If all is good, some tips to help you stay malware free:10 Tips for Prevention and Avoidance of Malware:
There is no reason why your computer can not stay malware free.
No software can think for you. Help yourself. In no special order: 1)
It is essential to keep your OS
,(Windows) browser (IE, FireFox) 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 etc. More and more third party applications are being targeted. Not sure if you are using the latest version of software? Check their version status 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

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)
