I sort of found the problem myself, I think. i'm not no [i][b]techie[/b][/i].
You rang! ;D
Ok, before you start getting off track, let’s do things in a logical order, shall we?
Run a full Avast scan. Right click on the A ball, load the On demand scanner. Then, click on each of the “drive” icons and set the scanner for a thorough scan with archives including all external and removal disks.
If you receive an error message, give me the “exact” message including any paths and filenames.
If you have any trouble running the Avast scan, then go online and run TrendMicro.
As long as Avast was properly installed, it doesn’t matter right now whether it is Home or Pro, or the version. The basic OD scanner should still run.
There are many reasons that a pc slows down. Right now, we must eliminate causes.
