Having had Win 8 installed for a few weeks, suddenly last week Defender started warning me every 5 minutes that it had quarantined a virus called Trojan:JS/Medfos.B.
I did a search and found lots of posts about the same thing, the microsoft one being here
So microsoft know about the problem and suggest having one of their solutions, inc Defender, will resolve it.
Well that's not totally true - Defender does remove the files which are created by the virus from the AppsData/Local directories - but they are re-instated every five minutes - to be deleted by Defender again.
What MS do not say is how to get rid of the actual virus, Defender does not find it on a scan, and Defender did not stop it getting on board in the first place.
I tried various solutions from the internet for getting rid of the offending program, but none worked so I reverted to a backup I created when I first installed Win 8 , and after a week everything still seems OK.
I have no idea where the original virus came from, or where it was stored - and it does leave me wondering about the overall effectiveness of Defender as an AV solution.
If anyone has any thoughts I'd love to hear them.
