So I was reconfiguring my internet settings and checked in with OpenDNS. They informed me that they had detected "malware/botware activity" on my account and directed me to their malware FAQ. Basically, the FAQ tells me to get rid of the malware, but doesn't tell me how. In fact, it states: "We would suggest using a spyware removal program to address the malicious content infecting your computer. Unfortunately, we do not have the resources to offer support for its removal, though there are plenty of tools online and Microsoft offers a Malicious Software Removal Tool which is free to download. Our friends at Kaspersky Labs also offer some helpful tools for removing malware infections." But both the Microsoft site and the Kaspersky Labs site only offer solutions for Windows. Is there any way I can get a definitive check of my system for malware? I am not sure that my computer is the culprit (my roommate has a windows laptop), but it could well be, since I have downloaded a bunch of experimental productivity apps and often find myself careening around in odd corners of the Internet. Most malware scanning programs appear to be even worse malware themselves. So what do I do? Thanks. P.S. I looked into MacScan but there are some atrocious reviews on Amazon.
