Well it looks like I opened up a can of worms here suggesting Avast. Very interesting to see it is not OQO friendly. I was always farily happy with AVG version 7.5 on other machines but it was the new version 8 with all the rubbish on that put me off. 7.5 always performed well and did not slow down machines to any signifcant dgreee.
Anyway I was rebuilding a laptop for a DJ the other day and I had istalled AVG 7.5 on it a year ago. I had disabled the AVG as the machine was never connected to the internet and files were always transfered by USB disk from a trusted, scanned, source. Anyway I connected the laptop to the internet and got it to update the virus definitions and wow AVG updated them without updating the software.
So if any if you were happy with the old AVG but suffering under the new bloatware then.
1) Delete AVG 8
2) Dig out an old coverdisk from a PC mag and install the 7.5 version or click the link at the bottom of the page
3) Run the update and only update virus definitions.
Hope this goes so way to redeem my previous bad advice.
