After being impressed with the results of my research I decided to replace my AVG anti-virus installation with NOD32. I uninstalled AVG, then downloaded and installed the trial version of "ESET NOD32® Antivirus 3.0". The result was a quite a shock! Until I subsequently uninstalled NOD32 I was unable to display any websites in either Firefox or Internet Explorer, or received any e-mail from my POP3 providers. My research didn't turn up anything like this, so I'm chasing up an explanation here before abandoning the product altogether. Any suggestions?
