Yep

Yep, sounds like a variant on the AntivirusXP scam software. Only tends to affect people foolish enough to be using Internet Explorer. Particularly those foolish enough to be running an UNPATCHED version of Internet Explorer. Using IE is playing with matches, using an unpatched IE is like using a butane torch to see if there's any gas in a gas tank.

Good news is, most variants of this scam software are not malicious except for trying to sell you worthless software, and something like malwarebytes should manage to clear it up pretty quickly.

Bad news is, where there's smoke, there's usually fire. This program made it onto your system, so who knows what else could have come through the same door. You should assume that any and all sensitive information on your system is compromised. After you get everything cleaned up, just to be on the safe side, start changing passwords on every site you've been to, like a bank or credit card site. Might not hurt to ask credit card companies to place a fraud watch on your cards. At the very least, watch them VERY carefully for the next 6 months or so for ANY charges you don't recognize. Another good precautionary measure would be to have your bank transfer your funds into a new account. Leave enough for any outstanding checks you may have written, move the rest. Better that then to find someone cleaned you out one day. The bank might be interested in using your old account as a ********, looking for anyone who tries to access it so they can send the info to the FBI.

Most of these are purely preventative. Odds are low you'll need any of them, but do you really want to take that chance?

Moving on from reactionary measures to proactive, keeping this sort of thing from happening again, pay particular attention to my list of dos and don'ts. If you follow them religiously, the odds of this sort of thing happening again are next to zero. Those odds go up significantly for every one of them you don't follow for any reason. Especially the ones about using IE and file sharing programs.

Notes
--------

(1) Sadly sometimes this is unavoidable, so only use IE when the site absolutely will not work with any other browser and you cannot get that information/service anywhere else, and only use IE for that one specific site.
(2) Outlook and Outlook Express are very insecure, and basically invite spam. The jury is still out on Vista's Windows Mail, but given Microsoft's history with email programs, extreme caution is advised. Possible replacements include Mozilla Thunderbird, Eudora, The Bat, and dozens of others.
(3) When it doubt over whether or not to allow some program, use Google to find out what it is and whether or not it needs access to the Internet. Otherwise, denying access is the safest course of action, since you can always change the rule later.
(4) On Windows your options include: Mozilla Firefox, Seamonkey, Opera, Flock, Chrome, and Safari. I would personally recommend Firefox with the NoScript extension for added security, but it the important thing is to pick one and use it instead of IE.
(5) AVG Free and Avast are available if you need a decent free virus scanner
(6) XP/Vista's firewall is probably good enough for 99% of all Windows users, but other options include ZoneAlarm, Outpost Firewall, and Comodo. If you have a router with a firewall built into it, there is no need for any of the aforementioned firewalls to be running.
(7) Microsoft's usual system is to release security updates every second Tuesday of the month.
(Cool Use of Windows Update on Windows operating systems prior to Windows Vista requires Internet Explorer, and is thus a valid exception to the "No IE" rule.
(9) Service packs should ALWAYS be installed. They frequently contain security updates that will ONLY be found in that service pack.
(10) You can go with a full fledged backup program, or simply copying important files onto a CD/DVD/Flash drive.
(11) I'd recommend a tiered backup system. For example, you might have 5 rewritable DVDs, and every day you burn your backup onto a new disc. On the 6th day, you erase the disc for Day #1 for your backup, and so on so that you have multiple backups should one disc ever go bad.
(12) Replace rewritable CDs and DVDs approximately every 3-6 months.
(13) These dramatically increase the size of email messages (2-3X minimum) and clog up email servers already straining to cope with the flood of spam pouring in daily.
(14) If you want to share photos with friends/family, upload them to some photo sharing site like Flickr or Google's Picasa Web and then send people a link to that particular photo gallery.
(15) This is considered to be the same as SHOUTING and many people find it to be hard to read along with highly annoying.
(16) Unless the goal is to make yourself look like a pre-adolescent girl, or someone overcompensating for their gross inadequacies, and you don't want people to take you seriously.
(17) Most REAL hackers are quite content to leave you alone unless you make them take notice of you. No dinky little software firewall or consumer grade router is going to keep them out of your system. So do not go to some hacker website or chat room and start shooting your mouth off unless you're prepared to accept the consequences
(1Cool Most of these programs are scams, and sell you something you don't need. Most of them report non-issues in an attempt to boost the number of "issues". Sometimes using these programs can lead to a non-functioning computer.
(19) The Windows registry is not some mystical black box of untapped performance tweaks for Windows, that will lead to untold improvements in system performance. Most of the tweaks will lead to very modest performance gains of 1-2% tops, and probably less than 10% all combined. There is also a good chance that you will render your system unbootable if you make a mistake when editing. Registry default settings are set that way for a reason. Just do yourself a favor, and forget you ever heard of the Windows registry unless you are a computer programmer/debugger and your job requires knowledge of the registry.
(20) Acer now owns Gateway and eMachines
(21) HP owns Compaq
(22) Hardware failures seem far more common with these brands than can be considered normal
(23) These companies use cheap labor in Asian countries were working conditions are often what would be considered sweat shops, and are run by brutal dictatorships, which you are supporting by buying from these companies
(24) If you just do some simple math, and realize that the cost of individual components like the CPU are around 25-33% of the total retail cost of the system, and everyone involved in the making and selling of the system is looking to make a profit, how much money can they possibly be making on each system. And if you're only making a few pennies on every system, how much quality control do you really think is going to go into the manufacturing process?
