One of the reasons why I switched to AVG 8 from AVG 7.5 was the bumph which said that 8 was faster etc. So you can understand my disappointment when I tried a scan and it took more than three hours!!! The previous version took less than half that time. (I found Link Scanner disabled, and changed that to enabled before scanning. Could this be the reason why the scan took so long?)
Like you I am finding AVG8 takes twice as long to do a scan, and, as I am not usually on my computer for hours on end, I'm having to stay switched on for scans to complete! Bit annoying! I've also noticed since installation that my computer takes slightly longer to start up and shut down, a minor irritation though!
I'm sorry I can't answer your query about Link Scanner, but if you look back on postings about AVG8 (and there are lots of them) you might find the answer.
Thank you for your reactions. I decided to disable the Link Scanner components back to its state when I first opened the program. I then scanned again and the time taken went down an hour on the first scan.
Of course there was a message saying that my machine was not wholly protected, so I am not sure that I did the right thing but I don't think a scan should take more than three hours, so I shall keep tring to found ou what seems to be wrong
