Hi there guys,
I was just seeking some advice re my situation here.
I use my computer primarily for games and word processing/excel use. Occasionally I will use it to do financial transactions.
I used to have McAfee antivirus (it came with my Dell) on my computer for the last year. I remember a long time ago it detected a trojan in a jar_cache.tmp file (long time ago) that it reported it had dealt with and deleted. The computer had since been rescanned multiple times (>40) (I think McAfee has full scans scheduled at least weekly) and nothing popped up.
Recently my McAfee subscription expired so I went and bought Norton Internet Security 2012 just yesterday. I installed, and ran full scan, and voila, it found 9 new trojans, each from jar_cache tmp files in the user/appdata/local/temp folder, which apparently had a date of creation of July 2010.
So apparently I've had them for over a year? without Mcafee detecting them? I have changed my pw's to stuff prior to even knowing about these trojans, and have changed them again.
I was contemplating whether to reformat my computer, but I've now realized this will be difficult as I can't seem to find where my product key for Office Professional 2010 went (although it is currently installed on my comp). Will my computer be secure enough to continue what I have been doing without a reformat? Or should I adopt the potentially costly reformat?
Your advice/input would be great,
Thanks
