The location of the virus is shown as an internet URL, this means that the Web Shield intercepted it before it was saved to your browser cache. The only option given would have been to 'abort the connection,' effectively stopping it being saved to your hard disk.
So that particular virus shouldn't be on your system, however I have no idea if there is anything else.
You can also schedule a boot-time scan from within avast, right click the avast icon, select Start avast! Antivirus, Menu, 'Schedule boot-time scan...'
Panda's on-line active scan creates a folder 'activescan' and installs virus signature files in your windows\system32 folder these aren't encrypted, these files will be detected in future avast scans. Something to remember. Perhaps best to remove Panda's active scan completely and use another on-line scanner as a back-up. On-line Virus Scanners and other useful Links
