Thanks but dont worry about trying to find it. Go ahead and reformat. Yes I meant couldn't be trusted after removal only. A reformatting reinstall of the OS will do the trick.
Dont forget to get "patched" via Windows update afterwards. And of course install a AV, there are several free good ones. And antimalware. Then you should be all set again.
Normally I post these tips at close, but we didnt really resolve anything as far as malware goes but I will post them anyway:
10 Tips for Prevention and Avoidance of Malware:
There is no reason why your computer can not stay malware free.
1) It is essential to keep your operating system (Windows) browser (IE, FireFox, Chrome, Opera) and other software up to date to "patch" vulnerabilities that could be exploited. Visit Windows
Update frequently or use the Windows auto-update
feature. Staying updated is also essential for other web based applications like Java, Adobe Flash/Reader, iTunes ,browser plugins and add-ons. More and more third party applications are being targeted. Not sure if you are using the latest version of software? Check their version status and get the updates
here.
2) Know what you are installing to your computer. Alot of software can come bundled with unwanted add-ons, like adware, toolbars and malware. More and more legitimate software is installing useless toolbars if not unchecked first. Do not install any files from ads, popups or random links. Do not fall for fake warnings about virus and trojans being found on your computer and you are then prompted to install software to remedy this. See also the
signs that you may have malware on your computer.
3) Install and keep updated: one antivirus and two or three anti-malware applications. If not updated they will soon be worthless. If either of these frequently find malware then its time to *review your computer habits*.
4) Refrain from clicking on links or attachments via E-Mail, IM, IRC, Chat Rooms, Blogs or Social Networking Sites, no matter how tempting or legitimate the message may seem. See also E-mail phishing
Tricks.
5) Do not click on ads/pop ups or offers from websites requesting that you need to install software to your computer--*for any reason*. Use the Alt+F4 keys to close the window.
6) Don't click on offers to "scan" your computer. Install ActiveX Objects with care. Do you trust the website to install components?
7) Consider the use of limited (non-privileged) accounts for everyday use, rather than administrator accounts.
Limited accounts can help prevent *malware from installing and lessen its potential impact.* This is exactly what user account control (UAC) in Windows Vista and Windows 7 attempts to address.
8) Install and understand the *limitations* of a software firewall.
9) Securing IE for safer
Browsing. How to harden
FireFox for safer surfing.
10) Warez, cracks etc are very popular for carrying malware payloads. If you look for these you will encounter malware. If you download/install files via p2p networks you will encounter malware. Can you really trust the source of the file?
