It seems ever since I installed AVG 8.5 three pc users licence my computer has got slower. Each morning when I bootup it takes some 5 or six minuted before I am able to use the pc, the light on the computer keeps clicking away and makes it difficult to load a program to start using it. This never happened when I used McAfee.
I have been using AVG for 8+ years now without any problems on 3 computers. If it is taking 5 to 6 minutes before you can use your computer I think you have far bigger problems than AVG. I suggest you look at what is actually starting when you boot up, maybe do a little maintenance and "clean" your system. Also ask your self "How long is it since I did a defrag ?" All these things point to slow startup. You should also be running AVG 9.0 now (latest)
is everyday on startup a automatic scan starts. Who is you ISP with? sometimes a lot of ISP's give you free internet security like O2, BT, Virgin, Sky etc McAfee seems to be the prefered nowadays and there is no subscription on them. Just ask your ISP if your unsure on what your entitled to.
If you look at tools/advanced settings/schedule etc you can control when a scan/update occurs.
If you do not check these items you will continue to think it is the software.
brindly I have been having slowing down problems recently and have found this is NOT AVG it is Automatic Updates from Microsoft. I have turned off Auto and the machine run quicker now. This is via the normal control panel and to stop alerts just change the way Windows Alert you on the same screen as Notify and Auto appears.
