Opinion : Well,it’s troublesome doing all these steps to maintain a clean computer,the worst is,when the user doesn’t know that his/her computer is infected. Cause not all harmful stuffs has Obvious Symptoms.

Anti Virus Softwares

Recommend Avira,Avast,Norton but not Mcafee,AVG etc.

*Avira highest detection rates,excellent scannings,but the free edition only contain anti virus protection.(Top anti virus detection rates)

*Avast,second highest detection rates,excellent Boot-time scan and tons of protection layers of shields (Much more overall protection,decent detection rates too)

*Norton 2009,i think it’s an complete overhaul version,the memory usage is superb low,extremely rare,since norton is known as system hog, Previous versions used too much unnecessary memory,slows computer down tremendously. The detection rates is good,not sure how much though. The protection is advanced type as stated. Can try by downloading the trail version(Lower detection rates but memory usage is quite low)

Anti Spywares freewares

*Spybot search & destory,protects system settings and so on(Must have)

*Spyware Blaster,an anti spyware layer of protection(Must have)

*Advanced systemcare 3,nice freeware of registry cleaner + spyware defense provided by iobit. (Though the free edition lacks deep scan etc,but still useful)

*Ccleaner
————————————–…
Excellent Anti Spyware Scanners *Not protection,unless you pay for it

*Ad aware 2008

*Malwarebytes

*Super anti spyware

*Of course,make sure you use the correct settings in every software you uses,common sense.

Download Websites Recommendations

FileHippo.com – Download Free Software
Free Software Downloads and Reviews – Download.com

Reformatting

Use the detailed reformat instead of quick reformat,its much more effective but much more longer duration…it’s safer though.

Then re-download all the window updates from the microsoft website,and download an anti virus and updated it before you download any other softwares

Scannings

It’s best to scan things in safe mode,and use the folder option settings in computer correctly for scanning purpose

*shows hidden files and folders
*Un-tick hide protection operating system files
*Un-tick hide extension for known file types
*Turn off System Restore,some trojans tends to hide in there etc.

Obviously its to let it scan the whole computer or drive thoroughly. Scanning in Safe mode is quite necessary too,Safe mode is F8 key.
