Solutions: Despite security software, viruses can get through

My desktop and laptop are very slow loading websites. Something that's called "" often appears.

I have Microsoft Security Essentials on my desktop, and McAfee on my laptop. I do frequent security scans, and they don't find anything. Is it possible that something has loaded into my computers that these two programs let by? Also, I notice that when I click on the back arrow nothing happens.

Regarding the back arrow: Many sites load up your "previous site" with the page (and most likely an ad) you're currently on, so when you click the Back arrow you stay on the same page. The way to defeat this is to click the little down arrow next to the main navigation bar and then select the desired page from the history list. For Internet Explorer 9, they made this harder to do. You have to right-click the Back arrow and then select the desired page to go back to.

Yes, it is possible that neither of your installed antiviruses are effective. This can happen if you're already infected when they were installed, or if you disregarded any warning and allowed a disguised virus to download and run on your system. I recommend running Malwarebytes antimalware program at and letting it install and run, then follow directions. This is the free version. Answer "No" if prompted for the "trial version" of their "for sale" product.

I have Vista on a computer that's about a year and a half old, with Windows Mail (previously Outlook Express). I Started using Google Chrome (love it) and for some reason if I'm on a Google website and click an email address, it doesn't link to it. I also sometimes see the email address in the lower left corner with the prefix, "mailto:" showing.

Try this: Click Start, Program Defaults, then click "Set program access and program defaults." Select Custom and click the down arrow. Set Chrome as your default browser and then Windows Mail as your default email client.

A few years ago, I bought a SimpleTech External Hard Drive and used it as a backup drive. I then bought a new PC and started using that for backup as well. Now my drive is full and when I try to delete the old PC's backup folders, Windows won't allow it. I need admin authority from the other PC, which I no longer have.

Is there any way to delete folders/files that were created on one PC that is no longer available?

You need to change ownership of the files. Try this: Right-click the folder you're trying to delete and select Properties. Click the Security tab, then the Advanced button and then the Owner tab. Under Current Owner you should see the old PC/user name. Click the Edit button and select your current PC/user under the "Change Owner to" box and click okay.
