I downloaded VCom, Fix-It Utilities 7.1.1.30 as it was offered free. I thought I would be able to speed up my computer (which is like walking through treacle sometimes)by tweaking it. However, I now see that it has anti-virus protection included. I am perfectly happy with my AVG Free 7.5. Will these 2 cause any conflict? Also does anyone have any comments about Fix-It? I see that a web-user review says version 8 can be very slow and this free one is the previous version. I'm wondering whether the fix-It will be more trouble than it's worth. I put it on defrag overnight and it only did 1%!

Any help will be gratefully received.
