Why does this malware keep coming back?

//

When I click on a search program or email site, I see “infospace” first before the site. It slowed my computer down somewhat. I’ve had it removed but it always comes back. How can I get rid of it forever?

Infospace is actually a search engine that’s got a pretty good reputation. I suspect what you’re seeing here is some kind of intrusive adware that’s associated with that same name.

There are several possible things that could be going on here. I want to walk you through some of the possibilities and what you should be looking at.

How can I tell what is being downloaded to my computer?

//

I have a Windows 7 computer and use DUMeter to monitor traffic coming in and out of my computer. Every once and awhile, such as while I’m typing this, I can see a large download coming to my computer. I’ve checked my information area, lower right in the taskbar, and I don’t see a Microsoft icon, which usually appears when they’re downloading fixes. Plus, today’s Monday and it’s usually Wednesdays when I actually get them. I also have Norton 360 which never really tells me when its downloading definitions or other program updates.

Sometimes a big download is from someone who has sent me a large video file without asking or by mistake. I get concerned when I see such activity and I want to protect my computer. I’ve asked a number of people and searched your site for how to identify what website is downloading to my computer and I found no answers. I may just be asking the question incorrectly but I suspect you probably understand what I’m looking for.

What web site is downloading to my computer?

Yes, I understand what you’re looking for. Unfortunately, we can’t necessarily tell exactly what is being downloaded; but we can take a pretty good stab at what program on your computer is trying to do that download.

Does visiting a search-engine cached page prevent the original site from noting my visit?

//

There are times when one might choose to search a company’s web page as cached by Google or Bing in the hope of not broadcasting one’s IP address to the company by searching its active web page. Does visiting the cached version of a page provide anonymity at least from the company being searched? If not, is there a way to modify the search to achieve this anonymity short of using a proxy address?

The answer depends a lot on the specific sites that you’re actually looking at. In many cases, yes: the original site will never know that you were looking at its content that was cached somewhere else. However, in many other cases, – perhaps even most – the answer might be very different.

Why Am I Getting the “USB Inserted” Sound When I Haven’t Inserted Anything?

//

I have a Lenovo T-430 running Windows 7, 64-bit. Every time I start this machine I get the “USB inserted” sound, not once but twice. This is when there’s nothing connected to the laptop. Do you have any idea why this is happening and how I can track down what hardware is causing this and how do I fix it? It’s really no big deal but it is kind of annoying.

The good news here is aside from the annoyance of the sound, this probably isn’t anything to worry about. I have a couple of ideas.
