The UK saw a significant dip in its number of Windows malware infections in the second half of 2009, according the the latest research from Microsoft.
The company today released a 248-page door-stop of a report, which slices and dices the data gathered when users run Microsoft's malware-cleaning tools.
The research found 4.1 infections per 1,000 computers scanned in the UK between July and December, down from 4.9 infections in the previous six months.
The mix of the type of threats changed a little, with a slightly bigger proportion of 'malware' relative to 'adware' being found during the scans.
Malware was at 69.9 per cent, up from 67.1 per cent, while adware was down to 19 per cent compared to 21.1 per cent.
The mix was comparable to that of the US. Generally in the report, infections by country depend largely on what language the malware is written in and, in the case of phishing, which types of passwords are sought.
So are UK users getting wiser to Windows security threats? The report also finds that seven out of the top 25 threats were rogue security programs, which pretend to be legit anti-malware tools, up from five in the previous period.
