speedup my pc

[#1]

I have done the survey of computer shopper and have downloaded [ to desk top ] the clean up tools from there.
is it safe to use it thank you

got it but not read it yet.
Although did find out why AVG 8.5 free had trouble loading, the Mag "Latest" was 8.0 and the link went to AVG.com which is USA and they didnt have a free one there.  the free one is at Grisoft, which is the original site
