A new, free, web-based service from cyscon GmbH tests your web browser and reports any security issues it finds.
Check-and-secure starts by checking your computer for open ports, then compares your IP address against a list of addresses associated with botnet activity.
Next, you have the option of checking your browser version and looking for out of date plugins like Java, Flash, and Silverlight. This is arguably the most useful part of the service, and you can get to it directly, which is handy.
The remainder of the service consists of offers to install various local security software packages. I haven’t yet tried the Cyscon Vaccination software, so can’t comment on its efficacy.
