help with the always fun trojan.gen

[MIZCHIFMKR]

Thank you ahead of time for any help given.
ive seen some threads regarding this however they say its usually user specific so here is mine.
I did run an erunt backup
i am currently running windows xp64 and when i try to run dds it says that it is not supported so i cannot post it.
I just installed avast and received a virus detected notice that is basically is continually being detected, by that i mean avast is continually notifying me of this detection (pretty annoying after a while lol).
the info i am getting is the following
folder and file name:
C:\WINDOWS\WindowsUpdate\update.exe
size of file:
594432
virus description:
win32:trojan-gen

could it just be a false positive?
any help would be greatly appreciated. thank you so much!

Its malware. If you havent yet download and run malwarebytes and post its log:

lease download the free version of Malwarebytes to your desktop.

Double-click mbam-setup.exe and follow the prompts to install the program.

Be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.

If an update is found, it will download and install the latest version.

Once the program has loaded, select Perform FULL SCAN, then click Scan.

When the scan is complete, click OK, then Show Results to view the results.

Be sure that everything is checked, and click *Remove Selected.*

*A restart of your computer may be required to remove some items. If prompted please restart your computer to complete the fix.*

When completed, a log will open in Notepad. Please save it to a convenient location. The log can also be opened by going to Start > All Programs > Malwarebytes' Anti-Malware > Logs > log-date.txt

Post the log in your reply.

That log cant look any better. Not sure if DDS will run on a 64bit OS. Try this instead:

• Download random's system information tool (RSIT) by random/random from here and save it to your desktop.
  
• Double click on RSIT.exe to run RSIT.
  
• Click Continue at the disclaimer screen.
  
• Once it has finished, two logs will open. Please post the contents of both log.txt (<<will be maximized) and info.txt (<<will be minimized)in your reply.
