Hi,
are you sure, that's a "Y" and not a "V"
in the filename ? Please check the spelling or better exactly copy the name from avast'S report/logfile in here
what WIN do you have ?
test the file with OnlineScanners e.g. from Trend & KAV (see below) to get a more specific name
(you need to temporarily disable AV-Resident Shields/Monitors to be able to scan the file online)
-remove the Virus/Malware and it's system modifications according to VirusInfos from Avast, VGREP, TrendMicro, Kaspersky; you might also try searching for the virus name or filename with google
general removal procedure:
- kill respective Backdoor/Trojan process with task manager
- search for the file/process names in the registry; remove the malware's startup entries in the registry
- disinfect or (if disinfection is not possible) delete the file; this may be possible only after a reboot
-Secure your system (change passwords, secure shares, install patches/updates for WIN, IE etc..)
-scan your whole system with updated avast and maybe a 2nd scanner ,e.g. TrendMicro to check whether your PC is clean
