Optimise you PC for $9.99 rather than $49.99

http://www.PCPitstop.com has a code http://forums.moneysavingexpert.com/showthread.html?p=27418491#post27418491 that gets you their all for one PC optimisation software for $9.99 rather than $49.99. You can pay by either Card or Paypal. It is a black friday offer and expires midnight 30/11/09 but that will be US time.
It is a great buy for so little outlay. It will help check for malware, viruses, slow boot up and general updates for your PC, drivers for instance.
It doesn't replace a resident Virus checker but helps. It allows you to perform a free scan first just use the Free Scan PCmatic icon on the screen, download the application, run it, check the warnings, tips and recommendations. Either then fix them yourself or if your lazy like me use the code buy it for about £6.25 and it will do it for you for a year.
