Windows 7 - QUICK HELP ASAP! (need to remove Security Tool in Win7)

ok i just got home and my moms desktop which i appeared to notice a security tool....AGAIN?!? i dealt with this in vista but this is just the start? with vista was wayyyyy worse but this is just the basic meaning i can open task manager and control panel...but i wanna get rid of it ASAP before it gets much worse like in vista (which caused me to wipe and install windows 7 on it). any suggestions this time? what can i do to permanantly remove it and have my moms desktop safe liek it was before the security tool virus?
please help me asap. thank you

Not sure what you are talking about... is she infected with malware? If you suspect that to be the case, immediately download a copy of Malwarebytes and run a scan.

When you're all clean, install Microsoft Security Essentials, and use that for a security program.

well ima try that....so if i install malwarebytes, do i gotta uninstall mse? and also i think i got rid of it. i found the location of the file (took me the longest and manual way to get there (had 6 or 7 digit number) and i delete and it was in recyclle bin (and i had to find recycle bin manually through search since desktop has no icons since the virus) and then i delete shortcut in the reycle bin and erased recycle bin) now im scanning with mse and see if that can work but ima just instal malware bytes and try that. thanks

MSE is a good scanner, but I still recommend Malwarebytes for an on-demand scanner. You do not need to uninstall MSE to run Malwarebytes.

too late...i already did LOL

but ima reinstall it. so yeah. and so far it scanned almost 60,000 objects and 1 infected. now i seen how the it can infect windows 7, ima install malwarebytes on my laptop (the one i own in my specs)

I would also recommend using these in conjunction with MSE and Malwarebytes for regular PC maintenance as well.

Spybot S&D
CCleaner
Auslogics disk defrager
Auslogics registry defrager
Adaware
Tuneup Utilities 2010 (paid subscription)

^^ thanks
well i did the scan with malwarebytes and out of 80k objects, 3 were infected and 1 of them was a registry file with the name of 6 or 7 digit numbers...around there. so now it just restarted and going to the desktop...and so far its...back to normal...thanks man. i appreciate for the help...you saved me 1 hour of reinstalling windows 7 XD
i had a trouble like this on vista but much worser...2nd time on the same desktop lol

Remember, after you remove the infection, use MSE for the main security program. Some also recommend running Malwarebytes weekly or however often sounds good to you.

isn't it better to run this in safemode with networking to get the updates and a to get a thorough scan free of infected registry or startup files? that's what i was taught. i had to do this on my father inlaws pc about 5 hours ago. man was he freaking out. funny to watch though.

Naw, I don't think it amounts to a hill of beans.

I could be wrong, but it can't hurt.
