Dear Forum Gurus,
Could somebody please advise how to ascertain whether I have a virus or installed legitimate software?
Is it usual for new USB memory sticks, once plugged in, to install software to be able to read them?
I had a lapse in judgement and after plugging a new USB memory stick into my laptop a grey box appeared. It stated something like 'This USB stick requires the installation of additional software to be used'.
To be honest I was extremely tired and stressed and clicked yes. I don't remember exactly the process but it installed (no boxes appeared or anything). Can't remember if it needed a reboot but I was able to read the stick afterwards.
My computer appears to be functioning completely normal. No slow down in speed, strange messages or crashes. I checked C:\ and there was no autorun.inf file there. I even changed the setting to 'show system files' and 'don't blend hidden files out' in Window$ Explorer.
In hindsight it was stupid of me. I am now worried that I have installed malware, spyware or something else bad.
I run Avast Pro, MBAM resident, ZA Pro, SAS on demand, Window$ XP SP3.
There were no warnings from Avast. My regular scans of Avast, MBAM and SAS have detected nothing. A HJT log posted to the
www.hijackthis.de website didn't show any malicious items.
I would be really grateful for you comments, thoughts and suggestions.
Many thanks,
Avastfan1
