All was well using Windows XP(SP3)and Internet Explorer with Free AVG 7.5. (Plus ZA, Ad Aware & ASquared.)
I changed to AVG 8.5 and nearly everything slowed down or froze. (I tried uninstallation of AVG and installed Avast with similar result)
I disabled AVG but on opening Internet Explorer or trying to "send/receive" in Outlook Express, I sufferred a considerable wait before a warning came up to say AVG was switched off.
Thereafter the PC would run OK until next time it was booted up.
I uninstalled AVG (Using Revo)and running without any AV prog, but theproblem remains, in that I have to wait until Windows announces that no AntiViral programme can be found. I conclude that it is some part of Windows that is causing the delay and therefore it was not just a problem on AVG. Any ideas or suggestions, please?
