Well i wish you a speedy recovery.......from whatever is laying you up !
I would advise you to install (google search required for these keywords) -
1 ADAWARE PERSONAL EDITION
2 SPYBOT SEARCH AND DESTROY
3 SPYWARE BLASTER
these are FREE programmes and can be easily updated ( i use them) and have been 'bug free' for ages!
I would also get get norton AV for 2005 edition, and use Norton FIREWALL AS WELL!!!
Also be aware that there are many phishing (pronounced fishing) scam e mails being sent on the web to many millions of addresses.... they say that " as a member of our online banking ..... blah blah blah we need to verify your account details then a click here button ' If you follow that your details will be stolen by crooks and your account raided! ONLY EVER go to your banks OWN HOME PAGE FROM THE ADDRESS BAR - never repond to these emails and just delete them from your system.... If your bank was that worried about your details they would contact you by phone or letter - not an email.
As I said at the start..... I wish you well.
and enjoy your online life and start to learn a little if you can as well, now may be a good time to start! AVOID daytime TV - it is dire!
I wish you well and hope you have A speedy recovery!
