Depending on the software your running and the levels of security required we can offer help and advice a popular one that we use the most is AVG.
By default, a full computer scan will check for all threats (be they viruses or
spyware). The only exception is a scan for rootkits, which has to be added to
the schedule manually. Only during these full scans did AVG hog our test PC’s resources – at other times it kept below the radar.
AVG’s anti-virus tool is available free and has a 100 per cent detection rate
certified by the independent bodies ICSA Labs and VB100. Like most anti-virus
packages, it detects viruses both by maintaining a list of known threats as well
as heuristic scanning that detects new viruses based on their behaviour.
The firewall passed a series of leak tests, both closing and hiding ports from
prying eyes, and a wizard helps novice users by scanning your PC for known
applications requiring internet access. Once completed, you can review the
applications AVG has detected.
The Linkscanner tool integrates with Internet Explorer and Firefox, and consists
of two further components: Active Surf-Shield and Surf-Shield. The former scans
pages in real time, warning you if there’s potentially dangerous link, while the
latter works in conjunction with popular search engines, placing a green tick
next to results that are rated as safe.
