I’ve been using AntiVir [free] for a year or more without problems and like it very much. Yesterdays update, which seemed quite substantial requiring a re-boot, gives me problems with scans locking up and not responding on completion and I am unable to update the software. I use Acronis Trueimage so restored an Image. 24 hours later following AntiVir update the problems return. I’m using XPpro SP2, AVG 7.5, AVG AS 7.5, Adaware Plus, Spyware Blaster, Spyware Guard, Spyblocker, Kerio 4 PFW 4.22 and Firefox 18.104.22.168. I also use Ccleaner amongst other odds and ends. No changes before and after the update but the problems persist. I’ve checked the Support Forum but translating from German isn’t conclusive apart perhaps from AntiVir not liking long file path names, which mine is ?. Has anyone else experienced problems with this update. Edit: Enabling Roottkit or not has no effect on theses issues. Apologies, I didn't realise AntiVir is often referred to as Avira, otherwise I might have posted this in another thread.
