Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation.
A virus might corrupt or delete data on your computer, use your email program to spread itself to other computers, or even erase everything on your hard disk.
Computer viruses are often spread by attachments in email messages or instant messaging messages. That is why it is essential that you never open email attachments unless you know who it’s from and you are expecting it.
Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files.
Computer viruses also spread through downloads on the Internet. They can be hidden in illicit software or other files or programs you might download.
To help avoid computer viruses, it’s essential that you keep your computer current with the latest updates and antivirus tools, stay informed about recent threats (subscribe to our updates), and that you follow a few basic rules when you surf the internet, download files, and open attachments.
Once a virus is on your computer, its type or the method it used to get there is not as important as removing it and preventing further infection. That’s what we at DESC Computers can do for you.
Spyware is not a computer virus. Spyware can get embedded into your computer by various ways (see below). Spyware ranges from the relatively harmless type, that show adverts (adware), to the very bad type that can log every key press you type, to scanning all your files and sending confidential information over the internet. Most virus checkers DO NOT detect spyware, let along try to remove it.
How did I get this spyware on my computer ?
The Drive by…
An innocent looking popup appears on the screen saying “your PC could be infected – Click here for virus removal”. Unbeknown to you, this redirects you to a website, that then infects your computer with spyware
The Enticing Sweetener…
You visit a website and see “download our toolbar to get the weather/time in 38 countries”. A toolbar installs itself in internet explorer.
The Cool Tool
Your teenager son/daughter often chat online using Facebook. Their friends suggest downloading the latest ‘smiley cursors’.
The Funny / Joke email
A friend often sends you funny emails, sometimes with attachments. A lot of these funny emails are not very funny when they infect your computer with spyware or even a virus.
The Must See Video
You visit a site to see a video, the site informs you to click here to update your video player / codec / plugin. Facebook is a great target for these videos.
First signs of spyware
Sure you can leave it alone, but I guarantee that it will just get worse, until your PC is unusable. The more harmless spyware just pops up adverts. The worse cases of spyware actually record every key press you make and send those details back to seedier sides of the internet. If you suspect you have spyware, then I’d avoid logging into anything that you’d like to keep private (online banking, using a credit card, email)
Can I not just remove the spyware myself ?
It used to be relatively easy to remove spyware. These days it’s getting harder and harder. The spyware / adware / malware is getting more and more sophisticated with how it buries itself deep within your computers files. You can try to remove spyware yourself, but you’re better off calling us in. The sooner you call DESC Computers the quicker we can remove spyware
