Techpoint Advice - Calls spark virus alert
Paul Barfoot from Techpoint in Kenilworth is highlighting online virus scams that inexperienced internet users can get conned into believing.
A NEW Kenilworth computer centre is warning of two cyber virus threats after being inundated with calls from Internet users. Paul Barfoot, who runs Techpoint on Warwick Road, said customers were flagging up two particular computer problems.
A NEW Kenilworth computer centre is warning of two cyber virus threats after being inundated with calls from Internet users. Paul Barfoot, who runs Techpoint on Warwick Road, said customers were flagging up two particular computer problems.
The first is with a company calling from India saying they are from the Windows Support Team based in London, informing the user their machine is infected with a virus and asking that they download some software.
But Mr Barfoot said: 'As soon as they download the software, known as TeamViewer, the Indian based call centres able to remote control the computer and show the user all sorts of errors which are normal in the Windows Logs but alarm the user. They then ask for money and a monthly subscription to fix the problems. This is a scam and the errors are normal.
'The police are receiving two or three calls a day about this.' The second issue is a virus which takes control of a person’s machine, locks them out of Internet Explorer and tells them you are infected with several viruses, again asking for money to protect the machine. Mr Barfoot explained: 'This again is a scam as only the virus is the one asking for the money for a bogus subscription. 'We have had more than 20 people in the last three weeks who have been conned by these scams.'

Public Wi-Fi – the Good, the Bad and the Ugly
Published Thursday Dec 04 2010 on www.whatsinkenilworth.comFollowing on from whatsinKenilworth's Free Wifi news, we are delighted that Paul Barfoot from Techpoint in Warwick Road has the following advice for all of us.
Public Wi-Fi – the Good, the Bad and the UglyWe see them everywhere, people with their laptops sitting in coffee shops, restaurants, hotel lobbies, airports or Internet cafes glued to their screens, checking email or surfing the web.Wi-Fi (Wireless Fidelity) has made it possible for people to roam around a room or even a house untethered from a cable while still connected to the Internet. As great as all this freedom is, there are however some downsides.
First, the basics, most laptops today come with Wi-Fi access built in. For those that don’t, a USB adaptor is available for around £25. The radio signal covers an area of about 90 meters, but does not penetrate stone or metal very well.
Secondly, when you connect to a public Wi-Fi (also known as a Hotspot), you do not connect directly to the Internet. Instead there is a wireless modem in the corner (you can often see the little antenna sticking up) that is plugged into the establishment’s DSL connection. The speed of the connection will be a function of the establishment’s subscribed bandwidth and the number of people connected to it at any given time.
So, where’s the downside? Virtually all public Wi-Fi connections are not secure. Whether data encryption is enabled or not is not determined by you, but by how the wireless modem has been configured. If there is encryption, your laptop will detect this. Encrypted connections will require a password, which is why you are unlikely to encounter them at a public hotspot. Security, then, ranges from open (none) to WEP (Wired Equivalent Privacy), a very weak encryption protocol, to WPA-2 (Wi-Fi Protected Access), which is strong and virtually unbreakable when used in conjunction with a strong password.
So where do the dangers of Wi-Fi reside? Because the signal is being transmitted through the air rather than through a wire, it is not hard for someone with the right kind of equipment to intercept and read those signals. This is called sniffing. If you’re just surfing the net, there are no real dangers, but if you should go to a site, such as your bank, that requires you to provide an ID and password, that information could be compromised. In some cases even for secure connections, i.e., those using https:, the ID and password may be sent in the clear before a secure connection can be established. If the little lock icon in your web browser is closed on the page on which you enter your ID and password, you should be safe. The only way to protect this vital information is through strong encryption. Since this, for the most part, doesn’t exist at Internet cafés and hotspots, it’s best to not log into sites that have sensitive financial or personal information. The only other option is to establish a VPN (Virtual Private Network), which creates a secure tunnel between your machine and a secure Internet connection on the other end. This is something the average user is not even going to be aware of let alone know how to implement.
Just what are your chances of having your ID and password information captured while using a Wi-Fi hotspot? Who knows? Chances are probably low, but you have to ask yourself, “Do I feel lucky?” Would you leave your house unlocked while you’re out? Then why would you leave you personal information exposed?
However, all that being said, Wi-Fi is a great way to stay connected while on the go. And with a little care it can also be a perfectly safe experience.
