Ensuring new PCs and systems have been updated with the relevant security patches and antivirus updates is creating a headache for resellers.
While companies such as HP make sure the latest version of an operating system, with patches, is pre-installed at factory level, once it reaches the channel the onus is on the reseller to update new vulnerabilities, unless their customer wants to apply security themselves.
HP security manager Shaun Hobbs said: "We give companies and resellers advice on the latest patches and virus files and they decide the best route for them."
But according to Mike Lawrence, managing director of reseller Bentpenny, many companies, especially SMEs, lack the expertise or knowledge to ensure vulnerabilities are fixed in time.
The problem is compounded by the increasing number of viruses - such as the MSBlast worm - and vulnerabilities that are being uncovered in operating systems such as Windows, he added.
"Ensuring patches and antivirus software is up to date is a major headache for resellers. It is also a major cost as we have to take the PC, plug it into the internet and download patches and update any antivirus software," said Lawrence.
When a system leaves the reseller, it can be wide open to attack unless the purchaser has the expertise to keep on top of all future updates, explained Lawrence. And if the purchaser lacks this expertise, the reseller often ends up shouldering the blame.
But some resellers believe this can help the relationship between reseller and customer.
"It lets us build closer relationships with our customers if we stay in touch and offer value-added services," said Jonathan Taylor, marketing manager of reseller TrustMarque.
