Hello everybody and thanks for all the comments and questions.
I started this thread about a month a go because I had the problem on one of my websites. After reading the replies I soon discovered that I had the same problem on all of the websites I look after (around 20 of them!!) What a weekend I had deleting and changing passwords. It also created problems with the feeds on the wordpress sites with one site being banned because of this problem.
I have noticed that there is a little bit of a reacurring theme in a lot of the replies, that is – that FileZilla is used by people with the problem. I to use the program for file transfers and have done for a number of years. I am going to post on FileZilla forum today to see what response I get from them.
Anyway, after a month I have just discovered that it is back on one of my sites (and I haven’t checked the others yet due to having to delete over 15,000 files added to the site!!!). My question is this – as anybody got a definitive answer in how to remove this problrm for good? And how did it start? I have AVG antivirus and adaware with automatic virus checks setup for 4 times a week. Yes, I have had viruses on my computer but I have not worked on some of the sites that got infected for months but they still got infected – How?
This is the most frustrating time for me because I have people relying on me to look after there sites.
