On running AVG(free)it frequently detects a Trojan Horse Java/byteverify(classload.jar).On reading details on this it claims it`s a Microsoft VM security vulnerability MS03-011 but i have all relevant security updates/patches.
I ran Panda online scanner which detected and disinfected the virus and thought that was the end of the matter,no on running AVG a day late it detected it again
Windows 98
Browsing Mozilla/Firefox but still using IE6 for some tasks
