More than six out of every 10 PC users (62.1 percent) have had a computer virus at some point, a PC Advisor survey has found.

But many commenters said that although they've experienced viruses in the past, these are becoming a less common occurrence - possibly as a result of better antivirus software.

"Have had a virus but not for many a year," commented PCA forum member Devil Fish.

"Not since the days of Windows 95," wrote sunnystaines. "Had many blocked from websites by Norton since."

"I did once have a computer virus infection, but it was so long ago I can't remember much about it," added the Forum Editor.

A little over a quarter of voters (28.1 percent) insisted that they had never had a virus.

PC security uncertainty

A further complication, suggesting that the true proportion of PC users whose machines have been infected may be even higher, is the fact that less experienced users - the most at-risk group - frequently don't know if they've got a virus or not.

"A friend of my daughter had one, and it was only after her PC started to send emails to our PC that I found out about it and informed her of the problem," recounted carver. "She got a bit angry, saying she couldn't have a virus because she never went on dodgy sites."

Just under one in 10 of voters (9.9 percent) said they weren't sure if they'd ever had a computer virus.
