Home edition on my laptop. 4 days ago virus camed into my pc. I dont know exactly from where it camed, but a file named “wenbsyq.sys” is created in c:\windows\system32. The problem is, avast antivirus is detecting the virus and deleting the file but I think some thing is running in the memory, which re-creates the file after certain amount of time, When avast detects the file, its prompt for Boot time scan indicating virus is been running in the memory, I have did boot time scan twice but the file is re-created when we log in. The act of this virus is sending mails to spam websites and receiving mails…etc I disabled the internet connection and the pc seems to be fine, but as soon as I enable the internet connection, An icon appear beside avast antivirus icon appearing like ambulance icon (if mouse cursor is dragged to that icon, it shows scanning services.exe and some thing else is written.) I have searched on forums of avast but I didnt found any information regarding this virus. Please help me out from this virus. Waiting for your earliest response. I have updated version of the avast. I also posted my problem to support.avast.com but got no answer.
Have a nice day.
