My computer apparently deleted my user account. What can I do to get it back?

Sorry, I know this is long, but I'm not sure which details are important and which are not.

Several days ago I got 4 messages from my virus protection saying threats had been detected. Two were Trojan Horses, and two simply said malware had been blocked. The messages also said no further action on my part was needed. Unfortunately these warnings repeatedly popped up whether I was online or not. I tried shutting down and restarting several times to no avail. At some point it began freezing after going to the welcome screen record time frozen on the welcome screen is 3 hours. Dug out my user manual, and figured out how to run a diagnostic which said there is nothing wrong with my computer, but it continued to freeze on "welcome" found that sometimes I could get in by hitting F12. Then one day I flinched, and for all lack of a better description double clicked on F12. Now my user account shows up, and seems to accept my password, goes to the welcome screen, then just when it looks like it's going to go into my account it says "logging off' and returns to the screen with all 3 accounts on it.

Again I apologize for the length of this question (sad story?)

    Try this:

    Firstly, boot your computer to the Safe Mode menu screen. You do this by repeatedly pressing F8 as soon as you boot up. Once there, use the arrow keys to highlight Safe Mode with Networking. Continue to boot from there, by pressing Enter. You will now see some drivers being loaded. There will be a pause at some point. This usually lasts for no more than 30 seconds.

    If that's successful, download and run TDSSKiller.exe from Kaspersky Lab. It's tiny, and takes just a minute to run. It hunts down and kills a specific family of rootkits:

    Regardless of the results, download the free version of Malwarebytes' Anti-Malware (MBAM). Install it, get updates and run a full scan (still in Safe Mode). This is a direct download link. Copy and paste it into your browser’s address bar, and press Enter.

    After that, boot normally and run another full scan with MBAM. It will detect any malware that wasn’t running in Safe Mode.

    If the problem still exists, download and run the free Kaspersky Virus Removal Tool:

    http://www.kaspersky.com/antivirus-removal-tool?fo...

    You should now delete TDSSKiller.exe and the Kaspersky Virus Removal Tool, as updated versions are often made available. Malwarebytes' Anti-Malware can be easily uninstalled, should you wish to do so, but it may prove to be beneficial in the future.

    Hope this helps.
