Good grief.
A friend of mine got a spyware and virus infestation that was more severe than anything I’d seen before. The steps for dealing with the problem went far beyond what I’d prescribed in my Public Service Announcement. Thankfully, the counter-spyware experts at The PC Guide Forums were able to walk me through the process of marking, fixing, deleting, repairing, and immunizing. I think the machine is clean now.
Right now would probably be a good time for you to update your spyware and anti-virus definition files. SpywareBlaster is also a good one to have. It puts known spyware on the shit list and prevents them from being installed in the first place. It’s free to use, but if you donate a small fee, you can enable the auto-update feature for worry-free protection.
