I'm on Planet Mac, so much of the preceding is in an alien language.
What I have noticed, though, is that stuff on this site has slowed down somewhat: moving through the pages and so on. No warning messages, just a general apathy. Could be my age...
I tried to get onto this site four times this morning and every time I got a Trojan alert from my paid version of Avast. Didn't get alerts from any of the other internet sites I visited, just come back to see if this site is available and got on no trouble. Scary though.
Have just received warning from AVG when I opened the Forum so have shut down and rebooted. I thought it was just my computer but obviously not having seen all the previous posts.
I think this threat may come from an ad on the site. I don't get any alerts with AdBlocker Plus enabled in Firefox. Also (to contradict a previous post) AVG free edition does detect and block viruses in real time. That and a scan every so often with SpyBot (also free) should give all the protection you need. Paid-for AV programmes are a waste of money, imo.
I have AVG free. It has been sending alert messages every time I try to use this forum. However loads of people still posting (28th Feb), so it must be just some of us having problems. So, reluctantly, I must say farewell, until the problem is fixed. I know many of you will be devastated to lose me.
