I have W7, fully up to date. I have used Avira as anti virus for a long time. Recently, possibly after this weeks updates, my action centre says no anti virus found but Avira says it is working ok. I uninstalled it, then reinstalled, but the problem persists. I ran a SAS scan with no problems. Any ideas?
I just reinstalled Avira and it said spywareblaster was incompatible, so I uninstalled that. Then switched off Defender. It seems OK now. I will try reinstalling spywareblaster tomorrow! Thanks for your input.
