On my Windows PCs I run Mc Afee's Total Protection and there is a module that evaluates web sites for security concerns. While that software is windows based there is a web based version that is free for everyone and is quite capable of assisting us on Linux. The web site is siteadvisor.com. I typically will not access any web site until I get a site advisor report on it first. I got a site advisor report on these forums before I accessed this forum for the first time, which gave these forums two thumbs up.
