    Scanning while working on PC

    Is it okay to do so? Will it slow down the scan very much?

    Thank you, Acer

    Long ago, there was a time when men cursed and beat on the ground with sticks. It was called witchcraft.
    Today it is called golf!

    Using AVG8 Free, scanning C. So far it has taken 2 hours and I certainly don't want to do anything to slow the process down....

    If you are scanning "C" (sometimes referred to in AVG as "whole computer", though it of course can be several partitions) there are some settings you can check.

    Actually there are separate settings for if only scanning specified files or folders, or using the right-click extension, as well, but let's forget about those two for now.

    For "whole computer"; to do a one time change & scan, and not save the changed settings, in UI click "Computer scanner" to the left, under Scan whole computer click "Change scan settings". If you changed anything you can then click directly on the "Start scan" button. If you would like to save the settings for future scans, click "Save the current settings". You can also set the default settings to be used in Tools | Advanced settings.

    Let's say you scan the whole PC less often than you scan individual files (such as downloads or email attachments) or folders; then it can make sense to adjust the settings for what to scan and how to scan.

    Since scanning the whole PC by its nature takes more time, but not every file is likely to be changed since the last time scanning, one can at least try to exclude scanning some files; archives is a good example. It can take a considerable time to scan inside archives, and Windows has some, if you have downloaded large setup files or created own archives they are also included. And since they are rarely changed you would be scanning the same archives time after time.

    But of course at some point in time one should scan everything, then one can use the temporarily settings mentioned above, or perhaps schedule it since it may take some time.

    By tweaking the “whole computer” scan settings I cut the scan time on one PC from around 60 minutes to around 12 minutes. However, do please note that in my mind it is difficult to compare scan times. Since the hardware is different between peoples PCs, running programs are different, the size of the scanned data is different and last but not least the mix of the data can be very different.

    And at last, as you have seen there is a “Scan process priority” setting, which you can tweak to suite your needs. If you need to be able to work during a scan lowering it perhaps makes the PC work more as normal during scan; and Fast scan is, well, fast (or at least faster). It’s mentioned a bit in the help file. At default it is set to "Automatic scan; medium resource usage, recommended value". If you do not plan to work on the PC I see no problem with increasing the speed. Have not heard anything about changes in detection rate etc.
