My computer is using avast antivirus. My homepage is 6781.com/?k. And it contains a virus.

Question

I tried to change my homepage but the problem presists. I deleted the temp files but the problem presists. What shall I do?

Answer 1

It certainly sounds like you have been infected with some kind of malware. Unfortunately, if you find one infection, it is highly likely you have another one. A virus, trojan or worm are all different types of infections/malware and there are some great FREE programs that can help you.

First, clean up (delete) your cookies, temp files and temporary internet files. I prefer to use Ccleaner to do this, rather than the built-in DISK CLEANUP, as I feel it does a much more thorough job - for example, it will clean out the index files on your next reboot.

If you want to use Disk Cleanup, you can find it if you:

- Double-Click on My Computer to open it up

- RIGHT-click on your C: drive

- Choose PROPERTIES and then click on the DISK CLEANUP button

- When done, reboot your computer.

Delete these files daily or run Ccleaner every day right before you shut your computer down.

2 - You should also have a good anti-virus program to help protect your computer. AVG FREE, Avast or Avira are excellent anti-virus programs. You can't go wrong in choosing any one of these 3.

3 -Since NONE of the anti- spyware or anti- adware programs are 100% accurate in finding and removing spyware, you need at least two programs which you will run one after the other, not at the same time.

There are three excellent free ones:

- Spybot, Search and Destroy

- Ad-Aware

- Spyware Blaster

You will need to download, install, update (and IMMUNIZE in Spybot) and run them, one at a time. Be careful with the NAME of these programs - there are "look-alikes" with very similar names, that are in fact spyware themselves! Reboot after you install each one!

After this current infection is cleared up, be sure to run both of the above programs at least once a week if you are on the internet frequently and/or like to download music or files.

NOTE: Some infections prevent your from downloading the above programs. You may have to use a clean computer to download the programs and copy them to a thumb drive or CD. Then transfer the install files to the infected computer and run.

--Occasionally you will not be able to run these programs without being in SAFE MODE.  To get there, reboot your computer and tap the F8 key, repeatedly until a menu comes up.  You want to choose SAFE MODE WITH NETWORKING.

4 -You should also have a good firewall to help protect your computer. Zone Alarm makes a totally free version (watch you don't download the 30-day free trial of the paid version). You can download this from the manufacturer at zonelabs dot com

HTH : )

Good luck!

PS - Most of the above programs can be found at www.download.com

i. Malware can sometimes be restored from previous restore points, this will help the removal process run more smoothly

back out of Temp folder and continue to Windows folder

open Windows folder,open the 2nd Temp folder and repeat steps as in 1st Temp folder

STEP 5. REMOVE PROGRAMS ADD/REMOVE PROGRAMS

GO TO ADD/REMOVE PROGRAMS TO CLEAR KNOWN MALWARE

1. Before scanning the computer you can remove certain malware programs from the Add/Remove Programs list in the Control Panel in Windows XP

2. Open the Start Menu and select Control Panel

STEP 9. ok ! now it's time to reboot and allow normal boot up.

once connected,download and install the freeware listed. update each and THEN run.

Trojans, Worms, Key Loggers, Viruses, and Spyware are all very difficult to remove with just a single program. That is why it is recommend to run several programs to aid in the removal process. I recommend running each of the following programs listed below in order. Not all the programs are freeware and require purchase, you don’t have to run that program but I recommend looking into it if the results come back with your computer still being infected. Still, after all the freeware programs have run through your computer should be clean of any infection.

NOTE: It is recommend to run these programs in Safe Mode for the best results!

1. Freeware – Spybot: This one gets a lot of advertising bots and other malicious programs.

2.Spyware Blaster: This is a powerful utility that helps to block potential spyware problems from browsers and websites.
