Hi,
to clean IM you have to go to http://webroot.com and purchase new window washer . They also have softwares to protect your privacy while surfing , and Spy sweeper is very good to find if someone placed something in your comp to monitor you . They give you 30 days free to try out spy sweeper . It is important after you buy window washer to revisit regularly http://www.webroot.com
for new plug ins .
Best thing of all is to buy from http://mcafee.com package called 'INTERNET SECURITY ' for about $80 . That is online firewall plus, online virus scan , online privacy and spam protection , and while you are connected or not , they monitor your comp, like bodyguards . In addition, i'm using also window washer from webroot.com , internet alert, ad-aware , and snooping myself in my computer files , checking like registry , cklick on 'start ' then 'run' ..type 'regedit' and 'enter' and you got preety much all stuff in your comp but just read . Also, in 'c' dir you can check many things . If you search web , you can find software firms that sell you program to discover if someone, like your wife , boss installed spy program which is invisible to you, but remember and save every word you type, email, pages and all activity . Only person who installed and know password can read stuff .
Good way for home users is to setup password on comp , so only you can use comp . It is cheaper to buy other members of family second computer , when more people using same comp , just click with roght mouse on icon of some isp show anyone your file cabinets, saved emails, address book , without logging to isp .
REMEMBER , no washer can erase all tracks, you have to go byself to 'c' directory , then click on 'windows' then 'cookies' to check if it is clean folder , after again 'windows' then 'temp' folder and delete everything you find , after same with internet temp files, total 3 .
Also, to clear best is way to click on 'start' ...''programs' then 'accesories' then choose 'system tools' and finally 'disk cleanup ' and later in same field run 'scandisk'.
Also , to trick computer , because despite you erase cookies , you cant erase couple files , what I do is to go in windows section and delete folders 'tem' and 'temporary internet ' and ' cookies' . It is ok since comp will recreate new ones when you surf , but file will start from recent day .
You can protect comp but takes time on daily bases , anyway internet is started in order that goverment can read your email or behaviour in life .
It is much faster than go to post office and snoop in mail , I believe that every internet user have 'file' in secret organization like ins, cia etc where is all stored . Later , by searching with keywords of interes , they are taken out , recheck and put back . Welcome to Earth, global village .
