Trojans - HTML:Redirector-BW and HTML:Redirector-BV

Since yesterday, I am persistently (every minute) getting warnings about these two Trojans: “Infection detected! - avast! Mail shield has detected a threat.” According to the pop-ups, the URL is (null) and the file is “FullDetails.html”.

I am running a MacBook with Office for Mac 2011. These messages appear only when Outlook is open. I have run a full system scan and no infected files were found. All software is 100% up-to-date.

Do these warnings mean that avast is protecting me, or am I vulnerable? What else should I do? Thanks!

By the way, I have changed all account passwords. Still no joy.

All solved by itself - or rather by avast, as soon as avast virus definitions were updated earlier this morning. I guess they spotted this issue and fixed it.

It’s back! Just now, after nothing since my last post on 18 June. Should I sit back, relax and wait for the next virus definitions update? Or is there anything I can do?
