Microsoft has pushed its free web-based security app worldwide.
Windows Live OneCare Safety Scanner, runs from a Microsoft website and doesn't require any form of installation onto a PC.
The scanner removes viruses and other malicious software and can perform basic maintenance, such as defragmenting of the hard disk, so programs run faster.
At the same time, the software giant said international beta versions of its new consumer security product, Windows Live OneCare, will be available by the end of the year in Australia, Austria, Belgium, Canada, France, Germany, Ireland, Italy, Japan, South Korea, Mexico, the Netherlands, New Zealand, Singapore, Spain, Switzerland, and the UK.
OneCare, priced at $50 a year, can be used on up to three PCs, an aggressive licensing strategy intended to compete with major antivirus software vendors such as Symantec and McAfee. The software contains anti-virus, backup, firewall, anti-spyware and PC tuning features.
The two applications fall into Microsoft's Live services, a range of web-based and desktop applications the company is developing to keep its edge over competing ones from companies such as Google.
