Acer aspire one netbook won't access internet after dwnlding prgs. (Heard AVG can cause this, and I did try the free version... or maybe it was the Avira update?) My previous restore points are also all gone! Is factory reset my only option? Please help! IMy files have been backed up on WD MyBook ext HD. Did I also back up a virus/malware? Using Vista os.

Please use full english. I haven't a clue what half of your words mean... 'prs'‽
