I have just started to really use windows 7 since I installed it on my Asus Desktop A8V-MX. I have noticed on two machine but mostly this one since I have used it more, that on occasion the hard drive will run almost continuos after a while. I have narrowed the issue to an Exe AVguard.exe from avira Antivirus. I am fairly certain because this process is using CPU when the issue is going on w/ the hard drive. When I play around activating and deactivating Avira in the control panel it will stop and the avguard.exe will stop using CPU power. Is this a setting I have enabled in avira causing this... or is it an issue w/ avira and win 7?? Any ideas guys... BTW... I am NOT using Windows defender, it is disabled.
