PC Matic appears vulnerable to cloud issues as we are experiencing today. This is really not acceptable. There should be the ability to run a scan with resident applications. While it's true the scan may not be completely up to date, but at least if a virus or other malware is suspected, there is a chance it could be quarantined with definitions on file. It would be better than not being able to do a scan at all. If this cannot be rectified, I'll probably have to return my 3 day old subscription. A knowledgeable code writer could quickly come up with a way to keep malware definitions resident on a particular machine that could be accessed by the scan function.
