That text popping up behin dthe logo looks a bit daggy
"viral detection" should be "virus removal" - two reasons - 1: people are not looking to pay someone to detect viruses. They are paying to have them removed. 2: accordingly, no one is searching for 'viral detection' - thats a dead keyword by comparison.
On that subject your site has virtually no SEO potential. You need to look at the entire layout and content in this regard. The latest Google algorythm change will not even look at your site without content. In other words its a penalty factor that will negatively affect, if not kill altogether, your competitive organic results. By content - you should be looking at at least 300 words per page, keyword optimised, with appropriate, page-specific images and tags.
The site looks like you got a nice graphic done and then just dropped the ball on the whole task, and walked away.
It lacks useful information about your services, and there's very little reward for people visiting it. No 'content'
There are no calls to action
I like the colour scheme and the graphic/logo is really very pleasant to look at. Good job for those aspects.
What you do need to look at is navigability, content, and your marketing approach, particularly in regard to selling services.
Its not the same thing to say "we do this" in the hope people will be inspired to contact you and spend money, as to convince them why they should contact you and spend money, as opposed to doing that with one of the 10 other browser tabs they have open from their initial search for 'computer repairs'
Theres a lot more work to do to turn it into an effective marketing tool that will work optimally to bring you income.
