Passage 25

(福建省三明一中2010届高三上学期第二次月考)

What causes your computer a slow one? The problem lies with changes that occur to the PC's software. The 2 most 　51　 　causes of slowdown (along with easy solutions) are:

Registry errors 　- 　the most common problem

　 Every 　　52　 　you load a program, game or file, your PC's software registry is updated with new instructions needed to operate that item.　　 53　 , when the item is removed, these instructions usually remain on your PC.　 Every time you run your computer it 　54　 　to carry out these instructions but, because the related program can't be found, it causes a registry error.　 Your PC is doing a lot 　55　 　work than it should be and the result is a significantly 　56　 　computer.

　 One of the best ways to manage this is with a 　　57　 　little tool.　This program scans, identifies and 　　58　 registry errors - resulting in a computer that's a lot more like it was when you 　59　 bought it.　

Spyware and viruses

　 Spyware and viruses are software programs that are loaded on your computer 　60　 　your knowledge or permission.　 They have various purposes, 　61　 　:

　 Changing the default search engine in your browser

　 Tracking your web surfing 　　62　

　 Stealing your personal 　　63　

　 Most spyware and viruses get onto our computers through files that we 　64　 　from the internet or as attachments to emails.　They tend to 　65　 　up a lot of computing power and as a 　66　 　will significantly slow down the computer.

　 The simple rule of thumb to follow is to never download any 　67　 　software programs from companies you do not know and trust, especially screensavers, emoticons and the 　68　 　.　In addition, make sure you have a good anti-virus / spyware removal software running at 　69　 　times.

　 Follow the above advice and your PC should stay fast and 　70　 　.
