I regularly advise computer users to listen to their instinct. Nearly everyone I've helped who have infected their computer say they felt something wasn't right. If you get this feeling listen to it. Nature has provided us with a great survival instinct and we should take advantage of what nature has provided.
In the article I found this paragraph relevant to readers of this blog.
Look for spelling mistakes on a business site. Pharming is a practice where cyber criminals redirect your attempt to access a site to their version of the same site. Spelling mistakes, poor grammar/english and the use of old business emblems are the giveaway. Be observant.
The problem is even the article itself contains the word "english", which should be "English". If the article you're reading has poor grammar and is written by skilled journalists, then many business sites will have poor grammar. It is a clue, but not the only clue.
The other paragraph which concerns me is the following:
Ensure your home computer/laptop/tablet/smartphone(s) has antivirus protection.
Yes. Definitely install and keep your anti-virus software up to date. However keep in mind nearly every infected computer that I've repaired (and there been hundreds over the years), have had anti-virus software installed. Anti-virus software will not catch the latest malware (there's a potential windows of 24-48 where you software doesn't know about the new malware) and do not stop many infections. Many infections are a result of the user going to a site, clicking on a link, installing free software. Even those ads you see in Google can lead you to unwanted and undesirable software.
Ultimately you're your own best defence. If it doesn't feel right STOP. Think about what you're just about to do. It may cost your hundreds. None of us are immune to being infected. I read an American police station had to pay the ransom to decrypt their data. Do make sure you have a backup of your important information off your computer.
Also to be scammed often has nothing to do with your computer. I recently had my credit card cancelled due to fraud and it had nothing to do with my computer. Another family member had their credit card cancelled due to fraud and they don't have a computer. A client was scammed simply by providing their bank customer number. I've seen the banks and telcos get tricked and they should know better. So keep in mind if the police, banks and telcos can be tricked, then if you do get tricked, don't be too hard on yourself. The crooks are very clever and do this for a living.
