Hi,I am using a Dell Inspiron laptop with Windows 7 operating system installed in it. I was unknown about my system being infected by some bad .exe file. By mistake I opened that suspicious file due to which my system became very slow and it took long time to open a program. When I performed antivirus scan it detected 30 Trojan virus and worms. So I tried to eliminate the virus as prompted by the antivirus. I restarted the system but my laptop is still slow and takes time to load the desktop icons, Internet explorer hangs after opening the homepage. I can’t even uninstall certain programs. Is it possible that virus has affected the BIOS, is there anything I can change to eliminate it. Can anybody tell me what is the problem with my laptop
