Worms are the most common form of malware found in SA, said Microsoft SA chief security advisor Khomotso Kganyago.
Presenting the findings of the latest Microsoft Security Intelligence Report (SIRv12), Kganyago said Microsoft’s Malicious Software Removal Tool (MSRT) detected malware on 8.1 of every 1 000 computers scanned in SA in the fourth quarter of 2011.
Worms affected 42.8% of all computers cleaned. This figure was marginally down from 43.7% in the third quarter of last year. Second most prevalent was miscellaneous and potentially unwanted software, which was found on 30.1% of all computers cleaned, down from 31.2% in 3Q11.
The third most common category in 4Q11 was miscellaneous Trojans, which affected 20.7% of all computers cleaned, down from 20.8% from the preceding quarter.
“While viruses and worms are still a big threat in SA, the general trend is coming down, so we need to look at what we are doing right,” he said.
