My Windows XP computer contracted a virus when downloading a file a few
months back. Back then I tried to figure out what the problem was but the
computer would always freeze before anything was accomplished; all I was
aware of was that there was a mentioning about a blue screen error. The
problem worsened to the fact that my computer wouldn't operate in safe mode.
6 months later (I decided not to touch my computer until I found a way to fix
it) I was able to turn on my computer and access my account; however, I
discovered that I was not able to access the Internet. I tried unplugging the
cables of the modem and router and then replugging them with no success after
several attempts and then I attempted to run a diagnostic connectivity test
where it explained that "Windows cannot connect to the Internet using HTTP,
HTTPS or FTP. This is probably caused by firewall settings on this computer.
Check the firewall settings for the HTTP port (80), HTTPS port (443) and FTP
port (21)." I then checked my firewall setting and saw that the HTTP, HTTPS
and FTP ports were not listed as a exception and I added them and also
checked them off as exceptions. However, I was still unable to connect to the
Internet. I also was unable to turn the automatic updates on. What do I do to
solve this problem?
*p.s i have access to another computer if that helps at all
Preferred practice is to 'flatten' and rebuild a computer that has been
exposed to malware.

It is defenitely advantageous to create an 'image' of the operating system
and create a data/file backup of the affected PC.
The image can then restored to the impacted PC and the user's data/file is
subsequently restored to the operating system.
An experienced and properly prepared user can do that in substantial less
time than scanning with complex and sophisticated AV applications.
Alas, since many users are less prepared and/or lacking the experience;
Scanning with an AV apps. is the only option, unless the user consults a
computer technician.

succeeding steps 1-4:
1.Clear the (IE) temporary Internet files and the history cache.

"inetcpl.cpl" (w/out quotation marks) into the box, then click the 'OK'
button.
In Internet Properties panel 'General' tab, under 'Browsing history', click
'Delete...'button, in 'Delete Browsing History' panel, click the 'Delete
all...' button then place a checkmark into the box beside 'Also delete
files and settings stored by add-ons', Click 'Yes' and exit the Internet
Properties panel by clicking the 'OK' button.
2.Clean HDD
Click 'Start' and then click 'Run...' then type (or copy/paste) "cleanmgr"
(w/out quotation marks into the box, then click the 'OK' button. Select
