Answer 3

You can run what is known as an online scan. Trend Micro offers a free online antiviurs scanner. Just follows the instructions from the link I give you below. Please complete the entire scan an any viruses found will be killed.

Or you can download Superantispyware. This program is known to find trojans and spyware that is mised by all other. Plus you get daily auto. updates.

There is no conflict with the online scanner or Superantispyware with any antivirus/antispyware you have running.

One of the first things to do when you suspect malware is DISABLE System Restore.
If enabled, this allows malware to hide in the computer and re-install itself.
So, to disable it, RIGHT-click on "My Computer." Select "Properties" then under the 'System Restore' tab, check 'Turn off system restore' IF not already checked.
The next most helpful things that would help you are to use ONLINE scanners from websites to remove any malware on your PC.
The current best online scanners I prefer are from Kaspersky antivirus and Bitdefender antivirus. Together, these 2 scanners will find ALL the bad stuff on your PC because they have the BEST detection rate.
First, use Kaspersky's. (FYI: ALL these scans require you to agree to a EULA and install an activex control which is needed to perform the scan, so agree to them all.)

*NOTE: Some scanners ONLY work with IE or may not fully remove malware

Then scan with:

There are MANY other good online scanners which you may choose to also use (which will take longer but ensure safety):

http://www.ca.com/us/securityadvisor/pes... (Spyware scan)

http://www.ca.com/us/securityadvisor/vir... (Virus scan)

http://www.eset.com/onlinescan/......... (Nod32)

http://support.f-secure.com/enu/home/ols... (F-secure)


After using these, it's ESSENTIAL to install at least 3 antispywares. Do NOT use more than 1 antiVIRUS as they conflict.

The best things in life are FREE, and great free software can be found @:

Superantispyware.com (Superantispyware FREE version)
lavasoft.com (Ad-aware)
emsisoft.com (A-squared FREE)
safer-networking.org (Spybot S&D)
javacoolsoftware.com (SpywareBlaster, EULAlyzer, & MRU-Blaster)
microsoft.com (Windows Defender)
grisoft.com (AVG AV)
Avast.com (Avast AV)
avira.com (Avira AV)
activevirusshield.com (AOL Virus Shield, which is basically Kaspersky for free)
siteadvisor.com (Tells you how safe websites are)
phoenixlabs.org (Peerguardian blocks malware, government, and anti-p2p org's)
zonealarm.com (Top Notch Firewall)
comodo.com (Another Top Notch firewall)
iobit.com (Advanced Windows Care)
Eusing.com (Registry cleaner)
ccleaner.com (Junk file cleaner)



Now if you can afford it, the best software to BUY are:

Spy Sweeper
Security Task Manager
Norton AV (Takes a lot of CPU but it's nice if you can afford to use those resources up)
Kaspersky AV (BEST! =D )
Bitdefender AV
Sophos AV
F-secure (Same as Kaspersky)
Linkscanner (Blocks exploits in real time)
Advanced Uninstaller

If you're PC is squeaky clean from malware, re-enable system restore because it IS good to have but we needed to shut it off to wipe out the malware.
Just RIGHT-click on "My Computer." Select "Properties" then under the 'System Restore' tab, UN-check "Turn off system restore."


*Another thing to consider is using another browser besides Internet Explorer. IE has a lot of security holes,
making it less safe than other browsers. I prefer Firefox from mozilla.org.
It's just as easy to use and has a lot of neat little add-ons you can toy around with. By itself, it is also safer from exploits than IE.*


As always, things will vary for you. I hope the best for everybody. As always, others may disagree but there's only one way to find things out---try it! As long
as you have an UPDATED Antivirus, Antispyware, & firewall, things will go smoothly. And browse wisely. Hope I was able to help and fix anything needed. If I have, please consider returning & leaving a nice comment and
