Avoid virus removal costs with improved anti-virus software

Computer viruses can cause significant damage to a business, compromising valuable assets and data. Left unchecked, they can also spread to other computers on your network and effectively shut down your operations. So how can you tell you've got one and how do you go about virus removal?

Common computer viruses

According to Ashley Gilbert of Total IT Australia, 70 to 80% of computer viruses are caused by fake programs, otherwise known as 'malware'.

"They take over your computer, provide pop-ups saying that you have problems on your system and you need to purchase this or that software," says Ashley. "It's very convincing." 

Malware is often spread through file-sharing websites, but even some free online anti-virus programs can contain viruses. Users should be aware of fraudulent programs that prompt to be installed.

Computer virus symptoms

Many computer viruses try to hide in your system, but there are some obvious symptoms that indicate you might be infected:

• Performance slows down considerably.
• Pop-ups appear.
• Web browsers are redirected to different sites or search engines.
• Unfamiliar icons appear in your menus.

Computer virus removal

Minor pop-ups and viruses can usually be removed with anti-virus software. But in the case of major infections, often a system will need to be completely wiped.

"Manually removing the virus and scanning can take much longer and won't always provide a result," Ashley explains. "By wiping it, you're basically guaranteed to get rid of the problem."

Stop viruses spreading

Computers in your wider office network are also at risk of being infected with a virus. The best line of defence is using a reputable anti-virus program on every computer in your network. If one computer is infected, take it off the network immediately, to minimise the time the virus has to spread.

Choosing anti-virus software

Free online anti-virus packages usually provide the minimum features rather than comprehensive security. "A lot of the time the paid ones are better," says Ashley. "Free programs only offer limited protection and you get what you pay for, really."

But some commercial anti-virus programs do a better job at marketing than protection, so users should investigate as many options as possible, and browse online forums for recommendations. 

Be safe online

There are some simple steps to minimise your exposure to viruses and prevent your business having to go through the process of virus removal:

• Don't open email attachments unless you can be sure they're from a reputable source.
• Routinely check that your anti-virus program is updated.
• Avoid using file-sharing programs.

Prevention and cure

Minimise your chances of becoming infected with a computer virus by using anti-virus software and being alert while downloading. If you suspect there might be a virus on your computer network, contact an IT specialist as soon as possible to protect your valuable business data.
