i think i may be infected by a Trojan or some sorta virus.. the computer is acting very sluggish even though i have 3meg of mem and a 2 core AMD 3.2 GHZ running in vista OS.. i have done a number of virus scans, Panda, and Avast. and in the process of running a full scan in safe mode with Malwarebytes... so far no virus detected, i do notice that in safe mode i dont get near the hit on the resources as i would in regular logon..
i have HijackThis installed if you need that information... other then that im pretty well stuck, have Google all i can on the possible explorer.exe process and it says its legit, helps with display of icons and graphics in windows vista..
by Resources i mean CPU usage.
symptoms -- sluggish computer all web browsing or any application just slows to a crawl..
when i start the computer and log on i check my resource manager and its any where from 76% to 100% CPU usage..
no virus detected with any Anti Virus i have tried including MS Anti Virus Security,, the computer is just not preforming like it did a even a few days ago.. not sure what else to add but i suspect the process Explorer.exe is infected.. not looking forward to having to do a full reinstall
help,,, what is my next course of action..
really stuck on this one..
now i have ran Malwarebytes and it found Rougeinstaller and removed it..
i am now missing all my icons when i log on all i get is the mouse pointer in Vista running in normal mode.. <this is the admin account>
not sure what is going on,, but it seems to get worse and worse..
this is now going to the second day since the problem started and i posted on this forum..
now all i have after my logon is a BLACK SCREEN and a mouse pointer.. no task bar nothing.. just mouse pointer
Update: still no solution, tried to do a sys restore from safe mode.. but the problem is still there
i am able to logon with another user account and the screen is fine and the resources used are well back to normal..
ever virius check i run seems to come up clean..
ok a little farther on progress.. was able to get back to my admin account by creating a new admin account
not sure why.. and it appears the virus is gone... but i would still like some advise on how to use malwarebytes and the other deep scan tools for malware..
im not at all sure its gone..
