beware of trojan horses
Viruses are the biggest scourge of computer user and even experienced users can be caught by them. There are a lot of programs on the market and most of them are effective as long as you keep them up to date. The free edition of AVG is a bit more basic than the full featured commercial products, but does a good job of basic protection.
You don’t have to be surfing to dubious sites or file swapping to have your computer clogged with spyware. Even respectable websites can add tracking cookies and data miners. We recommend using at least two spyware removers, which you should run every few weeks to keep your system clean.
Our current favourite is Malware Bytes, but there are plenty of others that are both paid and free.
Spybot looks for software that snoops on your web surfing while advertising software is the target of Adaware. Using the two together catches most of the unwanted rubbish that can clog up your browser. We recommend running them once a month. Like virus checkers, they need to be kept up to date
