Like dogs, computers need attention or they will begin to run more slowly, fetch the news sluggishly, and chew up all of your favourite CDs. Tame man's best mechanical friend with today's Groupon: for $30, you get a hard-drive cleanup, a computer cleaning, and a virus scan at Wintronic Computers Plus (a $133.34 value). This Groupon is valid at the locations in St. Catharines, Burlington, Guelph, and Welland.

The staff at Wintronic Computers Plus scrub excess muddle from hardware and software and sweep both PC and Apple systems of viruses. Desktop computers and laptops undergo a thorough hard-drive organization, which rids drives of extraneous digital clutter and creates space for future downloaded videos of babies rapping. Smudged surfaces and cracks emerge free of dust and miscellaneous flotsam after a safe exterior cleaning. To keep computers running smoothly and free of pernicious bugs, Wintronic's technicians make a full sweep of every file to scan for errant worms, Trojan horses, and the virus that causes relatives to forward chain letters. The store promises a quick turnaround on service and offers a warranty on all cleaning and repair work.
