Oh, my friend you have a "trojan horse" virus that has invaded your system, most likely from some e-mail or a program you downloaded. Do you have a anti-virus program installed on your computer? If not you are open for all kinds of problems. Investigate the internet for anit-virus and anti-spyware programs to assist in removing problem programs. If everything else fails save what you can of your most important files and completely wipe out your hard drive and reload your operating system software. IF you are affraid to do this take your computer to a computer repair shop and have them chean up your hard drive. The money you spend will save you a lot of grief in the future.
One piece of software I like is AVG anti-virus software. It can be downloaded from the net and it has a FREE download and there is a pay download. Try the free one first and if you like it buy the pay version. It is well worth the money. There is a truck load of programs on the net that will save you from furure agony. Search out the ones that you like and buy them.
In the future, be weary of e-mails that are sent by people you don't know. Or suspicious programs that you can download from the net. Some are bogus and contain potential danger. Also be weary of e-mail or a pop-up banner that states your computer is infected with a "bug" and to download their program to get rid of the "bug"; that too will contain a problem.
What Billy told you is good advice. I would add that AVG has its pitfalls - poor customer service. I had some sort of bug get in one of my PCs a few years ago even though I had paid for a two-year subscription to AVG's service and had it set to update automatically. I contacted them via email (they publish no telephone contact numbers) and was told to reply to their email with certain files from my PC attached. Long story short, the bug was preventing one of the files they needed from being copied and when I told them that, they stopped responding.
When I eventually solved the problem myself, I requested a refund from AVG for the 19 months left on my subscription but never received a response. I did some research online and found that Avast anti-virus is rated higher than AVG and also has a free edition. I have had it on three PCs at home and two at work for almost three years and no problems so far. It seems more transparent than AVG, Norton or the other programs I've tried, updates automatically several times per day and doesn't slow my PCs at all, at least that I can notice.
I use a full barrage of different free programs to kill trojans. All the programs are available as free downloads from "download.com" a really safe and good service from CNET.
I use AVG, it is OK, maybe not the best, but I keep returning to it.
Every couple months I run:
-Spybot Search and Destroy
and then run:
-Eusing Free Registry Cleaner and
to clean out all the gunk and speed things up.
If this barrage doesn't do it you can use Hijack This and RKill, but they are tricky to use.
If you can backup your data and re-install windows. If you do re-install try and do it from an OEM disk not from a hidden restore partition from the hard drive. Check your backed up data before putting it back on the hard drive. Unless you know what to do, cleaning will most likely result with time spent on your part and the malware just coming back. I do re-installs all the time for $80.00 plus data backup if required. Money well spent if you can find someone around that will do it. Send it to me, I only take two days plus your ship time.
Click the above URL and do the HOUSECALL thing. It's pretty easy to do.
It will find and kill ALL the viruses, Trogans, worms, etc. and it's free by Trend Micro.
Even the locate ISP uses this when they install a new Internet setup.
Housecall will NOT prevent future problems, that's where you need a good Internet Security and A/V program like Norton IS 2010 (highest rated by Consumer Report), or PC-Cillin, or Kaspersky, or even AVG.
Don't go a refromat the hard drive first. You'll loose everything, just take your time and do the Housecall, THEN make sure you have a good A/V and I/S program.
I got this this alert a couple of weeks ago. When I clicked on the X to close it out it was gone. Then I open the connection to the internet it was back so I X it again it left when I went to the internet it was back.
If you get this warning what ever you do, do not click on "clean computer" the warning says "Microsoft Security Essentials Alert" so you have a tendency to trust it bad mistake. It took me two weeks to get rid of it. The tech that took it out told me that if I hadn't opened it it might have been gone in a couple of hours.
Once opened I couldn't get into my administrator account it changed all password in the computer and you can't get into that account. In the other accounts in the computer when ever you need to do something a password is required, doesn't work as it has changed the passwords so nothing works.
Just hope you don't get it. As far as I could tell I got it going from one site to another on a google search. I don't even remember what I was googling.
I work at a computer repair store. The best antivirus program out there is Trend Micro Titanium. It is well worth the money. As far as other things you want to do on a weekly basis is run a disk cleanup, clear your browsing history, cookies, etc, run Malware Anti-Spyware, and Auslogic Disk Defragmenter (much better than Windows defrag)
Question, you said "My computer is sending out advertizing e mails on its own."
Are you using an on line email account like Hotmail, Yahoo, etc. or do you have POP3 where you download the email from a server into a program like Outlook on your computer?
I ask because I know of at least 3 people that have had an on line account hijacked recently. Everyone in their address book started to receive short emails with links to websites that sell things like Viagra, etc.
In each case they had to dump their email provider/address and sign up for a new account elsewhere. Then send their friends an email from the new address telling them to set their old email address as spam.
Never have gotten a good answer as to what happened but it was all in the on line email, no amount of scanning etc found anything wrong on the machines themselves.
I did the Housecall ,added AVG ,no scans picking up anything. Turned the computer off this morning , When I turned it on this evening their were more E-mails returned that I did not send. It must be in the Hotmail account ? Jeff
next computer, get a apple. 3 years, no virus, no protection downloads, nothing. just runs perfect, all the time, every time. plug a printer in, it see;s it, no disks to install for anything, ever. magnet attached power input, why doesn't everybody have this.
someone will say something negative about the mac, its not true.. they just work. go see one.
their like a 682. just work, every time
Try the above website. My limited experience is that once one of these insidious Trojans invades your system it may or may not be possible to use an anti-virus program to find it, let alone get rid of it. Most anti virus programs are designed to detect them Before they hit.
I had a bad Trojan a couple years ago and found the above website. It's got a boatload of volunteers who will work with you in a step-by-step manner to clean your system. It took a few days and a few iterations running the program(s) they suggested, but it did get rid of the Trojan.
I had my computer hijacked sending ad emails from my yahoo account for a few weeks. I went to my contacts list and edited and put a letter in from of all the addresses so if sent it would not be a good address. Ray
