OK
what program served up the warnings? Avast?
what OS? what firewall? any anti spyware etc installed what else?
are these now in quarantine? please do not delete/remove but allow your software to put in safe place
can you post a copy of your log?
if you have these two in chest upload to virus total for analysis
then
run a manual update by rt clicking the ball
then schedule a boot time full scan by rt clicking the ball
reboot and scan
post a new log
The C:\Program Files\Alwil Software\Avast4\DATA\report\aswBoot.txt providers a more user friendly summary of the boot-time scan and it should list any detections.
post it back here
here are the instructions to send result to virus total shamelessly copied from DavidR
You could also check the offending/suspect file at: VirusTotal - Multi engine on-line virus scanner and report the findings here. You can't do this with the file securely in the chest, you need to extract it to a temporary (not original) location first, see below.
Create a folder called Suspect in the C:\ drive, e.g. C:\Suspect. Now exclude that folder in the Standard Shield, Customize, Advanced, Add, type (or copy and paste) C:\Suspect\* That will stop the standard shield scanning any file you put in that folder. You should now be able to export any file in the chest to this folder and upload it to VirusTotal without avast alerting.
If it is indeed a false positive, see
http://forum.avast.com/index.php?topic=34950.msg293451#msg293451, how to report it to avast! and what to do to exclude them until the problem is corrected.
hopes this gets you started
