Problem with Yahoo Site

at the risk of being done for Duplication - but we think this is urgent .

OK - this is not for me but a friend - and he's wondering if anyone else has come across this .

Facts

1) he uses Logmein to check his Mother's computer - she is in the USA and uses Yahoo for e-mail and the home page, OS is XP - using Avast and some malware stuff [ don't know what :( ] Avast is up to date , likewise XP.

2) His computer [ in the UK ] is Ubuntu - using Avast and up to date too

3) USA computer is telling them that there is a Trojan detected - no evidence found BUT Yahoo in the UK is clear of this Trojan [ he checked ]. After a bit of 'faffing about ' he managed to get to Yahoo USA and found to his horror he got the Trojan warning too .

I do have a screen shot he sent me - but I'm not sure [ Mac User ] how to get it on here - and the warning is very very clear .

Has anyone heard anything about this ? Can it be cleared from this end ?

The problem is that her e-mail is through Yahoo - so till this is sorted she is rather concerned . Her computer has been scanned today and is clean.

Sadly I'll reply to myself

This seems to be a false positive according to the Avast Forums

Well at least you can have an intelligent response from yourself.
