I had loads of missing file messages and bits that weren't functioning. I also has probs starting my laptop up after installing AVG7, even though I did an uninstall and full reinstall twice. I think that there may be a problem with the download from the site which is causing file corruptions for some people. I suggest you download another free anti virus program such as Kaspersky or Anti Virus Personal Edition temporarily (or check your PC Advisor discs for free Anti Virus software) and wait until Grisoft start distributing AVG7 with computer mags. I'm sure it won't be long before PC ADVISOR have it on their CD/DVD.
