Virus, malware and other malicious software removal. Keep your computer clean and protected at all times.
Is your computer manifesting one or more of the following symptoms?
- Overall performance is unusually slow, extremely unstable and computer just ceases to work
- Your screen disappears and a blue one pops up in its place with a cryptic message saying “Windows has encounter an error and must shut down…” So called Blue Screen of Death (BOD)
- Unexpected pop-ups and unusual or offensive content
- The home page of your browser has changed unexpectedly or hijacked
- Your antivirus software has been disabled and doesn’t allow updating virus definitions

Here’s some resources to help you understand the terminology of various infections.
Macro Viruses, also known as macros are viruses embedded in other software applications to infect and spread to other files viewed by that software. I.E. MS Word and MS Excel can become infected with macros and macro viruses which can spread by exploiting their commands.
Worms are programs that duplicate themselves and use communications such as email to get proliferated by accessing your email address book and send themselves to all recipients from the address book.
Boot Sector Viruses: Boot Sector Viruses are an older type of virus and not so common. They used to infect a computer’s startup program so that the virus would become active as soon as the computer operating system starts up.
File Viruses: File viruses attach themselves to other software. When the software is run, the virus first loads itself into memory so that in can further infect other files or begin damaging the computer.
Trojans: Trojan Horses are programs that claim to perform a particular function but in fact do something different. They could infect your computer with a virus or potentially erase your files. Backdoor Trojans are programs that allow other computer users to remotely control your computer via a local area network or the Internet.
Ransomware is a type of malware that prevents or limits users from accessing their own files and system. The compromised system typically display messages forcing its victims to pay the ransom through certain online payment methods – very often in Bitcoins (฿) – in order to regain access to their files or to get their data back. Some ransomware such as Cryptolocker or Cryptowall encrypts files rendering them useless unless unlock key is obtained from the assailant – for a fee. The best defense against ransomware is a comprehensive data backup strategy.
Scareware includes rogue security software and tech support scams. You might receive a pop-up message claiming that a gazilion pieces of malware were discovered and the only way to get rid of them is to pay up. If you do nothing, you’ll likely continue to be bombarded with popups, but your files are essentially unharmed. A quick scan with your anti-malware software will likely get rid of those annoyances.
Adware: Is to internet browsing as spam is to email Adware can profile your online surfing and online shopping habits and or placing annoying pop-up adverts, installing additional IE menu helper bars. Often Adware revolves around targeted advertising based upon the web sites you frequent and you may not even be aware that the pop-ups are not coming from the actual web site visited itself but from the Adware software running locally on your machine. Quite often these applications are installed by stealth or by deliberately misleading users to install software that is not required.
Spyware: Is potentially a higher threat than Adware as it often collects user personal details, such as software installed and often sensitive information such as passwords and even credit card information which are then sent to via the internet to a pre-designated central collection point. Spyware is often installed covertly or by accident via pop-up windows with active-X controls which report that they perform certain, legitimate functions while they are secretly installing malicious programs.
Malware: malicious, intrusive or otherwise annoying and software created with the intent to infiltrate or damage a computer system without computer user’s informed consent. Malware programs tend to contain viruses, worms, trojan horses, spyware, adware and other malicious and unwanted software.
Page Hijackers are applications that redirect links to specific web pages’ URLs, I.E. a request to go to a search engine URL gets redirected another designated address instead, related to the initial link but often containing advertising or adware.
Rootkits are programs that enable administrator-level (root) access to a computer and allow an attacker to mask intrusion and obtain root-level or privileged access to the computer or entire network. Read more on rootkits
